Abstract

L'invention a pour objet un procédé et un appareil de détermination des caractéristiques d'occlusion de dentures. On soumet aux forces d'occlusion des éléments en un matériau qui présente une mémoire photo-élastique et on analyse, à l'aide d'un polariscope, les résultats des empreintes obtenues. Le procédé et le dispositif selon l'invention permettent une analyse qualitative et quantitative, notamment de dentures humaines ainsi que la conservation des résultats de l'analyse sur des enregistrements permanents.The subject of the invention is a method and an apparatus for determining the occlusion characteristics of teeth. Elements of a material which has a photoelastic memory are subjected to the forces of occlusion and the results of the imprints obtained are analyzed using a polariscope. The method and the device according to the invention allow a qualitative and quantitative analysis, in particular of human teeth as well as the conservation of the results of the analysis on permanent records.
