Abstract

L'invention porte sur un implant dentaire qui présente une plaque, l'implant dentaire comprenant une plaque dont la forme correspond à la surface extérieure d'un os alvéolaire d'un être humain et dont la surface inférieure est en contact avec l'os alvéolaire ; une pluralité d'éléments de fixation destinés à fixer la plaque à l'os alvéolaire ; une dent artificielle disposée sur la plaque, et une structure couplée destinée à fixer la dent artificielle à la plaque. Grâce à l'implant dentaire, une opération simple d'insertion d'implant est possible par fixation de la plaque à un os alvéolaire d'un patient, qui ne mastique pas normalement en raison de l'absence d'une dent naturelle et, en particulier, qui présente une quantité insuffisante d'os ou une qualité inférieure des os, de telle sorte qu'un implant classique ne peut pas être implanté chez le patient.
