Introdução: Em pacientes desdentados a reabilitação oral pode ser realizada através de prótese sobre implantes. São várias as etapas clínicas e laboratoriais que compreendem este processo, detendo cada uma destas um papel específico no sucesso do tratamento. Nesta investigação pretendemos analisar as principais opções, complicações/limitações neste tipo de prótese, do ponto de vista dos Técnicos de Prótese Dentária. Materiais e Métodos: Os dados desta investigação foram recolhidos através de um questionário aplicado a Técnicos de Prótese Dentária em Portugal, desenvolvido na plataforma Qualtrics® e distribuído de 2 formas: contato via e-mail com laboratórios e respetivos Técnicos de Prótese Dentária, e solicitação de divulgação pela Associação Portuguesa de Técnicos de Prótese Dentária. Resultados: Foram obtidos 190 questionários considerados válidos. Verificou-se que 64% dos Técnicos de Prótese Dentária realizam tanto prótese fixa como removível sobre implantes, 25,3% só prótese fixa e 10,7% só prótese removível. Dos resultados obtidos, destacamos: a prótese fixa mais/menos utilizada é a cimento aparafusada (47,0%) e a cimentada (1,5%), respetivamente; a zircónia com recobrimento vestibular é a mais utilizada no setor anterior, e a zircónia monolítica pintada no setor posterior, neste tipo de prótese; ainda neste tipo de prótese, o chipping é o pedido mais frequente de reparação; já na prótese removível a complicação mais frequente é a fratura da base/dentes ou perda destes. Conclusão: A prótese fixa sobre implantes mais requerida é a cimento-aparafusada e o material mais utilizado no setor anterior e posterior é a zircónia com recobrimento vestibular e a zircónia monolítica pintada, respetivamente. Os registos de mordida imprecisos são um desafio muito reportado pelos técnicos, e o chipping a maior complicação na prótese fixa. Na prótese removível, o sistema tipo Locator® é o mais utilizado, e a maior complicação são as fraturas da base/dentes, ou perda de dentes.
lntroduction: ln edentulous patients, oral rehabilitation can be performed through implant-supported prosthesis. There are several clinica! and laboratory steps that comprise this process, each of them has a specific role in the success of the treatment. ln this investigation we intend to analyze the main options, complications/limitations in this type of prosthesis, reported by the Dental Technicians. Material and Methods: The data of this investigation was collected through a questionnaire applied to Dental Prosthesis Technicians in Portugal, developed on Qualtrics® platform and distributed in 2 ways: via e-mail with laboratories and respective Dental Prosthetics Technicians, and a request for disclosure sent to the Portuguese Association of Dental Prosthesis Technicians. Results: 190 questionnaires were considered valid. lt was found that 64% of Dental Technicians perform both fixed and removable-supported prosthesis. 25,3% only fixes prosthesis and 1O,7% only removable prosthesis. From the results obtained we highlight the following: the fixed prosthesis more/less applied is a screwed cement (47,0%) and a cemented one (1,5%), respectively; zirconia with vestibular covering is more used in the anterior sector, and a monolithic zirconia painted is more used in the posterior sector, in this type of prosthesis; also in this type of prosthesis, chipping is the most frequent request for repair; also, the most prevalente complication in removable prosthesis is the base/teeth fracture or loss. Conclusion: The most requested implant-supported prosthesis is screw-cement and the material mostly used is zirconia with vestibular covering for the anterior sector and painted monolithic zirconia for the posterior sector. lnaccurate interocclusal records are a challenge often reported by technicians. And chipping is the biggest complication in fixed prosthesis. ln removavel prothesis, the Locator® type system is the most used and the biggest complication is fractures of the base/teeth and the loss of teeth.
