ABSTRACT

Objective: This study aimed to evaluate the clinical performance of two inlay-retained bridge designs (proximal shaped and inlay shaped) in single missing posterior teeth cases. Material and Methods: A total of 70 cases with missing single posterior teeth were included in this study and divided into two groups with a 1:1 allocation ratio (n = 35 for each group). Group 1 (the control group): this group received an inlay retained bridge with inlay design on both abutments. Group 2 (the intervention group): this group received an inlay retained bridge with a proximal box on both abutments. PMMA resin (YAMAHACHI PMMA) was used for the try-in stage and monolithic zirconia (Katana, Kuraray) was used for the final restorations. The restoration surfaces were treated using sandblasting and Z-prime S (Bisco) and the cementation was done by using self-adhesive resin cement (Bisco). Fracture, marginal adaptation, postoperative sensitivity, caries, and gingivitis were assessed using the modified United States Public Health Service for restoration clinical assessments (MUSPHS standards) over 12 months of follow-up. Results: The results show there was no significant difference between the two groups. Kaplan-Meier survival curve was constructed to calculate the mean survival estimates of the two groups and we found that the two groups were clinically successful during a one-year follow-up. Conclusion: Both designs of inlay retained fixed dental prostheses revealed successful clinical performance in terms of Fracture, marginal adaptation, postoperative sensitivity, caries, and gingivitis (AU)


Objetivo: O objetivo deste estudo foi avaliar o desempenho clínico de dois modelos de ponte fixa por inlay (formato proximal e formato inlay) em casos de dentes posteriores perdidos. Material e Métodos: Um total de 70 casos com perda de um único dente posterior foi incluído neste estudo e dividido em dois grupos com uma razão de alocação de 1: 1 (n = 35 para cada grupo). Grupo 1 (grupo controle): Este grupo recebeu uma ponte fixa por inlay com deseho de inlay em ambos os pilares. Grupo 2 (grupo intervenção): Este grupo recebeu uma ponte fixa inlay com uma caixa proximal em ambos os pilares. Resina de PMMA (YAMAHACHI PMMA) foi usada para a etapa de try-in e a zircônia monolítica (Katana, Kuraray) foi utilizada para as restaurações finais. As superfícies das restaurações foram jateadas com Z-prime S (Bisco) e a cimentação realizada com cimento resinoso autoadesivo (Bisco). Fratura, adaptação marginal, sensibilidade pós-operatória, cárie e gengivite foram avaliadas usando o Serviço de Saúde Pública dos Estados Unidos modificado para avaliações clínicas de restauração (padrões MUSPHS) ao longo de 12 meses de acompanhamento. Resultados: Os resultados mostraram que não houve diferença significativa entre os dois grupos. A curva de sobrevida de Kaplan-Meier foi construída para calcular as estimativas de sobrevida média dos dois grupos e foi concluído que os dois grupos foram clinicamente bem-sucedidos durante um acompanhamento de um ano. Conclusão: Ambos os modelos de próteses dentárias fixas de inlay revelaram desempenho clínico bem-sucedido em termos de fratura, adaptação marginal, sensibilidade pós-operatória, cárie e gengivite(AU)

ABSTRACT

Abstract Objective: To determine the patients' management pattern for restorative treatment procedures at the Restorative Dentistry Clinic at the Lagos State University Teaching Hospital (LASUTH). Material and Methods: A descriptive and retrospective study design was employed to determine patients' management patterns for the restorative treatment procedures at the Restorative Dentistry Clinic at LASUTH. Treatment records of patients who attended the Restorative Clinic at the Lagos State University Hospital, Ikeja, Lagos, Nigeria, from 2011 to 2014 were reviewed; the effective treatments during the period under review were recorded as treatment procedures and were recorded as operative, endodontic, fixed prosthodontics, and removable procedures. Results: A total of 14,437 (75%) operative; 1,353 (7.0%) endodontic; and 559 (2.9%) fixed prosthodontics and 2,852 (14.9%) removable prosthodontic procedures were carried out during the period under review. This study showed that operative procedures were the most performed restorative procedures, whereas removable prosthodontics and endodontic procedures ranked second and third, respectively, to operative procedures. Fixed prosthodontics procedures were the least performed restorative procedures. Conclusion: This study showed that more efforts were being expended by dentists on operative services compared to endodontic, removable, and fixed prosthodontics services combined. Comprehensive studies, embracing all disciplines of dentistry, should be carried out to determine the level of demand and clinical relevance of procedures in clinical dental practice and hence to set specific and general objectives of dental education for the populace. Access to dental health Insurance services should also be increased in the country.

ABSTRACT

Introducción: Gracias a su eficiencia y al uso exclusivo de cerámicas libres de metal, en rehabilitación oral se ha logrado alcanzar los estándares estéticos y mecánicos, manteniendo o, incluso, superando, la calidad de los tratamientos en comparación con las restauraciones metal cerámicas tradicionales. Actualmente los mecanismos de confeccion de cerámica libre están evolucionando cada vez mas hacia las tecnologías maquinadas CAD-CAM y disminuyendo su producción mediante la técnica de Inyeccion PRESS. Objetivo: Comparar la tasa de supervivencia de prótesis fija unitaria realizadas con cerámicas feldespáticas convencionales y reforzadas con disilicato de litio, confeccionadas con sistema CAD/CAM de CEREC® chair-side, en comparación con el método de inyección de laboratorio PRESS convencional de prensión. Métodos: Revisión sistemática realizada a través de búsqueda de evidencia científica en PubMed, PubMed Clinical Queries, Epistemónikos, Tripdatabase, Cochrane Library, recursos electrónicos de la Universidad de los Andes y bibliografía retrógrada, de artículos publicados hasta el año 2019. Se incluyeron todos aquellos estudios referentes a prótesis fija unitaria de cerámicas feldespática convencional y feldespática reforzada con disilicato de litio, confeccionadas mediante CAD/CAM y/o método convencional. Resultados: Un total de 28 artículos cumplieron los criterios de inclusión: 21 estudios observacionales de cohorte, 4 ensayos clínicos aleatorizados y 3 no aleatorizados. A corto y mediano plazo, CAD/CAM de CEREC® registró tasas de supervivencia de 98 por ciento y 91,9 por ciento, respectivamente. El sistema convencional registró tasas de supervivencia de 97,5 por ciento a corto plazo y 93 por ciento a mediano. Conclusiones: A corto plazo se describe en la literatura que CAD/CAM de CEREC® tuvo una tasa de supervivencia ligeramente superior al sistema convencional. Por otro lado, a mediano plazo CAD/CAM de CEREC® presentó una leve disminución respecto al sistema convencional. Aún no hay estudios disponibles para determinar la supervivencia clínica de los tratamientos a largo plazo(AU)


Introduction: Thanks to its efficiency and the exclusive use of metal-free ceramics, in oral rehabilitation it has been possible to achieve aesthetic and mechanical standards, maintaining or even exceeding the quality of the treatments compared to traditional metal-ceramic restorations. Currently, free ceramic manufacturing mechanisms are increasingly evolving towards CAD-CAM machined technologies and decreasing their conventional production through the PRESS Injection technique. Objective: Compare the survival rate of single-unit fixed prostheses made with conventional feldspathic ceramics and reinforced with lithium disilicate by the CEREC® CAD/CAM chairside system, with the conventional PRESS laboratory injection method. Methods: A systematic review was conducted of scientific evidence included in papers published until the year 2019 in PubMed, PubMed Clinical Queries, Epistemonikos, Tripdatabase, Cochrane Library, electronic resources of Los Andes Peruvian University, and retrograde bibliography. The papers selected dealt with conventional and lithium-disilicate reinforced feldspathic ceramic single-unit prostheses made by CAD/CAM and/or the conventional method. Results: A total 28 papers met the inclusion criteria. Of these, 21 were observational cohort studies, four were randomized clinical assays and three were non-randomized assays. Short- and mid-term, CEREC® CAD/CAM achieved survival rates of 98 percent and 91.9 percent, respectively. The conventional system achieved survival rates of 97.5 percent short-term and 93 percent mid-term. Conclusions: As described in the literature, CEREC® CAD/CAM had a slightly higher survival rate than the conventional system in the short term. In the medium term, however, CEREC® CAD/CAM displayed a slight reduction in comparison with the conventional system. No studies are available to determine the clinical survival of the treatments in the long term(AU)

ABSTRACT

Objective: When provisional acrylic crowns are used for a long time, they become more susceptible to marginal leakage by cariogenic bacteria. The objectives of this pilot clinical study were to compare cement based on zinc oxide-eugenol and calcium hydroxide by contamination with Streptococcus mutans, and calculate the sample size for the continuation of this study. Methods: Individuals receiving provisional crowns and following inclusion/exclusion criteria, were randomly distributed into 2 groups: zinc oxide-eugenol (n=8); calcium hydroxide (n=9). The temporary crowns were made by a blind researcher and cemented by another. Patients were also blinded by the cement used inside their crowns. After 2 months, a cement sample from the crowns' peripheral inner face was collected, placed in a tube containing 1 mL of sterile saline, serially diluted, plated on Mitis Salivarius Bacitracin agar, and incubated for 48 hours. Colony-forming units (CFU/mL) were counted. A statistical power analysis was performed to calculate sample size (1-ß=80%) and the Mann Whitney test to compare both cements (α=0.05). Results: Both cements were contaminated with S. mutans, with an average of 166.6 x 102 CFU/mL for calcium hydroxide and 435.3 x 102 CFU/mL for zinc oxide-eugenol, with no significant difference (p=0.311). The sample size calculated for this study was 36 per group. Conclusion: This pilot study suggests that there is important contamination inside provisional crowns used for two months, independent of the cement. The continuation of this study is needed, with a bigger sample size, to enable a comparison between the cements.


Objetivo: Quando coroas dentais provisórias são utilizadas por um longo período, elas se tornam susceptíveis à infiltração marginal por bactérias cariogênicas. O objetivo deste estudo clínico piloto foi comparar os cimentos a base de óxido de zinco e eugenol e hidróxido de cálcio pela contaminação com Streptococcus mutans e calcular o tamanho amostral para continuação deste estudo. Métodos: Indivíduos recebendo coroas provisórias e seguindo critérios de inclusão/exclusão, foram distribuídos aleatoriamente em dois grupos: óxido de zinco e eugenol (n=8); hidróxido de cálcio (n=9). As coroas provisórias foram feitas por um pesquisador cego e cimentadas por outro. Os pacientes também foram cegos quanto ao cimento utilizado dentro de suas coroas. Depois de 2 meses, amostras de cimentos foram coletadas da face interna periférica das coroas, colocadas em um tubo contendo 1 mL de solução salina estéril, diluídas de forma seriada, plaqueadas em ágar Mitis Salivarius Bacitracina e incubadas por 48 horas. Unidades formadoras de colônias (UFC/mL) foram contadas. Um teste de poder estatístico foi realizado para calcular o tamanho amostral (1-ß=80%) e o teste de Mann Whitney para comparar os dois cimentos (α=0.05). Resultados: Os dois cimentos foram contaminados com S. mutans, com uma média de 166.6 x 102 UFC/mL para o hidróxido de cálcio e 435.3 x 102 UFC/mL para o óxido de zinco e eugenol, com nenhuma diferença significativa (p=0.311). O cálculo amostral para este estudo foi 36 indivíduos por grupo. Conclusão: Este estudo piloto sugere que existe importante contaminação dentro de coroas provisórias utilizadas por 2 meses, independente do cimento. A continuação deste estudo é necessária, com maior tamanho amostral, para possibilitar a comparação entre os cimentos.

ABSTRACT

Objetivo: Presentar el uso de la cirugía guiada para la resolución quirúrgico-protética de un caso clínico con colocación de implantes de longitud estándar (>7 mm) en un maxilar inferior atrófico, sin regeneración ósea guiada. Caso clínico: Una paciente que requería terapia con implantes en sectores posteroinferiores se presentó en la Cátedra de Odontología Integral Adultos de la Facultad de Odontología de la Universidad de Buenos Aires. Primero se realizó una tomografía computarizada de haz cónico del maxilar inferior para evaluar la disponibilidad ósea. La planificación se efectuó siguiendo un protocolo digital a fin de optimizar la selección de los implantes y su instalación en función de la futura rehabilitación protética y el tejido óseo disponible. Después se escanearon ambos maxilares y el registro intermaxilar; estas imágenes ­junto con las correspondientes a la tomografía (DICOM)­ fueron importadas como archivos (STL) a un software específico de diseño para determinar digitalmente la posición 3D ideal de los implantes y diseñar una guía quirúrgica de precisión. Luego se realizó la cirugía de instalación de los implantes con la guía quirúrgica, y finalmente los implantes fueron rehabilitados por medio de coronas cemento-atornilladas. Conclusión: El uso de la cirugía guiada permitió optimizar el tejido óseo disponible para la instalación de implantes en función de la futura rehabilitación protética (AU)


Aim: To present the use of guided surgery for the prosthetic resolution of a clinical case with placement of implants of standard length (>7 mm) in an atrophic posterior mandible, with no need of bone regeneration. Clinical case: A patient who required implants in the posterior sectors of the mandible attended to the department of Odontología Integral Adultos, Facultad de Odontología, Universidad de Buenos Aires, Argentina. A dental cone beam computed tomography (CBCT scan) of the lower jaw was done to assess bone availability and was decided to perform guided surgery for accurate implant placement. Both maxillaries and intermaxillary occlusal registration were scanned and imported into files (STL) together with those of the CBCT scan (DICOM) into specific design software. Following the digital protocol using a surgical guide the implants were placed and then restored with cemented-screwed crowns. Conclusion: Guided surgery allowed planning implant placement, guided by the final position of the prosthetic restoration, and optimizing the available bone (AU)

ABSTRACT

ABSTRACT: This study evaluated patients' perceptions regarding the installation of temporary fixed partial denture (TFPD). A questionnaire developed that addressed patients' perceptions about the temporary restorations, applied to patients after concluded their treatment. Responses were analyzed by descriptive statistics and contingency tables were constructed to statistically analyze the relationship between patients' perceptions of age, gender and type of prosthesis. We interviewed 28 patients (23 female; 5 male). In the results, 53.57% of the patients reported improvement in the chewing, 3.57% of the patients reported an improvement in speech, 21.43% of patients reported improvement in both aspects and another 21.43% of patients did not report functional improvements in speech and in chewing. Regarding dental pain, 89.28% did not present. In the hygienization aspect, 46.42% of the patients had difficulty, and 25% of the patients had bleeding gum. Finally, 89.28% of the patients reported that a TFPD made it possible to predict the final treatment outcome. No statistically significant difference was found when age (p = 0.86062) and gender (p=0.41225) were correlated. However, the type of prosthesis influenced patients' perceptions of TFPDs (p = 0.01254). It is concluded that TFPD is an important step in the treatment with fixed prosthesis.

ABSTRACT

El póntico E es una alternativa de tratamiento para la pérdida prematura dental, este tipo de póntico fue publicado por primera vez en 2014 por Robert P. Korman. El diseño del póntico permite ofrecer predictibilidad en cuanto a soporte y mantenimiento de la arquitectura gingival, también promueve que el tejido vestibular migre coronalmente sobre el póntico, creando un surco gingival. Se recibió a una paciente que presentaba fragmento radicular del diente 21 y ausencia del diente 12, reborde residual atrófico (clase I según Seibert). Como plan de tratamiento, se realizó la extracción atraumática del fragmento radicular del diente 21 para retardar el colapso del reborde alveolar y se colocó injerto de tejido conectivo en la zona del diente 12 para corregir el defecto clase I de Seibert, se realizó la conformación de los nichos gingivales con electrobisturí en conjunto con la prótesis provisional y la preparación de los dientes pilares para la recepción y rehabilitación con pónticos E. Se colocó una prótesis fija de cinco unidades (dientes 13 al 23) en material núcleo de Zr y estratificada con cerámica (AU)


Pontic E is an alternative treatment for premature dental loss, this type of pontic was published for the first time in 2014 by Robert P. Korman. The design of the pontic allows to offer predictability in terms of support and maintenance of the gingival architecture, it also promotes that the vestibular tissue migrates coronally over the pontic, creating a gingival groove. A patient was received who presented a radicular fragment of tooth 21 and absence of tooth 12, atrophic residual ridge (class I according to Seibert). As a treatment plan, atraumatic extraction of the root fragment of tooth 21 was performed to delay the collapse of the alveolar ridge and connective tissue graft was placed in the area of tooth 12 to correct Seibert's class I defect, conformation was performed of the gingival niches with electrocautery in conjunction with the provisional prosthesis and the preparation of the abutment teeth for the reception and rehabilitation with pontics E. A fixed prosthesis of five units was placed (teeth from 13 to 23) of Zr core material and stratified with ceramic (AU)

ABSTRACT

ABSTRACT: Aging is a dynamic process that includes various alterations in the oral cavity, with tooth loss being the most frequent. Rehabilitative treatment may include removable or fixed prostheses and implants. The aim of this study was to describe the geometric (trajectory, ranges, areas) and kinematic (speed) characteristics of the mandibular and masticatory movements threedimensionally in participants with dental prostheses. A sample of 10 participants with removable prosthetic rehabilitation was divided into three groups (complete, atypical and overdenture) the characteristics of mandibular movements bordering and chewing with 3D Electromagnetic Articulography were measured. The Posselt polygonin was obtained, the frontal and sagittal plans, its areas, trajectories and ranges are analyzed. The masticatory movements were analyzed in the area of each cycle, the frequency, the speed and the reason between the masticatory cycle and the bordering movements, no significant differences between the groups. Subjects with dental prostheses, regardless of the type, they showed low of motion (border and functional) compared to dentate subjects with no functional alterations whose values have been reported in the literature. The subjects with overdenture have values closer to what is described for young dentate subjects.


RESUMEN: El envejecimiento es un proceso dinámico que incluye varias alteraciones en la cavidad oral, siendo la pérdida de dientes la más frecuente. El tratamiento de rehabilitación puede incluir prótesis fijas o removibles y/o implantes. El objetivo de este estudio fue describir las características geométricas (trayectoria, rangos, áreas) y cinemáticas (velocidad) de los movimientos mandibulares y masticatorios en participantes con prótesis dentales realizando un análisis en tres dimensiones. Se consideró una muestra de 10 participantes con rehabilitación protésica y se dividió en tres grupos (prótesis total, atípica e implantosoportada), se midieron las características de los movimientos mandibulares bordeantes y masticatorios con articulografía electromagnética 3D. Se obtuvo el polígono Posselt en los planos frontal y sagital, se analizaron sus áreas, trayectorias y rangos. Se analizaron los movimientos masticatorios en cuanto al área de cada ciclo, la frecuencia, la velocidad y la razón entre el área el ciclo masticatorio y los movimientos bordeantes, sin diferencias significativas entre los grupos. Los sujetos con prótesis dentales, independientemente del tipo, mostraron disminución de movimiento (bordeante y funcional) en comparación con los sujetos dentados sin alteraciones funcionales cuyos valores se han informado en la literatura. Los sujetos con prótesis implantosoportada tienen valores más cercanos a lo que se describe para sujetos jóvenes dentados.

ABSTRACT

RESUMEN Introducción: La salud bucal en el adulto joven es un derecho humano básico, y su contribución es fundamental para el goce de buena calidad de vida. Objetivo: Determinar la salud bucal en una escuela de formación profesional policial peruana en el período de julio a agosto del 2017. Métodos: Estudio observacional descriptivo de corte transversal. La muestra estuvo conformada por 276 adultos jóvenes seleccionados aleatoriamente, cumpliendo criterios de inclusión y exclusión, según las normas éticas en investigación científica. Se evaluó la salud bucal mediante una ficha epidemiológica con los indicadores: índice CPOD, índice de significancia de caries dental (SIC), índice de higiene oral simplificado (IHO-S) y el índice de necesidad y situación de prótesis dental de la OMS. La evaluación se realizó con luz natural por un observador calibrado. Los datos se analizaron en el programa STATA v 14 mediante tablas de distribución de frecuencias y figuras. Resultados: La prevalencia de caries dental fue de 63,76 por ciento (CPOD= 3,86; SIC= 9,64), IHO-S: 2,02 (DS= 0,41). La prótesis parcial fija fue la que más se usó y se necesitó en ambos maxilares. Conclusiones: La experiencia de caries dental fue moderada, la condición de higiene oral fue regular, y la prótesis parcial fija fue la que más se necesitó y se uso en ambos maxilares. Aunque los indicadores son alentadores, aún urge la necesidad de implementar políticas sanitarias en salud bucal en la comunidad policial(AU)


ABSTRACT Introduction: The oral health of young adults is a basic human right, and its contribution is fundamental for the enjoyment of a good quality of life. Objective: Determine oral health at a Peruvian police academy from July to August 2017. Methods: An observational descriptive cross-sectional study was conducted. The sample was 276 young adults randomly selected according to inclusion and exclusion criteria and in compliance with the ethical standards of scientific research. Oral health was evaluated with the aid of an epidemiological card containing the following indicators: CPOD index, dental caries significance (DCS) index, simplified oral hygiene index (OHI-S), and WHO dental prosthesis need and situation. The evaluation was conducted by a qualified observer under natural light. Data were processed with the software STATA v 14, using frequency distribution tables and figures. Results: Dental caries prevalence was 63.76 percent (CPOD= 3.86; DCS= 9.64), OHI-S: 2.02 (SD= 0.41). Fixed partial dentures were the most commonly used, and they were required in both jaws. Conclusions: Dental caries experience was moderate, oral hygiene status was fair, and fixed partial dentures were the most commonly required for both jaws. Although the indicators are heartening, there is still an urgent need to implement oral health policies in the police community(AU)

ABSTRACT

Hoje em dia no consultório a indicação de uma prótese fixa em cantilever, ainda gera muitas dúvidas, levando o clinico inseguro, muitas vezes a sua contra indicação. Com intuito de esclarecer as características relacionadas à prótese parcial fixa em cantilever realizou- -se uma revisão de literatura. Uma busca foi realizada nas bases de dados Scielo e Pubmed usando-se as palavras-chaves: Prótese fixa, cantilever, dentes suportes. Os artigos dentro do escopo do estudo foram selecionados e pode-se concluir que estas próteses são uma excelente alternativa conservadora para restabelecimento de dentes perdidos, porém para obtenção de resultados satisfatórios com boa longevidade, especial atenção deve ser desprendida aos princípios biomecânicos dos preparos e um controle rigoroso de placa bacteriana deve ser estabelecido.


Actuality the use of Fixed Partial Denture with Cantilever until causes many doubts, making de dentist do not indicate this treatment. To making clear the characteristics relation to this prosthesis, was done a literature review. A search was performed in the Scielo and Pubmed databases using the keywords: Fixed prosthesis, cantilever, supporting teeth. The articles within the scope of the study were selected and it can be concluded that these were an alternative excellent to reestablish the follow teeth, therefore to obtain the good results with respect long-term prosthetic appliances, special attention should be dispensed to the biomechanics principles and optimal hygiene with plaque control should be established.

ABSTRACT

The replacement of missing teeth, especially in the anterior region, is an essential part of dental practice. Fiber-reinforced composite resin bridges are a conservative alternative to conventional fixed dental prostheses or implants. It is a minimally invasive, reversible technique that can be completed in a single visit. The two cases presented herein exemplify the treatment of root-fractured anterior teeth with a natural pontic immediately after extraction.

ABSTRACT

O objetivo deste relato de caso clínico foi descrever a importância de planejar de maneira minuciosa uma alternativa de reabilitação conservadora de um paciente em uso de bisfosfonato intravenoso, bem como detalhar os procedimentos realizados. Paciente do gênero masculino, 78 anos, buscou atendimento odontológico relatando insatisfação com sua condição dentária atual, e o desejo de realizar novas próteses dentárias. Ao exame clínico, observou-se instabilidade da prótese parcial removível superior devido à fratura coronária do elemento 26. Ao exame radiográfico, observaram-se extensas lesões cariosas nos dentes 16 e 26. Após plano de tratamento realizado em equipe multidisciplinar, foi sugerida uma reabilitação sem nenhum procedimento cirúrgico, a fim de minimizar as complicações pós-operatórias e proporcionar saúde oral de maneira mais breve e minimamente invasiva. O tratamento incluiu a confecção de uma prótese parcial fixa dos elementos 13 ao 23 com encaixes de precisão associada à uma prótese parcial removível superior. Já para a arcada inferior, foi realizada uma prótese parcial fixa dos elementos 33 ao 41 e uma prótese parcial removível. Por meio deste caso clinico, foi possível concluir que uma abordagem conservadora possibilitou uma reabilitação que supriu as necessidades estéticas e funcionais do paciente que faz uso de medicamento antirreabsortivo(AU)


The aim of this study was to describe the importance of a carefully planning to conservative rehabilitation alternative for a patient using intravenous bisphosphonate, as well as to detail the procedures performed. A male patient, 78 years old, sought dental care reporting dissatisfaction with his current dental condition and the desire to perform new dental prostheses. At the clinical examination, instability of the superior removable partial denture was observed due to the coronary fracture of element 26. Radiographic examination revealed extensive carious lesions on teeth 16 and 26. After a multidisciplinary treatment planning, was suggested a rehabilitation without any surgical procedure, in order to minimize postoperative complications and provide oral health in a minor and minimally invasive manner. Treatment included a fixed partial denture of elements 13 to 23 with precision fittings attachments associated with a removable partial denture. To the jaw, a fixed partial prosthesis of elements 33 to 41 and a partial removable prosthesis were performed. Through this clinical case, it was possible to conclude that a conservative management provides an aesthetical and functional patient rehabilitation who take antiresorptive medication(AU)

ABSTRACT

Las piezas dentarias vitales que reciben tratamiento en base a prótesis dental fija (PDF) sufren un proceso inflamatorio pulpar durante su preparación, esta respuesta inflamatoria puede ser transitoria o perpetuarse y convertirse en un daño pulpar. Como consecuencia se puede presentar sensibilidad post operatoria en algunos pacientes durante el tratamiento y esta podría estar relacionada con ciertos factores de riesgo. El objetivo del presente trabajo es describir los factores de riesgo relacionados con la sensibilidad postoperatoria termica, quimica o mecanica en el tratamiento mediante prótesis dental fija. Método: Se utilizaron diferentes bases de datos para buscar estudios que incluyeran las siguientes palabras clave: sensibilidad dental, hipersensibilidad dental, respuesta pulpar, corona, prótesis fija, postoperatorio, post cementación, preparación dentaria. Todos los estudios encontrados se analizaron según el nivel de evidencia, la calidad del informe y las implicaciones éticas. Resultados: Se seleccionaron un total de 43 artículos. De ellos, 10 correspondieron a estudios clínicos, 7 revisiones de literatura y 26 estudios in vitro. El nivel de evidencia, la calidad del informe y las consideraciones éticas fueron calificados como regulares. Conclusiones: La evidencia existente describe algunos factores de riesgo relacionados con la sensibilidad postoperatoria en tres etapas del proceso de confección de una prótesis dental fija, pero sin embargo no es concluyente respecto a su mecanismo de origen ni prevención por lo que se sugiere realizar estudios clínicos aleatorizados.

ABSTRACT

PURPOSE: The aim of this study was to compare the flexural strength of provisional fixed dental prostheses which was three-dimensional (3D) printed by several build directions. MATERIALS AND METHODS: A metal jig with two abutment teeth and pontic space in the middle was fabricated. This jig was scanned with a desktop scanner and provisional restoration was designed on dental computer-aided design program. On the preprocessing software, the build angles of the restorations were arranged at 0°, 30°, 45°, 60°, and 90° and support was added and resultant structure was sliced to a thickness of 100 µm. Processed restorations were printed with digital light processing type 3D printer using poly methyl meta acrylate-based resin. After washing and post-curing, compressive loading was applied at a speed of 1 mm/min on a metal jig fixed to a universal testing machine. The maximum pressure at which fracture occurred was measured. For the statistical analysis, build direction was set as the independent variable and fracture strength as the dependent variable. One-way analysis of variance and Tukey's post hoc analysis was conducted to compare fracture strength among groups (α=0.05). RESULT: The mean flexural strength of provisional restoration 3D printed with the build direction of 0° was 1,053±168 N; it was 1,183±188 N at 30°, 1,178±81 N at 45°, 1,166±133 N at 60°, and 949±170 N at 90°. The group with a build direction of 90° showed significantly lower flexural strength than other groups (P<0.05). The flexural strength was significantly higher when the build direction was 30° than when it was 90° (P<0.01). CONCLUSION: Among the build directions 0°, 30°, 45°, 60°, and 90° set for 3D printing of fixed dental prosthesis, an orientation of 30° is recommended as an effective build direction for 3D printing.

ABSTRACT

OBJECTIVE@#This study aimed to compare the passive fits of implant-supported cement-retained computer aided design/computer aided manufacturing (CAD/CAM) bridges fabricated with different implant superstructure designs from zirconia and titanium.@*METHODS@#A total of 32 cubic clods with the same dimensions and with elastic modulus similar to that of mandibles were used. Each clod received two one-stage implants to simulate a partially edentulous jaw that was missing teeth between the lower left second premolar and second molar. Four linear strain gauges were bonded on the region surrounding each implant on the mesial, buccal, distal, and lingual aspects. A total of 32 identical frameworks were fabricated through CAD/CAM after scanning. The frameworks were allocated into four different groups (n=8) in accordance with material types and superstructure designs. Group A included zirconia ceramic implant-supported fixed prostheses with regular marginal designs. Group B comprised zirconia ceramic implant-supported fixed prostheses with full circumferential zirconia-collar marginal designs. Group C consisted of titanium ceramic implant-supported fixed prostheses with regular marginal designs. Group D included titanium ceramic implant-supported fixed prostheses with full circumferential titanium-collar marginal designs. Strain development before and after ceramic veneering was recorded during cement setting. Data were statistically analyzed by using SPSS software.@*RESULTS@#Before ceramic veneering, material types affected the strains of prostheses, and zirconia frameworks showed lower strain than other frameworks (P0.05). Nevertheless, the full circumferential collar marginal design reduced discrepancies among groups (P<0.01).@*CONCLUSIONS@#The passive fits of zirconia prostheses were better than those of titanium-based porcelain-fused-to-metal restorations. The full circumferential collar marginal design can help reduce fit inaccuracy, as well as the adverse effects of ceramic veneering.

ABSTRACT

OBJECTIVE@#This study aims to investigate the fracture resistance and short-term restorative effects of resin-bonded fixed partial dentures (RBFPDs) made from heat-pressed lithium-disilicate-based glass-ceramic (IPS e.max press) and zirconia ceramic (WIELAND) and retained by all-ceramic guiding plates when used to restore missing mandibular second premolars.@*METHODS@#A total of 64 human mandibular first premolars and first molars were prepared as abutments, then were randomly divided into 4 groups (n=8): E0, heat-pressed ceramic RBFPDs, no cyclic loading; E1, heat-pressed ceramic RBFPDs exposed to 300 000 cycles of dynamic loading; W0, zirconia ceramic RBFPDs, no cyclic loading; and W1, zirconia ceramic RBFPDs exposed to 300 000 cycles of dynamic loading. Fracture strength was tested in a universal testing machine.@*RESULTS@#The medians of fracture strength were 1 242.85 N±260.11 N (E0), 1 650.85 N±206.77 N (W0), 1 062.60 N±179.98 N (E1), and 1 167.61 N±265.50 N (W1). Statistical analysis showed that all the groups exhibited significantly higher fracture strength compared with the maximum bite force in the premolar region (360 N; P0.05). Significant statistical differences were found between the zirconia ceramic groups (W0 and W1, P0.05) after dynamic loading.@*CONCLUSIONS@#The RBFPDs retained by all-ceramic guiding plates exhibited promising fracture properties and optimal short-term restorative effects when used to restore missing mandibular second premolars.

ABSTRACT

ABSTRACT OBJECTIVE To conduct a cost-effectiveness analysis of alternatives for rehabilitation treatment of mandibular edentulism in the context of the Brazilian Unified Health System (implant-supported total dental prosthesis versus conventional total dental prosthesis). METHODS A Markov model was developed to capture long-term clinical and economic outcomes. The model's population was comprised of a hypothetical cohort of 1,000,000 patients, aged 55 years, with total mandibular edentulism and without medical contraindications for performing surgical procedures. The adopted analysis perspective was that of the Brazilian Unified Health System. Based on the proposed model, we calculated cost - in BRL, and effectiveness - measured by quality-adjusted prosthesis year (QAPY). The time horizon of the analysis was 20 years. RESULTS Considering a 5% discount in costs and effects, the incremental cost-effectiveness ratio of implant-supported total dental prostheses compared to conventional total dental prosthesis (BRL 464.22/QAPY) was lower than the willingness to pay threshold adopted in the model (BRL 3,050.00/QAPY). CONCLUSIONS The results of this economic analysis showed that the rehabilitation of mandibular edentulous patients by implant-supported total prosthesis is very cost-effective when compared to conventional complete prosthesis, considering the cost-effectiveness limits employed.


RESUMO OBJETIVO Conduzir uma análise de custo-efetividade das alternativas para tratamento reabilitador do edentulismo mandibular no contexto do Sistema Único de Saúde (prótese total implanto-suportada e prótese total convencional). MÉTODOS Foi desenvolvido um modelo de Markov para captar os resultados clínicos e econômicos de longo prazo. A população do modelo consistiu em uma coorte hipotética de 1.000.000 pacientes, com 55 anos, desdentados totais mandibulares e sem contraindicações médicas para a realização de procedimentos cirúrgicos. A perspectiva de análise adotada foi a do Sistema Único de Saúde. Com base no modelo proposto, calculamos o custo (em reais) e a efetividade, medida pelo ano de prótese ajustado à qualidade (QAPY). O horizonte temporal da análise foi de 20 anos. RESULTADOS Considerando o desconto de 5% nos custos e efeitos, a razão de custo-efetividade incremental da prótese total implanto-suportada em relação à prótese total convencional (R$ 464,22/QAPY) foi menor que o limiar de disposição a pagar adotado no modelo (R$ 3.050,00/QAPY). CONCLUSÕES Os resultados desta análise econômica mostraram que a reabilitação de edêntulos mandibulares por meio da prótese total implanto-suportada é muito custo-efetiva em comparação à prótese total convencional, de acordo com os limites de custo-efetividade empregados.

ABSTRACT

PURPOSE: The newest technologies for digital implant impression (DII) taking are developing rapidly and showing acceptable clinical results. However, scientific literature is lacking data from clinical studies about the accuracy of DII. The aim of this study was to compare digital and conventional dental implant impressions (CII) in a clinical environment. MATERIALS AND METHODS: Twenty-four fixed zirconia restorations supported by 2 implants were fabricated using conventional open-tray impression technique with splinted transfers (CII group) and scan with Trios 3 IOS (3Shape) (DII group). After multiple verification procedures, master models were scanned using laboratory scanner D800 (3Shape). 3D models from conventional and digital workflow were imported to reverse engineering software and superimposed with high resolution 3D CAD models of scan bodies. Distance between center points, angulation, rotation, vertical shift, and surface mismatch of the scan bodies were measured and compared between conventional and digital impressions. RESULTS: Statistically significant differences were found for: a) inter-implant distance, b) rotation, c) vertical shift, and d) surface mismatch differences, comparing DII and CII groups for mesial and dist al implant scan bodies (P≤.05). CONCLUSION: Recorded linear differences between digital and conventional impressions were of limited clinical significance with two implant-supported restorations.
