Abstract

La présente invention concerne un implant dentaire associé à une dent artificielle. Une dent artificielle de type butée comprend les éléments suivants : une prothèse montée sur un accessoire possédant un orifice d'arbre formé dans sa partie intérieure et implantée dans un os de mâchoire, et une partie de montage supérieure ; et une partie de tige de fixation inférieure insérée dans l'orifice d'arbre de l'accessoire afin d'être combinée de manière élastique audit accessoire. Une partie tampon d'impact destinée à amortir plus efficacement l'impact dû à la pression externe latérale ou à une force occlusale dans diverses directions est prévue sur une butée ; une partie de fixation élastique devant être combinée de manière élastique à l'accessoire est prévue sur la partie inférieure de la partie tampon d'impact ; et la durabilité d'une partie fixée de manière élastique est maintenue de manière semi-permanente, indépendamment d'une force occlusale exercée dans diverses directions en raison de nombreuses occlusions répétées dues à la séparation de la partie tampon d'impact et de la partie de fixation élastique. Ainsi, il est possible d'accroître considérablement la durée de vie d'un implant et de faciliter l'implantation.
