ABSTRACT

Próteses totais imediatas e overdentures mandibulares em carga imediata, são boas alternativas para restaurar a função e a estética. Além disso, proporcionam um fator psicológico positivo, eliminando as consequências emocionais e sociais da perda dos dentes. O objetivo deste estudo foi relatar um caso clínico, com cinco anos de acompanhamento, utilizando parâmetros clínicos e ferramentas qualitativas, para analisar o impacto na qualidade de vida do paciente e no sucesso do tratamento. Este caso clínico foi desenvolvido em um projeto assistencial da Faculdade de Odontologia da Universidade Federal de Minas Gerais, Brasil, que promove a reabilitação oral de pacientes de baixa renda com dentes severamente comprometidos. Paciente do sexo masculino, 57 anos, apresentou-se para tratamento com condição severa de saúde dental e periodontal. O plano de tratamento proposto foi a extração dos dentes remanescentes e confecção de prótese total imediata maxilar e overdenture mandibular, em carga imediata, sobre implantes. O paciente foi acompanhado periodicamente, a cada seis meses, para substituição do o´rings, conforme recomendação do fabricante. Após 5 anos, as próteses foram reembasadas com resina acrílica termopolimerizável e os componentes protéticos da overdenture foram substituídos. Em um acompanhamento qualitativo, a equipe utilizou uma entrevista narrativa, com foco nos impactos do tratamento na qualidade de vida desse paciente. Ele confirmou, em um relato em primeira pessoa, sua satisfação com o tratamento realizado e a melhora nas relações sociais, afetivas e no trabalho, mostrando como a reconquista do sorriso pode transformar a experiência pessoal do indivíduo(AU)


Immediate complete dentures and mandibular immediately loaded overdentures are good alternatives to restore function and aesthetics. Moreover, they provide positive psychological factor, eliminating the emotional and social consequences of tooth loss. The aim of this study was to report a clinical case, with five years of follow-up using clinical parameters and qualitative tools, to analyze the impact on quality of life and the success of treatment. This clinical case was developed in an assistance project of the Dental School of Federal University of Minas Gerais in Brazil, which promotes oral rehabilitation of low-income patients with severely damaged dentitions. A 57-yearold male patient presented for treatment with a severe dental and periodontal health condition. The proposed treatment plan was extraction of the remaining teeth and making maxillary immediate complete denture and mandibular immediately loaded implant-supported overdenture. The patient was monitored periodically, every six months, to replace the polymer ring ball attachment, according to the manufacturer's recommendation. After 5 years, the prostheses were relining with heat-polymerized acrylic resin and overdenture prosthetic components were replaced. In a qualitative follow-up, the team used a narrative interview, focusing on the impacts of treatment in the quality of life of this patient. He confirms, in a firstperson account, his satisfaction with the treatment performed and improvements in social and affective relations and in the work, showing how the reconquest of the smile can transform the personal experience of the individual(AU)

ABSTRACT

Los intermediarios protésicos en implantología oral son los aditamentos que permiten la conexión entre el implante y la prótesis propiamente dicha. Aunque dicha rehabilitación posee una alta tasa de éxito, la selección del pilar protésico representa una fase importante en el tratamiento implantológico. Actualmente, existe una gran variedad de pilares intermediarios, que corresponden a las diversas técnicas y materiales. Los intermediarios protésicos se podrían clasificar según el tipo de conexión, su retención a la prótesis, su relación axial con el cuerpo del implante, su material de fabricación, su tipo de fabricación o si son para rehabilitación unitaria o múltiple. Esta situación puede generarle dudas al rehabilitador al momento de elegir los aditamentos implantológicos idóneos para cada caso en particular, lo que genera un escenario de dilema al seleccionar el aditamento protésico que permita lograr una rehabilitación satisfactoria: funcional, estética y que preserve los principios biológicos. En efecto, la implantología oral ha revolucionado la odontología y seguirá ampliando el abanico de posibilidades; por ello, es importante clasificar las opciones protésicas disponibles. La presente revisión de la literatura tiene como objetivo evidenciar las diferentes alternativas y opciones de pilares intermediarios más utilizados en prótesis sobre implantes. (AU)


Prosthetic intermediaries in oral implantology are attachments that allow connection between the implant and the prosthesis itself. Although this rehabilitation has a high success rate; the selection of the prosthetic abutment represents is important in implant treatment. Currently, there is a great variety of intermediate abutments, corresponding to various techniques and materials. Prosthetic intermediaries can be classified according to the type of connection, their retention to the prosthesis, their axial relationship with the implant body, the manufacturing material and type of manufacture, or whether rehabilitation is single or multiple. This scenario can lead to doubts as to the selection of the ideal implant attachment in each case in order to achieve satisfactory rehabilitation, as well as functional and aesthetic requirements and the preservation of biological principles. Indeed, oral implantology has revolutionized dentistry and will continue to expand the range of possibilities; therefore, it is important to classify the prosthetic options available. The present literature review aims to demonstrate the different alternatives and options available for the intermediate abutments most used in implant prostheses. (AU)

ABSTRACT

Com o avanço da odontologia, os implantes dentários tornaram-se cada vez mais atrativos por oferecerem um melhor conforto, estética e função mastigatória. Todavia, com o aumento da sua utilização também surgiram os problemas, dentre eles a periimplantite. Vista como uma doença irreversível de caráter inflamatório, ela afeta os tecidos ao seu redor, levando à perda. No contexto da Implantodontia, os implantes dentários são afetados pela periimplantite - quando instalada - o que induz à destruição dos tecidos de suporte e proteção adjacentes, ocasionando também a perda destas reabilitações. Portanto, novas reabilitações devem ser planejadas para que possam corrigir os defeitos causados pela doença. Dentre as opções, a técnica "All on four" apresenta-se como vantajosa, po dendo ser escolhida para grandes reabilitações. Logo, o presente artigo tem o objetivo de descrever um caso clínico utilizando a técnica "all on four" que reabilitou um paciente edêntulo em mandíbula, na qual possuía implantes afetados pela periimplantite, optando-se pela remoção e nova instalação de 4 implantes pela técnica escolhida. Após 4 meses, foi realizada a instalação da prótese definitiva... (AU)


With the advancement of dentistry, dental implants have become increasingly attractive as they offer bet ter comfort, aesthetics and masticatory function. However, with the increase in its use, problems also arose, among them the peri-implantitis disease. Seen as an irreversible disease with an inflammatory character, it affects the tissues around it, leading to loss. In the context of Implantology, dental implants are affected by peri-implantitis - when installed - which induces the destruction of adjacent support and protective tissues, also causing the loss of these rehabilitations. Therefore, new rehabilitation must be planned so that they can correct the defects caused by the disease. Among the options, the "All on four" technique presents itself as an advantage and can be chosen for major rehabilitation. Therefore, the present article aims to describe a clinical case using the "all on four" technique that rehabilitated an edentulous patient in the mandible, in which he had implants affected by peri-implantitis, opting for the removal and new installation of 4 implants by the technique chosen. After 4 months, the definitive prosthesis was installed... (AU)

ABSTRACT

Este estudo objetivou analisar a terapêutica medicamentosa em implantodontia e propor um protocolo clínico baseado em evidências. Os implantes dentários revolucionaram o tratamento reabilitador em Odontologia com elevadas taxas de sucesso na sua realização. Por se tratarem de procedimentos de natureza invasiva e graças as características dos pacientes que se submetem a este tratamento, seu operador deverá considerar alguns aspectos que serão imprescindíveis para o sucesso do procedimento, aspectos que vão desde o condicionamento emocional do paciente no pré-operatório, os cuidados na escolha da solução anestésica a ser empregada, a efetividade no controle da dor e do edema inflamatório bem como a prevenção de algumas complicações como a infecção dos tecidos perimplantares. Protocolos farmacológicos atrelados a prática implantodôntica são escassos na literatura atual e diante disto foi sugerida a inserção de uma proposta de esquema terapêutico farmacológico que poderá ser utilizado como protocolo nas mais variadas situações enfrentadas pelo operador durante as cirurgias em implantodontia... (AU)


This study aimed to analyze drug therapy in implantology and to propose an evidence-based clinical protocol. Dental implants have revolutionized dental rehabilitation treatment with high success rates. Because they are invasive procedures and due to the characteristics of patients undergoing this treatment, your operator should consider some aspects that will be essential for the success of the procedure, aspects ranging from the emotional conditioning of the patient preoperatively, care in choosing the anesthetic solution to be employed, effectiveness in controlling pain and inflammatory edema, as well as the prevention of some complications such as infection of the perimplant tissues. Pharmacological protocols linked to implantodontic practice are scarce in the current literature and, therefore, it was suggested to insert a proposal for a pharmacological therapeutic scheme that can be used as a protocol in the most varied situations faced by the operator during implant surgery...

ABSTRACT

A Mucosite peri-implantar é considerada a precursora da peri-implantite, ela é uma lesão inflamatória da mucosa peri-implantar na ausência de perda óssea marginal contínua. O objetivo desse relato de caso, foi descrever o tratamento da mucosite periimplantar através da cirurgia de enxerto gengival livre. Foi proposto, portanto, um tratamento reabilitador envolvendo uma abordagem multidisciplinar de forma a resgatar e restabelecer estética, função e bem-estar através do enxerto gengival livre para melhorar as características de mucosa e viabilizar uma previsibilidade de uma prótese definitiva implantosuportada em condições teciduais mais estáveis. O uso do EGL para aumento da gengiva queratinizada na cirurgia de implantes em paciente idosos é uma solução prática e segura para a manutenção da saúde periodontal ao redor do implante... (AU)


Peri-implant mucositis is considered the precursor of peri-implantitis, it is an inflammatory lesion of the peri-implant mucosa in the absence of continuous marginal bone loss. The purpose of this case report was to describe the treatment of peri-implant mucositis through free gingival graft surgery. Therefore, a rehabilitation treatment involving a multidisciplinary approach was proposed in order to rescue and reestablish aesthetics, function and well-being through the free gingival graft to improve the characteristics of the mucosa and enable a predictability of a permanent implant prosthesis under more stable tissue conditions. The use of EGL to increase keratinized gingiva in implant surgery in elderly patients is a practical and safe solution for maintaining periodontal health around the implant... (AU)

ABSTRACT

A estabilidade primária dos implantes é uma etapa muito importante que pode tornar-se determinante no sucesso das reabilitações protéticas. A integração entre tecido ósseo e implantes leva um tempo determinado para ocorrer. Algumas formas de terapêutica podem ser usadas com o intuito de diminuir e acelerar esse tempo de osseointegração. Em nosso estudo foram selecionados 20 pacientes que necessitavam de exodontias em molares inferiores bilaterais. As exodontias foram realizadas nomesmomomento cirúrgico, onde um lado foi o controle e o outro recebeu a Terapia da Fotobiomodulação (PBMT) nos momentos: imediatamente pós-cirurgia, após 24, 48, 72, 96 horas, e 7 e 15 dias (a aplicação da PBMT seguiu o protocolo de cegamento). Após 45 dias das exodontias foram instalados os implantes e a estabilidade primária destes foi avaliada pela Análise de Frequência de Ressonância (RFA) por meio de Osstell® (na escala ISQ). Após 90 dias da instalação dos implantes, no momento da reabertura, foi realizada novamente a mensuração da estabilidade com Osstell® ISQ. Com os valores obtidos foram realizados os testes estatísticos de média, desvio padrão, teste t pareado do lado controle e do lado onde foi aplicado a PBMT, nos dois tempos (momento da instalação dos implantes e após 90 dias) de todos os pacientes da pesquisa. Concluímos que a utilização do Osstell® ISQ após a aplicação da PBMT, não apresentou efeitos estatisticamente significativos quando avaliamos o ISQ em diferentes momentos (P=0,488; P=0,520; P=0,356; P=0,621).

ABSTRACT

Introducción: La instalación inmediata del implante posterior a la extracción dental se está convirtiendo en un procedimiento de rutina debido a la reducción del tiempo de tratamiento y a la preservación de las estructuras anatómicas remanentes. Sin embargo, en muchos casos esta técnica involucra dientes afectados con procesos infecciosos. Hasta ahora, no se ha descrito a ciencia cierta el grado de éxito o fracaso del implante inmediato en alvéolos infectados, ni se ha establecido un protocolo para el manejo de este tipo de casos. Objetivo: Realizar una revisión bibliográfica actualizada, para determinar qué consideraciones se deben tener para instalar un implante inmediato en alvéolos con procesos infecciosos. Conclusión: Es posible obtener las ventajas de la instalación inmediata del implante en alvéolos infectados mediante la aplicación de un adecuado manejo clínico, donde se considere un adecuado tratamiento antibiótico, acompañado de un correcto curetaje alveolar, respetar la cadena de asepsia y antisepsia, posición subcrestal del implante y obtener siempre una buena estabilidad primaria del implante (AU)


Introduction: The immediate placement of the implant after dental extraction is a procedure that every time is becoming a routine procedure due to the reduction of the treatment time and the preservation of the remaining anatomical structures. However, in many cases, this technique involves affected teeth with infectious processes. Until now, the degree of success or failure of the immediate implant in infected alveoli has not been described for sure; nor has a protocol been established for the management of these types of cases. Objective: Carry out an updated bibliographic review, to determine what considerations must be taken to install an immediate implant in alveoli with infectious processes. Conclusion: Is possible obtain the advantages of the immediate installation of the implant in infected alveoli through the application of adequate clinical management, where appropriate antibiotic treatment is considered, accompanied by proper alveolar curettage, respect the aseptic and antiseptic chain, implant subcrestal position and always obtain a good primary stability of the implant (AU)

ABSTRACT

La estabilidad primaria es un requisito importante para la supervivencia y éxito de los implantes durante la osteointegración. En los últimos años, los implantes inmediatos postextracción han demostrado ser una opción de tratamiento exitosa y predecible para la reposición de dientes con mal pronóstico, pero surge la duda de si dichos implantes alcanzan valores de estabilidad primaria comparables a aquellos colocados en hueso maduro. Comparar la estabilidad primaria de implantes inmediatos colocados en alveolos postextracción con la de implantes colocados en hueso maduro. Se llevó a cabo un estudio clínico retrospectivo, con los datos recogidos sobre 175 implantes, colocados en 175 pacientes. Todos los implantes colocados pertenecían al modelo Essential Cone (Klockner Implant System) y se dividieron en dos grupos: implantes inmediatos (Grupo A, n=31) e implantes colocados en hueso maduro (Grupo B, n=144). La estabilidad primaria de todos los implantes se midió mediante torque de inserción y análisis de frecuencia de resonancia con Osstell ISQ. No se encontraron diferencias estadísticamente significativas respecto a la estabilidad medida a través del torque de inserción (26,29+10,07 Vs 25,76+9,72 N/cm) pero sí que se encontraron diferencias significativas en la medida de la estabilidad primaria mediante AFR, siendo inferiores los valores correspondientes a los implantes colocados en los alveolos post exodoncia (60,74 ± 6,17 en sentido VL y 62,19 ± 7.64 en sentido MD frente a 68,34 ± 6.26 en sentido VL y 69,29 ± 7.98 en sentido MD obtenidos en los implantes colocados en hueso maduro). El torque de inserción de los implantes inmediatos es similar al de los implantes colocados en hueso maduro, pero sus valores ISQ son significativamente inferiores, lo que demuestra un mayor grado de micromovimiento, y por consiguiente, un mayor riesgo de fracaso durante el período de osteointegración.


Primary stability is an important requirement for the survival and success of implants during osseointegration. In recent years, immediate post-extraction implants have proven to be a successful and predictable treatment option for the replacement of teeth with a poor prognosis, but the question arises as to whether these implants reach primary stability values comparable to those placed in mature bone. The objective of the study was to compare the primary stability of immediate implants placed in post-extraction alveoli with that of implants placed in mature bone. A retrospective clinical study was carried out, with data collected on 175 implants, placed in 175 patients. All implants placed belonged to the Essential Cone model (Klockner Implant System) and were divided into two groups: immediate implants (Group A, n = 31) and implants placed in mature bone (Group B, n = 144). The primary stability of all implants was measured by insertion torque and resonance frequency analysis with Osstell ISQ. No statistically significant differences were found regarding the stability measured through the insertion torque (26.29 + 10.07 Vs 25.76 + 9.72 N / cm) but significant differences were found in the measurement of primary stability by means of AFR, the values corresponding to implants placed in the post-exodontic alveoli being lower (60.74 ± 6.17 in the VL direction and 62.19 ± 7.64 in the MD direction versus 68.34 ± 6.26 in the VL direction and 69.29 ± 7.98 in the MD direction obtained in implants placed in mature bone). The insertion torque of immediate implants is similar to that of implants placed in mature bone, but their ISQ values are significantly lower, which demonstrates a higher degree of micromotion, and therefore, a greater risk of failure during the period of osseointegration.

ABSTRACT

RESUMEN: Algunas técnicas como la regeneración ósea guiada, uso de rellenos óseos y membranas se han planteado para limitar la reabsorción ósea post exodoncia. La técnica de "socket-shield" preserva un fragmento de raíz vestibular como medio para preservar la cortical ósea bucal. El presente reporte describe un caso clínico de fractura coronaria en un incisivo central superior que fue segmentado parcialmente y la porción vestibular de la raíz fue preservada para mantener la arquitectura de la cortical vestibular, al mismo tiempo se colocó un implante dental. Posterior a la rehabilitación fija, y con un seguimiento de un año se evidenció la preservación de los tejidos blandos periimplantarios a nivel de la mucosa y tejido óseo. No se observó alteraciones en la oseointegración y la pérdida ósea marginal periimplantaria fue nula. Se concluye que la técnica de "socket-shield" parece conservar clínicamente la arquitectura de la mucosa y el tejido óseo sin ocasionar patologías periimplantarias.


ABSTRACT: Some techniques such as guided bone regeneration with the use of bone fillings and membranes have been proposed to limit bone resorption. The socket-shield technique preserves a fragment of the vestibular root as a means of preserving the buccal bone cortex. This report describes a clinical case of coronary fracture in an upper central incisor that was partially segmented and the vestibular portion of the root was preserved to maintain the architecture of the vestibular cortex; at the same time, a dental implant with immediate provisionalization was placed. After the fixed rehabilitation and with a follow-up of one year, the preservation of the soft peri-implant tissues at the level of the mucosa and bone tissue was evidenced. No alterations in osseointegration were observed and marginal peri-implant bone loss was null. It is concluded that the socket-shield technique seems to clinically conserve the architecture of the mucosa and bone tissue without causing peri-implant diseases.

ABSTRACT

RESUMEN: El objetivo de este artículo es evaluar el éxito clínico de una nueva alternativa para crear papilas en implantes de carga inmediata, que se realizó en una paciente de sexo femenino de 26 años de edad. Se inició el tratamiento con la confección de una guía quirúrgica, previo a la manipulación de los tejidos para crear las papilas peri-implantarias. En la cirugía se realizan 2 incisiones semilunares, unidas por una incisión perpendicular, las que al suturarlas sobre ellas mismas permitió crear las papilas; se instala un implante con buena estabilidad primaria y se toma la impresión para la rehabilitación. A las 24 horas se instala una corona atornillada, mostrando la presencia de las papilas de forma inmediata. Se realiza controles hasta los 20 meses de función, evidenciando buena estabilidad de las papilas mesial y distal sin presentar ningún tipo de complicación.


ABSTRACT: The aim of this paper is to evaluate the clinical success of a new alternative to create papillae in immediate load implants, which was performed in a 26-yearold female patient. The treatment was started with the preparation of a surgical guide, prior to the manipulation of tissues to create the peri-implant papillae. In the surgery, two semilunar incisions are made, joined by a perpendicular incision, which when sutured on them allowed to create the papillae. An implant with good primary stability is installed and the impression is taken for rehabilitation. At 24 h a screwed crown is installed, showing the presence of the papillae immediately. Controls are performed up to 20 months of function, demonstrating good stability of the mesial and distal papillae without presenting any type of complication.

ABSTRACT

Los implantes dentales se han colocado en sitios de extracción cicatrizados mediante un procedimiento quirúrgico en dos etapas para un periodo de tres a seis meses sin carga. Sin embargo, los pacientes esperan ser rehabilitados lo antes posible, especialmente los pacientes sometidos a restauraciones estéticas en el maxilar anterior. Después de la colocación del implante, la fabricación de la restauración temporal y la carga del implante dentro de las 48 horas se denominan carga inmediata. Esto acorta el tiempo del tratamiento, ya que requiere menos intervenciones quirúrgicas, reduce la pérdida ósea crestal periimplantaria, conduce a la preservación de la morfología de los tejidos blandos y mejora la estética. En este artículo se hablará del caso clínico de un paciente femenino de 44 años de edad que presentaba pérdida del órgano dentario 21. Se realizó valoración periodontal, radiográfica y tomográfica de este órgano dentario, se colocó implante con la utilización de guía quirúrgica y protésica acrílica termocurable, se realizó carga inmediata, el provisional fue conformado con contorno subgingival cóncavo y se toman en cuenta criterios de contorno crítico y subcrítico para el desarrollo ideal del perfil de emergencia. En las citas de valoración se encontraron los tejidos periimplantales estables y la paciente no refirió sintomatología (AU)


Dental implants have been placed in scarred extraction sites by a twostage surgical procedure for a period of three to six months without load. However, patients expect to be rehabilitated as soon as possible, especially patients undergoing esthetic restorations in the anterior maxilla. After implant placement, the fabrication of the temporary restoration and implant loading within 48 hours are called immediate loading. This shortens the time of treatment, beacause it requires fewer surgical interventions, reduces peri-implant crestal bone loss, leads to the preservation of soft tissue morphology and improves aesthetics. In this article we will discuss the clinical case of a 44-year-old female patient who had lost the dental organ 21. Periodontal, radiographic and tomographic assessment of this dental organ was performed, an implant was placed with the use of surgical guide and acrylic prosthesis thermocurable, immediate loading was performed, the provisional was formed with a concave subgingival contour and critical and subcritical contour criteria were taken into account for the ideal development of the emergence profile. In the assessment appointments stable periimplant tissues were found and the patient did not report symptoms (AU)

ABSTRACT

Introducción: Dentro del marco de su actividad profesional el estomatólogo se enfrenta a diversas afecciones como la reabsorción radicular interna, cuyos casos avanzados pueden complicar el pronóstico del tratamiento endodóntico, debido al debilitamiento de la estructura dental remanente y las posibles afectaciones periodontales. Debido a que la boca está localizada en uno de los puntos focales de la cara, cualquier alteración en la apariencia estética puede provocar implicaciones psicológicas que pueden ir desde una simple forma de esconder el defecto hasta la más grande introversión. Objetivo: Presentar un caso clínico de reabsorción dentaria interna resuelto con implante postextractivo de carga inmediata. Presentación de caso: Paciente femenina de 31 años con reabsorción dental interna de incisivo central superior. Se llevó a cabo un adecuado diagnóstico y plan de tratamiento del caso, colocándose un implante transalveolar cargado de forma inmediata y la rehabilitación definitiva metalcerámica una vez concluida la fase de osteointegración. Conclusiones: Se consiguió una rehabilitación estética, funcional y biomecánicamente estable a largo plazo, que coincide con las expectativas del paciente, lo cual demuestra que cuando se cumplan los requisitos adecuados y la planificación sea exhaustiva, la implantología ofrece el tratamiento más avanzado en casos en que es inminente la extracción dental(AU)


Introduction: In their daily professional practice dentists are faced with a variety of conditions. An example is internal root resorption, the advanced stage of which may complicate the prognosis of dental treatment, due to the weakening of the remnant dental structure and the potential appearance of periodontal disease. Because the mouth is located in one of the focal points of the face, any alteration of its esthetic appearance may result in psychological disorders ranging from a simple attempt to mask the defect to the greatest introversion. Objective: Present a clinical case of internal tooth resorption solved with a post-extraction immediate load implant. Case presentation: A female 31-year-old patient presents with internal tooth resorption of the maxillary central incisor. Appropriate diagnosis was performed and a treatment plan devised, consisting in immediate placement of a transalveolar implant and definitive metal-ceramic rehabilitation upon completion of the osseointegration stage. Conclusions: Stable long-term esthetic, functional and biomechanical rehabilitation was achieved which met the patient's expectations. This result shows that when the established requirements are complied with and exhaustive planning is performed, implantology offers the most advanced treatment when dental extraction is imminent(AU)

ABSTRACT

OBJECTIVE@#To compare the clinical effects of a modified socket shield technique (SST) and the conventional immediate implant placement in the esthetic zone.@*METHODS@#Twenty-four patients with one hopeless upper incisor were consecutively enrolled in this study. All patients were scheduled for immediate implant placement. Twelve patients underwent a modified SST (experimental group) whereas the others underwent conventional procedures (control group). Radiographic and clinical data were obtained preoperatively, immediately after surgery, and 12 months after surgery. The success rate of the implants, the pink esthetic score (PES) and patient satisfaction were analyzed. Statistical analysis was conducted using SPSS 21.0 software.@*RESULTS@#One year after operation, the success rate of the implants was 100% in both groups. The PES and patient satisfaction of the experimental group were significantly higher than those of the control group (P<0.05). The buccal bone plate resorbed less in the experimental group than in the control group (P<0.05).@*CONCLUSIONS@#The modified SST is advantageous over the conventional immediate implant placement in terms of buccal bone and soft tissue maintenance.

ABSTRACT

OBJECTIVE@#To explore the feasibility of immediate implantation after tooth extraction in the maxillary molar socket with poor bone quality beneath the sinus.@*METHODS@#We collected the data from the patients undergoing extraction of maxillary molars with poor bone quality between the sockets and sinuses. Sinus lifting and immediate implant following the extraction were performed simultaneously in these cases, and the primary stability of the implants, wound healing, and changes of the sinus were observed. At 6 months after the operations, the crowns were installed on the implants. The masticatory function was observed, and the growth of the alveolar bones and their changes after the operations were examined using microcomputed tomography (MCT).@*RESULTS@#We analyzed 32 extraction cases with immediate implantation in the maxillary molar sockets with poor bone quality beneath the sinus. The average age of the patients was 59.8 years, and the length and diameter of the implant ranged from 8.5 to 10 mm and from 4.5 to 5.5 mm, respectively. The torque force of the implants varied from the minimum (in which cases the implants remained fixed after insertion with fingers) to the maximum of 30 N·cm. The postoperative recovery was uneventful in all the cases and no failed or movable implants were found. At 6 months after the operation, none of the patients showed abnormalities in the sinus, and in all the cases the crowns were successfully installed on the implants with good recovery of the masticatory functions. Follow-up of the patients for 12 to 96 months after the operation showed successful immediate implantation in all the cases. After the operation, the changes of the mean alveolar ridge heights on the buccal, palatal, mesial, and distal sides of the patients were 0.8069±0.6253 mm (=1.2904, >0.1), 0.5272± 0.3331 mm (=1.5836, >0.05), 0.5416±0.4048 mm (=1.3379, >0.05), and 0.5172±0.3874 mm (=1.3351, >0.05), respectively; the change of the alveolar ridge width was 0.5522±0.4381 mm (=1.2604, >0.1) mm. The dimension of the alveolar bone underwent no significant changes after the operation in these patients.@*CONCLUSIONS@#Immediate implantation in the maxillary extraction socket with a poor bone quality can avoid damages to the sinus and achieve good outcomes with such advantages of less trauma, full use of the innate gingiva and alveolar ridge, and well preserved morphology of the alveolar ridge as compared with delayed implantation.

ABSTRACT

OBJECTIVE@#This study aimed to evaluate the clinical effect of the socket-shield technique in the maxillary anterior region at one year after implant placement.@*METHODS@#Ten patients with maxillary anterior teeth that cannot be reserved were enrolled. Implants were installed following the socket-shield technique and restored six months after the surgery. The thickness of the labial maxillary bone of the implant was compared before and one year after the surgery. At one year follow-up, the reten-tion rate of the implants, Jemt classification, and pink and white aesthetic scores were evaluated. Postoperative complications and patient satisfaction were also analyzed.@*RESULTS@#One year after installation, the retention rate of the implant was 100%. The thickness of the maxillary bone at the neck, central, and root section of the implant reduced to (0.27±0.21), (0.19±0.20), and (0.28±0.29) mm, respectively, compared with the values immediately after the operation. The thickness of the labial maxillary bone at the three measurement points immediately after and one year after the operation was statistically significant (P0.05) of the difference thickness between immediate and one year after operation at the three measurement points. The pink esthetic scores of the implant prosthesis was 9.10±0.54, and the white esthetic scores was 9.00±0.63. No complications were observed, and the patients had a high degree of satisfaction.@*CONCLUSIONS@#The socket-shield technique could provide acceptable treatment results but cannot completely avoid the reconstruction of the labial maxillary bone of the implants. The technique exhibits favo-rable short-term aesthetic result, but its long-term clinical effect and aesthetic problems need to be further studied.

ABSTRACT

Abstract The immediate loading of implant-assisted fixed prostheses in edentulous maxillae may achieve favorable success rates with reduced treatment time. An evidence summary of clinical trials is key to recommend loading protocols in these cases. Objectives To compare immediately loaded, fully implant-supported complete dentures to early and conventional/delayed loading in the edentulous maxillae of adult patients by a systematic review of controlled clinical trials (CCT). Methodology CCTs reports were identified up to January 17, 2019 from Cochrane Oral Health Group's Trial register, Cochrane Central Register of controlled trials (CENTRAL), MEDLINE (Ovid), BIOSIS, EMBASE, CINAHL, Web of Science, and DARE. Two independent reviewers screened titles/abstracts and confirmed inclusion using full texts. Data were extracted and quality assessed (Cochrane Risk of Bias tool) independently and in duplicate. Study heterogeneity prevented pooling by meta-analysis. Results Out of 1,052 candidate studies, four CCTs were included. Two trials had patient satisfaction as an outcome: (1) A randomized trial compared immediately and early loaded fixed dentures and found more satisfaction with the first after 12 months; (2) A non-randomized study found better satisfaction with immediate fixed dentures compared to conventional loading after 3 months (no more at 12 months). Regarding implant success and prosthetic complications, three trials did not report significant differences comparing immediate loading to other protocols. Conclusions This review found weak evidence of differences between immediate load and other loading regimens, regarding patient satisfaction and maintenance events/adversities. The potential of immediate loading for favorable results in edentulous maxillae reinforces the need for well-designed RCTs, for solid clinical guidelines. Registration number CRD42018071316 (PROSPERO database).

ABSTRACT

Abstract Introduction For complete rehabilitation of fully edentulous mandibles, the option for immediate loading determines the use of temporary prostheses that splint the installed implants. Although temporary prostheses with reinforcement provide rehabilitations with biomechanical benefits, the non-adoption of this recommendation coexists in different studies on immediate restorations. Objective This study evaluates a type of prosthesis to restore jaws by the all-on-four concept. Material and method: The mechanical behavior of prostheses with the modified framework was evaluated in vitro, under a cantilever mechanical unilateral bending test. Two representative groups were included in the all-on-four concept, with a G1 test group (n = 10) containing modified frameworks and a G2 control group (n = 10) that included full acrylic prostheses. The samples were submitted to thermal cycling with 500 cycles (5° ± 2 °C for 30 s, and 55° ± 2° for 30 s) and to the mechanical bending test on the cantilever. Result The Mann-Whitney test revealed a significant difference between G1 and G2 (p <0.001). In the descriptive evaluation, G1 averaged 830.50 N until the initial resin fracture, while the control group presented a mean of 403.58N. The maximum resistance until complete fracture was recorded in G1, with a mean of 903.03N, while in G2, a mean of 435.20N was recorded. The linear vertical component of the flexion was 0.68 mm and 0.39 mm until the initial fracture of the bar, respectively for G1 and G2. Conclusion The modified framework for the all-on-four protocol determined better mechanical performance when compared to the same full acrylic prosthesis model.


Resumo Introdução Para reabilitação de mandíbulas totalmente edêntulas, a opção por carga imediata determina a utilização de próteses provisórias que esplintem os implantes instalados. Apesar de provisórias com reforço proverem as reabilitações com benefícios biomecânicos, a não adoção desta indicação coexiste em diferentes estudos sobre restaurações imediatas. Objetivo Este estudo avaliou um tipo de prótese para reabilitar mandíbulas pelo conceito "all-on-four". Material e método: Foi avaliado, in-vitro, o comportamento mecânico de próteses com a infraestrutura modificada, sob ensaio mecânico de flexão unilateral em cantilever. Foram avaliados dois grupos representativos para o conceito "all-on-four", sendo um grupo teste G1 (n = 10) contendo próteses com infraestrutura modificada e outro controle G2 (n = 10) que incluiu próteses totalmente acrílicas. As amostras foram submetidas à ciclagem térmica com 500 ciclos (5° ± 2 °C por 30 segundos e 55° ± 2 °C pelo mesmo tempo) e submetidas ao ensaio mecânico à flexão sobre o cantilever. Resultado O teste de Mann-Whitney revelou diferença significativa entre G1 e G2 (p<0,001). Na avaliação descritiva, G1 mostrou média de 830,50 N até a fratura inicial em resina e o grupo controle apresentou média de 403,58N. A resistência máxima até a fratura completa foi de 903,03 N para G1 e para G2 de 435,20 N. O componente vertical linear de flexão foi 0,68 mm e 0,39 mm até a fratura inicial da barra, respectivamente para G1 e G2. Conclusão A infraestrutura modificada para o protocolo "all-on-four" proporcionou melhor desempenho mecânico quando comparado ao mesmo modelo de prótese totalmente acrílico.

ABSTRACT

ABSTRACT Introduction Dental implant therapy, when well planned, can contribute to the patient's quality of life and is an important tool for solving a serious public health problem in various parts of the world. Objective This study investigated peri-implant health in fixed implants supported by an immediate loading technique and to associate those outcomes with sociodemographic conditions. Material and method After the disassembly of the prostheses on implants with the "Branemark Model" the peri-implant health of 93 patients was evaluated using dental plaque index (DPI), probing pocket depths (PPD), bleeding on probing (BOP), clinical attachment levels (CAL), and presence of gingival hyperplasia. Patients also answered a questionnaire about their gender, age, socioeconomic status (Brazilian Association of Research Companies - ABEP), general health and tobacco use. Result The most constant clinical findings were the presence of plaque, followed by gingival hyperplasia and periimplantitis, which was associated with disease progression. Most of the patients in the study were female, Caucasian, and under 60 years of age, with prostheses located in their lower arch, and they belonged to social classes A and B. Conclusion The presence of dental biofilm occurred in almost all implants and was not related to the presence of periimplantitis. The progression of periimplantitis with bone loss was related to sub gingival bleeding. The sociodemographic characteristics in the study did not present great correlations with the clinical variables of the dental implants studied.


RESUMO Introdução A terapia de implantes dentais, quando bem planejada, pode contribuir para a qualidade de vida do paciente e é uma ferramenta importante para solucionar um sério problema de saúde pública em várias partes do mundo. Objetivo Este estudo investigou a saúde peri-implantar em implantes fixos apoiados por uma técnica de carga imediata e associou esses resultados a condições sociodemográficas. Material e método Após a desmontagem das próteses sobre implantes com o "Modelo de Branemark", a avaliação peri-implantar de 93 pacientes foi avaliada por meio do índice de placa dental (IPD), profundidade de sondagem (PS), sangramento à sondagem (SS), níveis clínicos de fixação (NCF) e presença de hiperplasia gengival. Os pacientes também responderam a um questionário sobre sexo, idade, nível socioeconômico (Associação Brasileira de Empresas de Pesquisa - ABEP), saúde geral e tabagismo. Resultado Os achados clínicos mais constantes foram a presença de placa, seguida de hiperplasia gengival e periimplantite, que esteve associada à progressão da doença. A maioria dos pacientes do estudo era do sexo feminino, caucasiana e com idade inferior a 60 anos, com próteses localizadas na arcada inferior, pertencentes às classes sociais A e B. Conclusão A presença de biofilme dentário ocorreu em quase todos os implantes e não foi relacionado à presença de periimplantite. A progressão da peri-implantite com perda óssea foi relacionada ao sangramento subgengival. As características sociodemográficas do estudo não apresentaram grandes correlações com as variáveis clínicas dos implantes dentários estudados.
