Abstract

La présente invention concerne un implant capable d'empêcher la force appliquée à une butée d'agir aisément sur une partie d'extrémité supérieure d'une fixation d'implant et en conséquence capable de supprimer une ischémie dans les gencives lorsqu'il est utilisé chez un patient. La présente invention concerne spécifiquement un implant dentaire (10) qui comprend une fixation d'implant (12) imbriquée dans un os alvéolaire d'un patient, une butée (14) fixée à une partie d'extrémité de la fixation (12), et une couronne prosthétique dentaire (18) fixée à une partie supérieure (14b) de la butée (14). La fixation (12) a un trou (12b) dans lequel une base (14a) de la butée (14) est ajustée et fixée, et la largeur de la base (14a) de la butée (14) mesure de la moitié à un dixième de celle de la partie supérieure de la fixation (12).
