ABSTRACT

A evolução dos tratamentos em implantodontia possibilitou uma mudança nos tratamentos reabilitadores para pacientes edêntulos, tornando possível a colocação de próteses fixas, que proporcionam maior qualidade de vida para estes pacientes. Para que estas próteses tenham bom desempenho e longevidade satisfatórios é essencial que se mantenha um padrão adequado de higienização bucal e manutenção profissional. Assim, o objetivo deste trabalho foi realizar uma revisão de literatura a respeito dos principais recursos disponíveis para higienização e manutenção das próteses totais fixas sobre implante (protocolo de Branemark), tanto nos cuidados domiciliares dos pacientes quanto no atendimento profissional do cirurgião dentista. Foi realizada uma busca eletrônica, não sistemática, nas bases de dados Lilacs, Pubmed/Medline, Scielo e ScienceDirect, cruzando-se os seguintes descritores: "Higiene Oral"; "Implantes Dentários"; "Implantação Dentária"; "Manutenção"; "Prótese Dentária Fixada por Implante" e "Prótese Dentária". Foram consultados artigos de revisão de literatura, revisão sistemática, meta-análise, estudos clínicos randomizados, além de livros pertinentes ao assunto, publicados no período de 1995 a 2022.Verificou-se na literatura disponível que os principais instrumentos indicados para uso domiciliar são escova dental, fio dental, escova interdental, irrigador oral, dentifrício e enxaguatório. No atendimento profissional em consultório odontológico deve ser dispendida atenção especial às instruções passadas ao paciente e também fazer o possível para motivar e encorajar o seu engajamento na rotina de higienização, além do acompanhamento periodontal, possíveis substituições de parafusos e instalação de placa oclusal estabilizadora, quando necessário. Manter uma higiene oral adequada é essencial para o sucesso das próteses fixas sobre implantes e o cirurgião dentista desempenha um papel crucial não apenas ao realizar o acompanhamento periódico do paciente, mas também ao sugerir os instrumentos mais apropriados, instruir sobre a higiene oral adequada e motivar o paciente a manter a saúde bucal satisfatória(AU)


The evolution of treatments in implantology has enable a change in rehabilitation treatments for edentulous patients, making it possible to place fixed prostheses that provide a better quality of life for these patients. In order to ensure good performance and satisfactory longevity, it is essential to maintain an appropriate standard of oral hygiene and professional maintenance. Thus, the objective of this work was to conduct a literature review on the main resources available for cleaning and maintenance of complete fixed prostheses on implants (Branemark protocol), both in the patients' home care and in the professional care provided by the dentist. A nonsystematic electronic search was carried out in the Lilacs, Pubmed/Medline, Scielo, and ScienceDirect databases, crossing the following descriptors: "Oral Hygiene"; "Dental Implants"; "Dental Implantation"; "Maintenance"; "Dental Prosthesis, ImplantSupported"; and "Prosthodontics". Literature review articles, systematic reviews, meta-analyses, randomized clinical studies, and relevant books on the subject published from 1995 to 2022 were consulted. The literature available indicates that the main instruments recommended for home care are toothbrush, dental floss, interdental brush, oral irrigator, toothpaste, and mouthwash. In the professional dental office, special attention should be given to the instructions given to the patient, as well as to motivate and encourage their engagement in the hygiene routine, in addition to periodontal monitoring, possible screw replacements, and installation of an occlusal splint when necessary. Maintaining adequate oral hygiene is essential for the success of fixed prostheses on implants, and the dentist plays a crucial role, not only in providing periodic patient follow-up, but also in suggesting the most appropriate instruments, instructing on adequate oral hygiene, and motivating the patient to maintain satisfactory oral health(AU)

ABSTRACT

Este artigo tem como objetivo avaliar o acesso à prótese dentária na Atenção Primária em Saúde (APS) no Brasil. É um estudo transversal, em que foram utilizados dados do Programa de Melhoria do Acesso e da Qualidade Atenção Básica (PMAQ-AB), segundo e terceiro ciclos, com enfoque em saúde bucal e atendimento à prótese dentária por estado brasileiro. Ao comparar as Unidades Básicas de Saúde (UBS) que fazem instalações de prótese nos dois ciclos de avaliação, foi observada diferença estatisticamente significativa (teste Mann Whitney, p = 0,04), mostrando maior número de instalações no terceiro ciclo. O percentual de UBS que instalavam prótese dentária no segundo ciclo foi de 8,4% e no terceiro ciclo, 14,1%. Ao se avaliar os locais em que os pacientes fizeram a prótese dentária, verifica-se que a maioria fez suas próteses no serviço privado. Conclui-se, então, que a APS não consegue suprir a demanda por prótese dentária.


This cross-sectional study evaluates access to dental prosthesis in Primary Health Care (PHC) in Brazil. Data were obtained from the Access and Quality Improvement Program (PMAQ-AB), second and third cycles, focusing on oral health and dental care provided by the Brazilian State. Comparison of the Basic Health Units (BHU) that perform prosthesis installations in the two evaluation cycles (Mann Whitney test, p = 0.04) revealed a statistically significant difference, showing a greater number of installations in the third cycle. In the second and third cycles 8.4% and 14.1% of UBS, respectively, installed dental prostheses. When evaluating where patients acquired their dental prosthesis, most sought the private service. In conclusion, PHC cannot meet the demand for dental prosthesis.

ABSTRACT

ABSTRACT In this article, we present the case of a 47-year-old man who underwent Bentall-Bono procedure and frozen elephant trunk prosthesis implantation due to severe aortic regurgitation and aortic dilatation with a second-time endovascular stent-graft repair in descending aorta. Over eight years, a subacute graft infection by Propionibacterium acnes was developed, culminating in cardiogenic shock secondary to severe aortic regurgitation due to a complete aortic root dehiscence because of multiple aortic pseudoaneurysms. The patient underwent emergency surgery in which the replacement of the graft by a biological valve tube was performed accompanied by a complete debranching of the three supra-aortic vessels.

ABSTRACT

Aim: This study aimed to investigate the relationship between self-perceived oral health and the prosthetic status of individuals who seek care in prosthodontics clinics. Methods: Self-perceived oral health was analyzed through the Geriatric Oral Health Assessment Index (GOHAI). Abutment tooth mobility was assessed, and denture status was determined by clinical assessment of stability, retention, occlusal balance, vertical dimension, and integrity of dentures. The frequency of individuals in each variable was determined for the low and very low GOHAI conditions. Chi-square, Pearson, and stepwise logistic regression tests were used for the statistical analyses (α = 0.05). Results: Ninety wearers of removable dentures with a mean age of 55.1±9.1 years were evaluated. None of the variables was related to GOHAI values (p > 0.05). The regression analysis showed that age predicts (p = 0.006) the variation of GOHAI conditions (OR = 0.924, CI = 0.873- 0.978), showing only 7.6% protective effect against very low GOHAI. Unsatisfactory stability showed the opposite effect (p = 0.034) and the individuals with this characteristic are more likely (OR = 3.055) to have very low GOHAI scores (CI = 1.085- 8.602). Conclusions: The self-perceived oral health of wearers of removable dentures worsens with age and unsatisfactory stability of dentures

ABSTRACT

Objective: To explore the social and clinical factors that predict audiometric outcomes in patients undergoing ossicular chain reconstruction. Methods: A retrospective analytical cohort study was conducted, including patients 18 years of age or older with a history of chronic otitis media (COM) and/or any of its complications, who underwent ossicular chain reconstruction with Partial Ossicular Replacement Prosthesis (PORP) or Total Ossicular Replacement Prosthesis (TORP), at Hospital San José and Hospital infantile Universitario de San José between 2012 and 2020. We excluded patients with ossicular chain malformations and those with incomplete information. Information about sociodemographic and clinical factors was collected. Additionally, the surgery findings information was analyzed using the Ossiculoplasty outcome parameter staging ( OOPS) index. Results: A total of 35 adult patients who underwent ossicular chain reconstruction were retrospectively studied. An improvement was evidenced in the Preoperative Pure-Tone Average (PTA) and postoperative PTA (p-value=0.036), as well as in the pre and postoperative air-bone gap (ABG) (p-value < 0.01). A moderate correlation coefficient was found between the OOPS index and the postoperative PTA (p= 0.429), and between the OOPS index and the postoperative (ABG) (p= 0.653). Conclusion: We found that a higher OOPS score is correlated with worse hearing outcomes postoperatively, and there was no association between the demographic or pathologic factors with a worse postoperative hearing outcome. Therefore, OOPS index can predict audiometric outcomes in patients undergoing ossicular chain reconstruction in a developing country, regardless of the demographic or pathologic factors.


Objetivo: Evaluar los factores sociales y clínicos que predicen los desenlaces audiométricos en pacientes llevados a reconstrucción de cadena osicular en un país envía de desarrollo. Métodos: Se realizo un estudio de cohorte analítico retrospectivo donde se incluyeron pacientes mayores de 18 años, con antecedente de otitis media crónica y/o alguna complicación/secuela de esta, que fueron llevados a reconstrucción de la cadena osicular con prótesis PORP - TORP de la Fundación Universitaria de Ciencias de la Salud entre el año 2012 y 2020, se excluyeron pacientes con malformaciones de la cadena osicular y aquellos con informacion incompleta de su historia clinica y quirurgica. Resultados: La población estudiada fue 35 pacientes, en los cuales se compararon variables demográficas, antecedentes de rinitis o tabaquismo activo, parámetros audiológicos pre y postoperatorios, y hallazgos intraquirurgicos. Se evidenció una diferencia estadísticamente significativa entre el promedio tonal auditivo (PTA) preoperatorio y el PTA postoperatorio (p-valor=0.036), así como en el gap aéreo- oseo pre y post operatorio ( p-valor < 0.01). Se reportó un coeficiente de correlación moderado entre el índice OOPS y el PTA post operatorio (p = 0.429), y entre el índice OOPS y el gap aéreo óseo post operatorio (p = 0.653), lo que indica que a mayor puntaje en el índice OOPS peores desenlaces auditivos. Conclusión: En este estudio un mayor puntaje en el índice OOPS se correlacionó con peores desenlaces auditivos. No se evidenció correlación entre los factores demográficos u otras comorbilidades descritas y un peor desenlace auditivo post operatorio. Aunque se obtuvo un GAO postoperatorio ≤20dB en el 48.5% de los pacientes, se observó una disminución en el GAO estadísticamente significativo.

ABSTRACT

ABSTRACT Due to the development of complications and the biocompatibility and scarcity of transplant donor tissues, artificial corneas, which can be used for the rehabilitation of optical functions, have been developed. The current study aimed to analyze the visual rehabilitation effects of the Boston type I keratoprosthesis, Boston type II keratoprosthesis, Aurolab keratoprosthesis, osteo-odonto-keratoprosthesis, and tibial bone keratoprosthesis. Results showed that the Boston type I keratoprosthesis was the most effective for visual rehabilitation in patients with moist ocular surfaces. The Aurolab keratoprosthesis had a lower efficacy for visual rehabilitation. Nevertheless, it is still a viable option for individuals in economically restricted countries. In patients with dry eyes, the Boston type II keratoprosthesis was associated with the best visual rehabilitation. However, the final visual acuity of patients who received osteo-odonto-keratoprosthesis and tibial bone keratoprosthesis implantation was not evaluated as the necessary information was not available.


RESUMO Em decorrência de complicações, da biocompatibilidade e da escassez de tecido doador para transplantes de córnea natural, foram elaboradas córneas artificiais que são potenciais para reabilitar funções ópticas. Nessa perspectiva, objetivou-se a análise da eficácia da reabilitação visual entre os implantes: Boston tipo I, Boston tipo II, Aurolab, osteo-odonto-ceratoprótese e ceratoprótese de Osso Tibial. De modo geral, a princípio observou-se uma tendência de melhoria da Best-corrected visual acuity em todos os tipos de lentes, mas considerável queda durante acompanhamento a longo prazo. O dispositivo com melhor reabilitação visual em pacientes com superfícies oculares úmidas é a Boston tipo I, seguida pela Aurolab, que é economicamente viável em países emergentes. Ao considerar pacientes com olhos secos, o implante de Boston tipo II apresenta maior reabilitação visual. Por fim, em virtude de não apresentarem dados equiparáveis, as lentes osteo-odonto-ceratoprótese e de osso tibial não puderam ser analisadas.

ABSTRACT

Aim: This study aimed to review the scientific literature to describe the main care and hygiene protocols for different types of maxillofacial prostheses (MFP). Methods: A bibliographic search on the PubMed / Medline database using the following keywords: ["maxillofacial prosthesis" OR "ocular prostheses" OR "palatal obturators"] AND ["Cleaning" OR "disinfection"] AND ["care"] AND ["color stability"] OR ["denture cleansers" OR "cleansing agents"]. Articles addressing materials, cleaning and disinfection protocols, and care related to MFP were included. The following exclusion criteria were applied: no adequate methodology, incompatibility with the area of interest, and unavailability for reading in full. Results: The papers were grouped into the following topics: facial prostheses, ocular prostheses, maxillofacial intraoral prostheses, and retention systems. Conclusion: Despite the MFP changes over time, its degradation decreases upon following the recommendations and post-adaptation care. The guidelines for cleaning and disinfection must be individualized to guarantee the longevity of the prosthesis and the patient health

ABSTRACT

Aim: The main purpose of this study was to conduct a narrative review investigating the possible relationship between permanent maxillary anterior teeth and anthropometric facial parameters in different populations. Methods: Searches were performed in the PubMed, BVS (Biblioteca Virtual em Saúde) and SciELO databases to identify relevant scientific articles using the following search terms: "maxillary anterior teeth", "facial measurements" and "anthropometry", in such a way that 218 publications were found. After application of inclusion and exclusion criteria, 13 publications remained for full-text reading. Results: All studies involved male and female samples and it was notorious that male measurements were unanimously higher than those obtained in the opposite sex. The age of the analyzed participants ranged from 17 to 60 years; however, a mean age of 18 to 25 years was the most investigated in literature. In addition, facial measurements including the bizygomatic width, interpupillary distance, intercanthal distance, interalar width and intercommissural width have been proposed to help determine the correct size of anterior teeth. Conclusion: It was concluded that despite the limited number of studies, some factors that influence dental and facial dimensions, such as sex and age, can be identified. However, there is no standardization of the facial or dental parameters used in the studies, a fact that makes it difficult to establish a universal ratio for clinical dental practice

ABSTRACT

Abstract Background Chronic mesenteric ischemia (CMI) is a debilitating disease with a heavy burden on quality of life. Stenting of the superior mesenteric artery (SMA) is the first option for treatment, but there is a lack of consensus defining precise indications for open revascularization (OR). Objectives To describe a series of 4 patients with CMI treated with OR and to present an algorithm for the management of this condition. Methods Three patients presented with typical intestinal angina and weight loss. One patient was subjected to prophylactic revascularization during open abdominal aortic aneurysm repair. Surgical techniques included: 1) Bypass from the infrarenal aorta to the SMA; 2) Bypass from an aorto-bifemoral polyester graft to the SMA; 3) Bypass from the right iliac artery to the SMA; 4) Bypass from the right graft limb of an aorto-biiliac polyester graft to the median colic artery at Riolan's arcade. PTFE was used in all surgeries. All grafts were placed in a retrograde configuration, tunneled under the left renal vein, making a smooth C-loop. A treatment algorithm was constructed based on the institution's experience and a review of recent literature. Results All patients demonstrated resolution of symptoms and recovery of body weight. All grafts are patent after mean follow-up of two years. Conclusions Open revascularization using the C-loop configuration is a valuable technique for CMI and may be considered in selected cases. The algorithm constructed may help decision planning in other quaternary centers.


Resumo Contexto A isquemia mesentérica crônica (IMC) é uma doença debilitante, com grave impacto na qualidade de vida. A literatura recomenda a angioplastia com stent da artéria mesentérica superior (AMS) como primeira opção de tratamento, mas há falta de consenso que defina indicações precisas para a revascularização aberta. Objetivos Descrever uma série de quatro pacientes com IMC, tratados com revascularização aberta, e apresentar um algoritmo para o manejo dessa condição. Métodos Três pacientes apresentaram angina intestinal típica e perda ponderal. Uma paciente foi submetida a reparo aberto de aneurisma da aorta abdominal e apresentava obstrução da AMS, que foi revascularizada profilaticamente. As técnicas cirúrgicas incluíram: 1) enxerto entre a aorta infrarrenal e a AMS; 2) enxerto entre o dácron utilizado em um enxerto aortobifemoral e a AMS; 3) enxerto entre a artéria ilíaca comum direita e a AMS; e 4) enxerto entre o ramo direito do dácron utilizado em um enxerto aorto-biilíaco e a artéria cólica média (ao nível da arcada de Riolan). Todos os enxertos foram feitos utilizando politetrafluoretileno em uma configuração retrógrada, tunelizados abaixo da veia renal esquerda, fazendo uma alça em C. Resultados Todos os pacientes demonstraram resolução dos sintomas e ganho ponderal. Todos os enxertos se mantiveram pérvios durante um seguimento médio de 2 anos. Conclusões A revascularização aberta para IMC utilizando-se a alça em C é uma técnica valiosa e pode ser considerada em pacientes selecionados. O algoritmo proposto pode auxiliar na decisão terapêutica em centros quaternários.

ABSTRACT

A Prótese bucomaxilofacial (PBMF) é a especialidade da Odontologia que reabilita proteticamente pacientes com perda de estrutura na região da face. Entende-se por PBMFs aquelas utilizadas na reabilitação de pacientes que apresentam deformidades por etiologia congênita, traumática ou patológica. Objetivo: Avaliar retrospectivamente o perfil dos pacientes bem como as características das reabilitações protéticas realizadas em um Projeto de Extensão em Prótese Bucomaxilofacial de uma Universidade no sul do Brasil.Materiais e métodos:Foram analisados 90 prontuários de pacientes atendidos no período de agosto de 2017 a dezembro de 2018, e coletados os seguintes dados: gênero, cor/etnia, idade, etiologia da deformidade, tipo de prótese reabilitadora realizada e referenciamento do paciente ao Projeto. Resultados:Observou-se que pacientes do gênero masculino e cor branca foram os mais frequentemente reabilitados com a maioria dos tipos de prótese, com exceção da prótese nasal. A idade dos pacientes variou de 5 a 81 anos. A prótese ocular foi a mais confeccionada. A etiologia patológica foi a que mais exigiu tratamento reabilitador. Médicos e equipes hospitalares foram os que mais referenciaram pacientes para o Projeto de Extensão.Discussão: A maior prevalência de atendidos foi de pacientes do gênero masculino, etiologia patológica, com idade 60 anos ou mais, o que reforça a sobrevida das pessoas que são diagnosticadas com câncer e necessitam reabilitação bucomaxilofacial. Conclusão: A grande procura por atendimento no Projeto de Extensão em PBMF mostra uma carência desse serviço e poucas pesquisas para esclarecer o perfil do paciente que mais procura atendimento PBMF.


Bucomaxillofacial Prosthesis (BMFP) is a specialty of Dentistry that rehabilitates patients with loss of structure in the face region. BMFP are known to be used in the rehabilitation of patients who present deformities due to congenital, traumatic or pathological etiology. Aim:In retrospect, to assess the profile of patients, as well as the features of clinical cases of rehabilitations performed at the Buccomaxillofacial Prosthesis Extension Project, at the Faculty of Dentistry of the Universidade Federal do Rio Grande do Sul, UFRGS. Materials and methods:from August 2017 to December 2018, 90 charts were cataloged with the following data: gender, ethnicity, age, etiology of the deformity, type of rehabilitation prosthesis, how the patient came to the Project. Results:It was concluded that white male patients were the predominant group to be benefited with prosthesis. The age gap was from 5 to 81 years. Ocular prosthesis was the most prevalent one. The pathological etiology was the one that most required rehabilitation treatment. Doctors and hospital staff were the ones who most referred patients to the Project.Discussion:The prevalence of patients attended was male, pathological etiology, aged 60 years or more, which reinforces the survival of people who are diagnosed with cancer and need oral and maxillofacial rehabilitation. Conclusion:The great demand for care in the BMFP Extension Project shows a lack of this service and little research to clarify the profile of the patient who most seeks BMFP care.

ABSTRACT

La tecnología CAD/CAM es una forma innovadora relacionada con la implementación de técnicas digitales para mejorar las restauraciones prostéticas en un paciente, entre ellas, las destinadas a la estética dental. El presente estudio tiene el objetivo de describir la utilidad de la tecnología CAD/CAM en la fabricación de prótesis dentales. Para ello se realizó una revisión de la literatura médica disponible en las bases de datos PubMed/Medline, Scopus y SciELO, mediante fórmulas de búsqueda avanzada; se seleccionaron artículos en idioma español e inglés. En la actualidad, con esta tecnología se ha logrado combinar estética, resistencia y precisión en la restauración directa, además de garantizarse una mayor duración y años de funcionalidad para cada una de las prótesis, coronas e implantes. La calidad de vida y satisfacción referidas por los pacientes portadores de piezas producidas con esta tecnología, es superior a las manifestadas por aquellos tratados con piezas de fabricación tradicional. El uso de técnicas de inteligencia artificial y biomateriales representará un cambio cualitativo y cuantitativo en el uso de los sistemas CAD/CAM.


CAD/CAM technology is an innovative way related to the implementation of digital techniques to improve prosthetic restorations in a patient, including those intended for dental aesthetics. The objective of this study is to describe the usefulness of CAD/CAM technology in the dental prostheses manufacture. A review of the medical literature available in the PubMed/Medline, Scopus and SciELO databases was carried out, using advanced search formulas; Articles in Spanish and English were selected. Currently, with this technology it has been possible to combine aesthetics, resistance and precision in direct restoration, in addition to guaranteeing greater duration and years of functionality for each of the prostheses, crowns and implants. The quality of life and satisfaction reported by patients wearing parts produced with this technology is higher than those reported by those treated with traditionally manufactured parts. The use of artificial intelligence and biomaterials techniques will represent a qualitative and quantitative change in the use of CAD/CAM systems.

ABSTRACT

Introducción: La rehabilitación cardiaca en pacientes con prótesis valvular es esencial para aumentar su sobrevida e incorporarlos óptimamente a la sociedad. Objetivo: Caracterizar a pacientes con prótesis valvular mecánica y rehabilitación cardiovascular. Métodos: Se realizó un estudio observacional, descriptivo, de serie de casos, de 70 pacientes con prótesis valvular mecánica, admitidos en el programa de rehabilitación cardiovascular del Hospital General Universitario Vladimir Ilich Lenin de la provincia de Holguín, desde marzo del 2019 hasta noviembre del 2022. Resultados: Predominaron los pacientes de 55 a 64 años de edad (38,6 %), con prótesis en posición mitral, sin complicaciones. En los sujetos rehabilitados se observó una reducción de la media de hipercolesterolemia (de 250 a 175 mg/dL) y un aumento de la capacidad funcional por la duración del ejercicio, así como de las unidades metabólicas consumidas. La media de la función ventricular izquierda tras la terapia rehabilitadora se incrementó de 52,4 a 58,2 %. Solo 2 afectados necesitaron rehospitalización e incorporar más fármacos a su tratamiento basal y 50 retornaron a sus actividades laborales. El resultado fue satisfactorio en 97,1 % de los integrantes de la serie. Conclusiones: Esta terapia resultó beneficiosa, pues se incrementó la capacidad funcional de los pacientes y fueron pocas las complicaciones. Los factores de riesgo coronarios estuvieron controlados, se redujo la rehospitalización y aumentó la reincorporación laboral.


Introduction: Heart rehabilitation in patients with valvular prosthesis is essential to increase their survival and incorporate them optimally to the society. Objective: To characterize patients with mechanical valvular prosthesis and cardiovascular rehabilitation. Methods: An observational, descriptive, serial cases study of 70 patients with mechanical valvular prosthesis was carried out, who were admitted to the program of cardiovascular rehabilitation of Vladimir Ilich Lenin University General Hospital in Holguín province, from March, 2019 to November, 2022. Results: There was a prevalence of 55 to 64 years patients (38.6%), with prosthesis in mitral position, without complications. In the rehabilitated patients a reduction of the mean in hypercholesterolemia was observed (from 250 to 175 mg/dL) and an increase of the functional capacity due to the duration of exercise, as well as of the consumed metabolic units. There was an increase from 52.4 to 58.2% in the mean of the left ventricular function after the rehabilitative therapy. Only 2 affected patients needed rehospitalization and to incorporate more medication to their basal treatment and 50 returned to their working activities. The result was satisfactory in 97.1% of the series members. Conclusions: This therapy was beneficial, because there was an increase of the functional capacity of patients and complications were not very common. The coronary risk factors were controlled; there was a reduction of rehospitalization and an increase of working reincorporation.

ABSTRACT

A utilização da tecnologia CAD/CAM (computer aided design/computer aided manufacturing) e 3D (tridimensional) para reconstruções alveolares na implantodontia permite o planejamento pré-operatório detalhado, o design do resultado desejado do enxerto e a avaliação virtual do resultado em relação à reconstrução protética. Este trabalho objetiva detalhar a técnica cirúrgica de enxerto ósseo sintético confeccionado por meio dessa tecnologia, seguido da instalação de implantes osseointegráveis e reabilitação protética em um defeito ósseo na mandíbula. Paciente masculino, 22 anos, compareceu à clínica por avulsão dos elementos 32, 31, 41 e 42 com significativa perda óssea vertical de rebordo alveolar. Devido à extensa perda óssea, realizou-se enxerto em bloco prototipado impresso. O escaneamento intraoral e os arquivos de imagem gerados foram enviados ao centro de planejamento virtual. Primeiramente, foi realizada a cirurgia para instalação do enxerto em bloco. Após o período de cicatrização, foi realizada cirurgia para instalação de dois implantes osseointegráveis. Esperado o período de três meses a partir da instalação dos implantes, foi realizada a confecção de próteses provisórias fixas sobre implantes a fim de realizar o condicionamento dos tecidos moles peri-implantares e o carregamento progressivo dos implantes. O aumento do rebordo alveolar através do uso de enxerto em bloco impresso personalizado apresentou-se como uma técnica com inúmeras vantagens, por não necessitar de sítio doador, reduzir tempo cirúrgico e apresentar perfeita adaptação do bloco ao defeito ósseo, resultando em menor morbidade pós-operatória. Essa técnica é uma indicação para casos de defeitos ósseos severos, visando a otimizar o resultado e a propiciar menor desconforto ao paciente.


The use of the technology CAD/CAM (computer aided design/computer aided manufacturing) and 3D (three dimensional) to alveolar reconstructions in implant dentistry allows detailed preoperative planning, the design of the desired grafting result, and the virtual evaluation of the result in relation to the prosthetic reconstruction. This paper aims to details the synthetic bone graft made through this technology, followed by the installation of osseointegrated implants and prosthetic rehabilitation in a bone imperfection in the jaw. A 22-year-old man attended the clinic due to a tooth avulsion of the four lower incisors with significant vertical bone loss of alveolar ridge. Because of the extensive bone loss, it was made a prototyped printed block graft. The intraoral scan and the generated image files were sent to the virtual planning center. First, it was necessary a surgery to install the block graft. After the healing process, it was made a surgery to put two osseointegrated implants. Three months later, temporary fixed prostheses on implants were made to conditioning the peri-implant soft tissues and the progressive loading of the implants. The increase of the alveolar ridge using personalized printed block graft was presented as a technique with numerous advantages, since it does not require a donor site, reduces the surgical time and presents perfect adaptation of the block to the bone imperfection, resulting in a less postoperative morbidity. This technique is indicated to cases of severe bone imperfections, aims to optimize results, and provide less discomfort to the patient.

ABSTRACT

Abstract Background: The use of pancreatic prostheses in children with acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) has evolved. The main established indication is the treatment of persistent abdominal pain. This study aimed to evaluate the efficacy of pancreatic stenting for refractory abdominal pain in pediatric patients with ARP and CP. Methods: We conducted a retrospective case series study. We included patients under 16 years of age diagnosed with ARP and CP in the study. Endoscopic retrograde cholangiopancreatography (ERCP) was performed with the insertion of one and later two pancreatic stents. We evaluated abdominal symptoms before and after treatment, number of changes, duration of treatment, and complications with follow-up at 24 months and after withdrawal. Results: Nine patients with ARP and CP were included in the study: six with undetermined etiology and three with pancreas divisum. The mean age was 12.4 years. Prosthesis placement relieved abdominal pain in 100% of cases, with 3.2 replacement sessions every 6.2 months for 27.4 months, and mild complications (15.7%). One patient experienced pain on removal of the prosthesis and required bypass surgery. Conclusion: Pancreatic stent placement in patients with refractory abdominal pain with ARP and CP proved to be effective and safe, providing medium-term symptom relief and minimal complications.


Resumen Introducción: El uso de prótesis pancreáticas en niños con pancreatitis aguda recurrente (PAR) y crónica (PC) ha evolucionado. La principal indicación establecida es el tratamiento del dolor abdominal persistente. El objetivo de este estudio fue evaluar la eficacia del uso prótesis pancreática para el dolor abdominal refractario en pacientes pediátricos con PAR y PC, sin respuesta a manejo conservador. Métodos: Se llevó a cabo un estudio retrospectivo de serie de casos. Se incluyeron pacientes menores de 16 años con diagnóstico de PAR y PC. Se realizó una colangio pancreatografía retrograda endoscópica (CPRE) para introducir inicialmente una y posteriormente dos prótesis pancreáticas. Se evaluaron síntomas abdominales antes y después del tratamiento, número de recambios, duración del tratamiento y complicaciones con seguimiento a 24 meses y posterior a su retiro. Resultados: Se incluyeron 9 pacientes con PAR y PC: seis de etiología no determinada y tres con páncreas divisum. La edad promedio fue de 12.4 años. La colocación de prótesis alivió el dolor abdominal en el 100%, con 3.2 sesiones de recambio cada 6.2 meses en 27.4 meses, y complicaciones leves (15.7%). Un paciente presentó dolor al retirar las prótesis y requirió cirugía derivativa. Conclusiones: El uso de prótesis pancreática en pacientes con dolor abdominal refractario con PAR y PC demostró ser eficaz y seguro al aliviar los síntomas a mediano plazo con mínimas complicaciones.

ABSTRACT

En la actualidad es cada vez más frecuente la consulta de pacientes que siendo sometidos en edades tempranas a cirugías de extirpación tumoral y posterior reconstrucción con injertos presentan problemas tanto funcionales como estéticos, el uso de prótesis implantosoportadas mejora la calidad de vida, pero al mismo tiempo representan un desafío por la baja disponibilidad ósea. Se presenta un caso clínico de rehabilitación protésica implantosoportada en una paciente con gran déficit óseo mandibular como consecuencia de le extirpación de una neoplasia y posterior injerto de costilla. Se colocaron 2 implantes osteointegrados en hueso remanente y rehabilitación con prótesis removible sostenida a una barra colada. Por ser un tratamiento poco invasivo y conservador fue aceptado fácilmente por la paciente y la mejora tanto en la estética como en la función fue notoria.


Nowadays, it is becoming more and more frequent to see patients who underwent surgery for tumor removal and subsequent reconstruction with grafts at an early age, presenting both functional and esthetic problems. The use of implant-supported prostheses improves the quality of life, but at the same time represents a challenge due to the low availability of bone. A clinical case of implant-supported prosthetic rehabilitation is presented in a patient with a great mandibular bone deficit as a consequence of the removal of a neoplasm and subsequent rib graft. Two osseointegrated implants were placed in the remaining bone and rehabilitation with a removable prosthesis supported by a cast bar. Being a minimally invasive and conservative treatment, it was easily accepted by the patient and the improvement in both esthetics and function was notorious.


Atualmente, são cada vez mais frequentes os pacientes submetidos à cirurgia de remoção de tumores e posterior reconstrução com enxertos em idade precoce que apresentam problemas funcionais e estéticos. O uso de próteses implanto-suportadas melhora a qualidade de vida, mas, ao mesmo tempo, representa um desafio devido à baixa disponibilidade de osso. Apresentamos um caso clínico de reabilitação protética implanto-suportada em um paciente com grande déficit ósseo mandibular em consequência da remoção de uma neoplasia e posterior enxerto de costela. Dois implantes osseointegrados foram colocados no osso remanescente e a reabilitação foi feita com uma prótese removível suportada por uma barra de gesso. Por se tratar de um tratamento minimamente invasivo e conservador, foi facilmente aceito pelo paciente e a melhora na estética e na função foi perceptível.

ABSTRACT

Abstract Objective The present study aimed to compare the cure rate recovery time and Merle d'Aubigné-Postel functional (MAPF) score after single-stage surgery (C1T) or two-stage surgery (C2T) to treat prosthetic infections of the hip considering sociodemographic and clinical features of the patients. Materials and Methods The present retrospective study occurred in a single center from 2011 to 2014 with 37 studied cases including 26 treated with C1T and 11 with C2T. We compared the cure rate recovery time and MAPF score in the two groups as well as the sociodemographic and clinical features of the patients. We also considered surgical complications and the most common infectious agents. Results The C1T group had a faster functional recovery than the C2T group but there were no significant differences in the cure rate surgical complications or MAPF score. However C1T group patients were significantly younger which may have influenced the outcomes. Staphylococcus spp. was the most common infectious agent (62%). Conclusion Although C2T appears superior regarding infection cure C1T may be preferable for faster functional recovery. However it is critical to consider individual patient characteristics when choosing treatment. Further research with a larger sample size is required to confirm these results.


Resumo Objetivo Comparar a taxa de cura, o tempo de recuperação e a pontuação na escala funcional de Merle d'Aubigné-Postel (EFMA) entre a cirurgia em tempo único (C1T) e a cirurgia em dois tempos (C2T) no tratamento de infecções protéticas do quadril, considerando as características sociodemográficas e clínicas dos pacientes. Materiais e Métodos Foi realizado um estudo retrospectivo num único centro, entre 2011 e 2014, com um total de 37 casos estudados, sendo 26 tratados com C1T e 11 com C2T. Foram comparadas a taxa de cura, o tempo de recuperação e a pontuação EFMA entre os dois grupos, bem como as características sociodemográficas e clínicas dos pacientes. Foram também consideradas as complicações cirúrgicas e o agente infeccioso mais comum. Resultados O grupo C1T teve uma recuperação funcional mais rápida do que o grupo C2T, mas não houve diferenças significativas na taxa de cura, nas complicações cirúrgicas ou na pontuação EFMA. No entanto, o grupo C1T era significativamente mais jovem, o que pode ter influenciado os resultados. Staphylococcus spp. foi o agente infeccioso mais comum (62%). Conclusão Embora a C2T pareça ser superior em termos de cura de infecção, a C1T pode ser preferível para uma recuperação funcional mais rápida. No entanto, as características individuais dos pacientes devem ser consideradas na escolha do tratamento. São necessárias mais pesquisas com um tamanho de amostra maior para confirmar estes resultados.

ABSTRACT

Abstract Introduction Stapes surgery for otosclerosis is a precise surgical procedure. To achieve excellent hearing results, a firm and stable attachment of the prosthesis to the long process of incus (LPI) is necessary. The present study provides details on the attachment site in two dimensions to choose an appropriate prosthesis and to ensure firm attachment for better surgical outcomes. Objective To study the diameter of the LPI and its relevance in determining the piston, used in stapes surgery by an in vivo method. Methods This study was conducted in 41 patients who underwent stapedotomy, where both Anteroposterior (AP) and Mediolateral (ML) diameters of the LPI were measured at the site of attachment of the piston using specially designed instruments, intraoperatively. Radiological data were obtained to measure the LPI diameter from the normal ears of 46 patients. It was measured from both the right and left side, hence 92 LPI diameters were obtained. Results The most commonly used site for prosthesis attachment is between 1-1.5 mm away from the tip of the LPI. We found great variability in the diameters of LPI in the attachment site, with the AP diameter ranging between 0.6 -1.5mm and the ML diameter ranging between 0.5mm-1.2mm. Conclusion Pistons by design have characteristics of gripping incus that will vary between types. Based on LPI dimensions, ideal piston types with appropriate inner loop diameters are suggested in this study. HRCT before surgery should include measurements of the LPI as a guide to the choice of the prosthesis during surgery.

ABSTRACT

Abstract Objective: To analyze the association between osteolysis at the prosthesis interfaces, as determined by magnetic resonance imaging (MRI) with multiacquisition variable-resonance image combination selective (MAVRIC-SL) sequences, and clinical severity after knee or hip arthroplasty, as well as to assess interobserver and intraobserver agreement on periprosthetic bone resorption. Materials and Methods: This was a cross-sectional study of 47 patients (49 joints) under postoperative follow-up after knee or hip arthroplasty, with chronic pain, between March 2019 and August 2020. All of the patients completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. The component interfaces were evaluated and ordered into two groups: osseointegrated and osteolytic. Nonparametric tests were used. Results: There were significant differences between the two groups in terms of the mean WOMAC scores: total (p = 0.010); stiffness domain (p = 0.047); and function (p = 0.011) domains. There was substantial interobserver and intraobserver agreement for most analyses of the components. Conclusion: Periprosthetic osteolysis appears to be associated with clinical complaints of pain in the post-arthroplasty scenario, and MAVRIC-SL provides reproducible assessments. It could prove to be an important tool for orthopedists to use in the evaluation of challenging cases of chronic pain after arthroplasty.


Resumo Objetivo: Analisar associação entre osteólise nas interfaces protéticas por ressonância magnética com sequências MAVRIC-SL e a gravidade clínica dos pacientes submetidos a artroplastias de joelho ou quadril. Determinar concordância intraobservador e interobservador na reabsorção óssea peri-implante. Materiais e Métodos: Foi realizado estudo transversal entre março de 2019 e agosto de 2020, com 47 pacientes (49 articulações) em seguimento pós-operatório de artroplastias de joelho ou quadril, com dor crônica, que responderam ao questionário WOMAC. As interfaces dos componentes foram avaliadas e definiram dois grupos: osteointegrado e osteólise. Testes não paramétricos foram usados. Resultados: Houve diferença significativa na média do escore WOMAC entre os grupos (p = 0,010), assim como nos domínios rigidez (p = 0,047) e função (p = 0,011). Houve concordância substancial interobservador e intraobservador para a maioria dos componentes analisados. Conclusão: Osteólise periprótese parece estar associada com a queixa clínica de dor pós-artroplastia, com avaliação reprodutível pela MAVRIC-SL. Isto pode ser uma importante ferramenta para o ortopedista na avaliação de casos desafiadores de dor crônica pós-artroplastia.

ABSTRACT

As próteses parciais removíveis (PPRs) são uma alternativa de tratamento viável na prática clínica para reabilitar arcos parcialmente desdentados. Entretanto, o planejamento dessas próteses e preparo bucal prévio são frequentemente negligenciados. O presente artigo tem como objetivo relatar o caso clínico de uma reabilitação oral com PPRs superior e inferior após abordagem multidisciplinar, de modo a enfatizar as fases de um planejamento criterioso e de preparo prévio dos dentes pilares, visando o sucesso e a longevidade da reabilitação. Paciente do sexo masculino de 57 anos de idade compareceu à clínica da Faculdade de Odontologia de Bauru, Universidade de São Paulo, queixando-se da estética de seu sorriso e de algumas ausências dentárias. O indivíduo utilizava uma PPR provisória inferior insatisfatória e apresentava perda de dimensão vertical de oclusão (DVO). Após o exame clínico, radiográfico e estudo do caso em articulador semi-ajustável, realizou-se o planejamento com abordagens restauradoras, endodônticas, periodontais e protéticas. Após tratamento periodontal, foi realizada endodontia dos elementos 12, 15 e 47, confecção de núcleos e coroas nos dentes 12 e 15, restauração a nível gengival para apoio residual no dente 47, restaurações nos dentes 11, 13, 22, 24 e 44 e, por fim, a confecção das PPRs superior e inferior. A abordagem multidisciplinar utilizada neste caso clínico viabilizou o restabelecimento da DVO e possibilitou o sucesso da reabilitação protética(AU)


Removable partial dentures (RPDs) are a viable treatment alternative in clinical practice to rehabilitate partially edentulous arches. However, the planning of these dentures and prior oral preparation are often neglected. This article aims to report the clinical case of an oral rehabilitation with upper and lower RPDs after a multidisciplinary approach, to emphasize the phases of careful planning and prior preparation of the abutment teeth, aiming at the success and longevity of the rehabilitation. A 57-year-old male patient came to the clinic of the Bauru School of Dentistry, University of São Paulo, complaining about the esthetics of his smile and some missing teeth. The subject was using an unsatisfactory lower provisional prosthesis and had a loss of vertical dimension of occlusion (OVD). After the clinical and radiographic examination and the case study in a semi-adjustable articulator, planning was carried out with restorative, endodontic, periodontal and prosthetic approaches. After periodontal treatment, endodontics were performed on elements 12, 15 and 47, creation of cores and crowns on teeth 12 and 15, restoration at the gingival level for residual support on tooth 47, restorations on teeth 11, 13, 22, 24 and 44 and, finally, the making of the upper and lower PPRs. The multidisciplinary approach used in this clinical case enabled the restoration of the OVD and enabled the success of the oral rehabilitation(AU)
