Resumo(s)
Em Portugal, o número de desdentados parciais reabilitados com próteses removíveis é superior aos reabilitados com próteses fixas. As próteses parciais removíveis (PPR) acrílicas são utilizadas há várias décadas para reabilitar os pacientes desdentados parciais. A produção de PPR através do fluxo de trabalho convencional implica várias etapas clínicas e laboratoriais de elevada precisão, minúcia e tempo tornando este processo suscetível de ser afetado por erros humanos.
A introdução do CAD-CAM na Medicina Dentária, e mais recentemente na Prostodontia Removível, pode simplificar o processo de realização das próteses e torná-lo mais rápido, eficaz e económico.
O presente caso clínico tem como objetivo compreender os desafios clínicos e laboratoriais associados à execução de uma PPR não metálica, através de um fluxo digital total. Adicionalmente, pretende-se avaliar o desempenho clínico da reabilitação por um período de 5 anos. Para a realização deste caso clínico foi selecionado um paciente com os tratamentos pré- protéticos realizados, com indicação para ser reabilitado com PPR acrílica, que consentisse os registos fotográficos para fins académicos e que garantisse assiduidade em consultas de controlo anual por um período de 5 anos.
A impressão foi realizada com recurso a um scanner intraoral, o desenho foi produzido por softwares CAD e a reabilitação foi impressa por uma impressora tridimensional, recorrendo aos Laboratórios Digitech® e à Pós-Graduação em Tecnologias Digitais em Prótese Dentária da Faculdade de Medicina Dentária da Universidade de Lisboa.
O resultado foi a conclusão de próteses que cumprem os critérios funcionais e estéticos, permitindo que o paciente ficasse bastante agradado com o resultado alcançado.
In Portugal, the number of partially edentulous patients rehabilitated with removable prostheses is higher than those rehabilitated with fixed prostheses. Acrylic removable partial dentures (RPDs) have been used for several decades to rehabilitate partially edentulous patients. The conventional workflow for producing RPDs involves multiple clinical and laboratory steps that require high precision, attention to detail, and time. Therefore, this process is very susceptible to human errors. The introduction of CAD-CAM technology in Dentistry, particularly in Removable Prosthodontics, can streamline the prosthesis fabrication process, making it faster, more efficient, and cost-effective. This clinical case explores the clinical and laboratory challenges of creating a non-metallic RPD using a fully digital workflow. Additionally, the clinical performance of the rehabilitation will be evaluated over a 5-year period. For this clinical case, a patient who had undergone pre- prosthetic treatments was selected. The patient was indicated for acrylic RPD rehabilitation, agreed to provide photographic records for academic purposes, and committed to annual follow-up appointments for 5 years. The intraoral scan was performed using an intraoral scanner, and the design was created using CAD software. The rehabilitation was 3D printed by using the Digitech® laboratories and the Postgraduate Program in Digital Technologies in Dental Prosthetics at the Faculty of Dental Medicine, University of Lisbon. The result was the successful fabrication of prostheses that meet both functional and aesthetic criteria, leaving the patient highly satisfied with the achieved outcome.
