Abstract

L'implant prothétique comporte une première partie principale présentant une face de réception et une partie additionnelle qui est destinée à être rigidement attachée à la face de réception. La face de réception comporte au moins un trou présentant une ouverture 17 et une paroi interne 15 ayant le profil d'un cône retourné de façon telle que le trou aille en s'élargissant en direction de l'intérieur de l'implant, et la partie additionnelle 20 comporte un substrat 22 avec des première et seconde faces, au moins un tenon adapté pour pénétrer dans la perforation 14 qui comporte un moyen pour déformer le tenon dès que l'on introduit ce dernier dans le trou, de manière telle que le tenon soit évasé et donc qu'une partie de sa longueur devienne plus large que l'ouverture du trou, afin que soit assurée une fixation résistant à une tentative de séparation de la seconde partie additionnelle et de la première partie principale de l'implant 1.The prosthetic implant comprises a first main part having a receiving face and an additional part which is intended to be rigidly attached to the receiving face. The receiving face has at least one hole having an opening 17 and an internal wall 15 having the profile of a cone turned over so that the hole widens towards the interior of the implant, and the additional part 20 comprises a substrate 22 with first and second faces, at least one stud adapted to penetrate the perforation 14 which comprises means for deforming the stud as soon as the latter is introduced into the hole, so that the post is flared and therefore a part of its length becomes wider than the opening of the hole, so that a fixation resistant to an attempt to separate the second additional part and the first main part of the implant 1 is ensured .
