Introdução:
As próteses sobre implantes são uma das opções disponíveis para reabilitar espaços desdentados. São vários os componentes e as etapas no seu fabrico que podem afetar o sucesso do tratamento. Deste modo, a caracterização e a recolha de dados relativo a possíveis complicações pode ajudar na otimização dos tratamentos com próteses sobre implantes. Este estudo pretende contribuir para um melhor conhecimento da realidade das próteses sobre implantes fabricadas por Técnicos de Prótese Dentária em Portugal.
Materiais e Métodos:
A recolha de dados foi efetuada através de um questionário aplicado a Técnicos de Prótese Dentária. O questionário foi desenvolvido na plataforma digital Qualtrics® e partilhado de 3 formas: e-mail direto a Laboratórios de Prótese; e-mail à Associação Portuguesa de Técnicos de Prótese Dentária e pedido de resposta com hiperligação para o questionário em fóruns de Técnicos de Prótese Dentária. Foram enviados lembretes todas as semanas durante um mês.
Resultados:
De um total de 155 questionários, 60 foram considerados como amostra válida. 95 foram excluídos por estarem incorretamente preenchidos. A maioria dos Técnicos de Prótese, 68,3%, realizam tanto Prótese Fixa sobre Implantes como Prótese Removível sobre Implantes. Apenas 6,7% executa exclusivamente Prótese Removível sobre Implantes.
A maioria da prótese fixa sobre implantes é cimento-aparafusada (53,6%). No sector anterior, o material mais utilizado é a zircónia com recobrimento vestibular, enquanto na secção posterior é a zircónia monolítica “pintada”. Os pedidos de reparação mais comuns ocorreram devido a chipping da restauração.
Relativamente às próteses removíveis sobre implantes, o retentor mais usado é do tipo “locator®” e os pedidos de reparação mais comuns ocorreram devido à fratura de dentes ou da base da prótese e ainda a perda de dentes.
Conclusão:
Dentro das limitações deste estudo, podemos concluir que o chipping é ainda uma complicação importante da reabilitação protética com implantes dentários, o que deverá alertar os Técnicos de Prótese Dentária e os Médicos Dentistas de forma a otimizarem a escolha do material, a confeção da infra-estrutura, o desenho da prótese e a oclusão da mesma. As fraturas que podem ocorrer na prótese removível sobre implantes devem também alertar os profissionais para um correto desenho protético e para a verificação do assentamento perfeito da prótese na respetiva área de suporte.
Introduction: Implant-supported prostheses are one of the options available to rehabilitate an edentulous space. This type of dental prosthesis involves several components and steps in their production that may affect the success of the rehabilitation. The characterization of this prosthesis and the record of its possible complications may be helpful in the optimization of this type of rehabilitations. The aim of this study is to characterize implant-supported prostheses produced by Portuguese Dental Technicians. Material and Methods: The data was collected using a questionnaire applied to Dental Technicians. The survey was developed in the online platform Qualtrics® and shared by 3 ways: e-mail to Dental Prostheses Laboratories; e-mail to Portuguese Association of Dental Technicians (APTPD), and request with the survey link in Portuguese online forums of Dental Technicians. Reminders were sent every week, during a month. Results: A total of 155 surveys were answered. However, only 60 were considered for the valid sample. 95 were excluded because they were incomplete. The majority of the Dental Technicians, 68,3%, performed both fixed and removable implant-supported prostheses. Only 6,7% performed exclusively removable implant-supported prostheses. The majority of the fixed implant-supported prostheses is cement-screw (53,6%) or only screw-retained (44,6%). In the anterior sector, the material most used is zirconia with vestibular veneering. In the posterior section, stained monolithic zirconia. The most frequent repair demand is due to restauration chipping. Concerning removable implant-supported prostheses, the most used attachment is “locator®” type and the most frequent repair is the fracture of tooth or denture base, and tooth loss. Conclusion: Within the limitations of this research, we can conclude that restauration chipping is still one important complication in prosthetic rehabilitations with dental implants. This should alert Dental Technicians and Dentists to improve material selection, framework design and occlusion. The fractures that may occur on removable implant-supported prostheses should also alert the professionals for a better prosthetic design and the correct fit of the prostheses in their support area.
