Prothèse adjointe partielle : occlusion, choix et montage des dents. Polymérisation des bases

Abstract

Success of a treatment with removable partial denture (RPD) essentially depends on the occlusal integration of the different prosthetic constructions realised according to the treatment planning intially defined. An articulator’s set-up of the plaster models is necessary as far for the case’s study as for the prosthetic realisation and information’s transmission to the technician. Considering the gaptoothed situation, a different reference is to be chosen : dental reference : the maximal intercuspidian occlusion (MOI) or articular : the centric relation. Different materials can be used. Choice of impression’s techniques is important, particularly for the realisation of mixed prosthesis. Tooth choice and tooth placement are important stages for the future esthetic integration of the RPD. Patients wishes must be considered and also remaining teeth and dentogenics, described by Frush and Fisher. It is also possible to make up the resin and porcelaine teeth. Techniques are described in this article. Tooth placement will be facilitated by the pre and pro-prosthetic preparations intra and inter arch, which will restore satisfaying compensation curves. Polymerisation and finition are finally important laboratory’s stages which must not be neglected. Resin properties are briefly reminded. The final purpose is to obtain RPD that combines esthetic in visible parts and prophylaxis in posterior areas.
