Abstract(s)
Com o envelhecimento da população, é cada vez maior o recurso a prótese dentária total. Para a execução de uma prótese adequada, é necessário um registo intermaxilar preciso, para maximizar resultados estéticos e funcionais. Existem diferentes métodos para medição da dimensão vertical no registo intermaxilar. Com este trabalho pretende-se avaliar a adequabilidade dos diferentes métodos disponíveis para avaliação da dimensão vertical de oclusão, de repouso e espaço livre funcional. Apesar dos métodos baseados em medições crânio-faciais ou em cefalogramas serem amplamente utilizados, não existe um método que apresente vantagens claras sobre os restantes. No contexto da prótese total, a determinação da dimensão vertical mais adequada deverá ser obtida pela conjugação de vários métodos. O desenvolvimento tecnológico permite atualmente utilizar métodos computorizados como auxílio à determinação das relações intermaxilares, por forma a minimizar o tempo de execução e os possíveis erros associados à medição.
Regarding an increasingly older population, the need for total dental prosthetics is rising. In order to effectively produce an adequate prothesis, an accurate intermaxillary record is of the upmost importance, allowing the maximization of aesthetic and functional outcomes. There are several different methods for determining vertical dimension. With the current study we aim to assess which methods are adequate for assessing vertical dimension in occlusion, vertical dimension at rest and freeway space. Although the methods that are based on cranial and facial measurements or on measures in cephalograms are the most frequently used, there is no method that has been proved superior. Considering total dental prosthesis, an accurate determination of the vertical dimension should be obtained with a combination of different methods. The recent technological advances allow the use of computed methods as an aid to determine the intermaxillary relations, and can therefore be less time-consuming and limit errors potentially associated to physical measurements.
