Abstract(s)
Uma prótese dentária total removível é um dispositivo protético artificial que substitui toda a dentição e estruturas anexas da maxila ou da mandíbula. É consensual que para se obter uma prótese total removível bem-sucedida, é necessário ter-se suporte, estabilidade e retenção. Para isso, são vários os passos importantes na elaboração das próteses, desde uma impressão preliminar adequada que permita construir as moldeiras individuais, a realização de selamento periférico da moldeira individual e impressões definitivas com detalhe e precisão ótimos. Um selamento periférico e uma extensão da prótese total removível adequados ajudam a conseguir uma “tríade de equilíbrio”, caracterizada por boa retenção, suporte e estabilidade.
O objetivo deste estudo foi identificar quais as tendências atuais nas impressões em prótese total realizadas nas pós-graduações em Prostodontia na Península Ibérica; determinar quais as técnicas de impressão mais utilizadas e determinar quais os biomateriais mais frequentemente usados, através de um questionário enviado por correio eletrónico aos responsáveis de pós-graduações no âmbito da Prostodontia na Península Ibérica. O questionário consistiu em 24 perguntas, divididas em duas partes.
Apesar de ter havido limitações decorrentes da falta de algumas respostas a certas perguntas, que podem ter tido influência na possível inferência estatística dos resultados deste inquérito, foi possível verificar que: em grande parte, as técnicas e materiais utilizados são semelhantes entre Portugal e Espanha. No entanto, verificou-se que existem algumas diferenças, como por exemplo o tipo de moldeira utilizada nas impressões preliminares e o material utilizado para a realização da impressão definitiva. Não sendo conhecidos estudos deste tipo na Península Ibérica, verificou-se que a grande maioria das técnicas e materiais utilizados na Península Ibérica são semelhantes aos encontrados em pós-graduações na área de Prostodontia nos EUA.
A complete denture is an artificial prosthetic device that replaces the entire dentition and associated structures of the maxilla or the mandible. There exists consensus that to obtain a successful complete denture it is necessary to have support, stability and retention. It starts from an adequate preliminary impression, that allows building the individual trays, performing peripheral sealing of the individual tray to final impressions with great detail and accuracy. A peripheral sealing and an adequate extension of removable prostheses helps to acomplish a “triad of equilibrium” characterised by good retention, support and stability. The aim of this study was to identify the current trends in impressions for complete dentures made in post-graduate programs in Prosthodontics in the Iberian Peninsula; establishing the most used impression techniques as well as establishing which biomaterials are the most frequently used, through a survey sent by e-mail to postgraduate directors in Prosthodontics in Iberian Peninsula. This survey comprised 24 questions, divided into two parts. Although there have been limitations due to the lack of some answers to certain questions, which may have had an influence on the possible statistical inference of the results of this survey, it was found that: largely, the techniques and materials used were similar both in Portugal and Spain. Nevertheless, it was found that there are some differences, such as the type of tray used in the preliminary impression and the material used for final impressions. There aren’t any studies of this kind in the Iberian Peninsula and from the academic point of view it was found that most of the techniques and materials used in the Iberian Peninsula are similar to those found in the postgraduate prosthodontic programs in the United States of America.
