Abstract

L'invention concerne une fixation pour implant dentaire. Selon l'invention, ladite fixation pour implant dentaire comprend : un premier corps qui est implanté dans la zone inférieure d'un trou de forage percé dans l'os alvéolaire de la cavité orale, de sorte que la ligne virtuelle reliant les filetages mâles formés sur la surface extérieure du premier corps est sensiblement parallèle à la ligne axiale du trou de forage ; et un second corps dont le diamètre est plus grand que celui de la section transversale du premier corps, qui présente une surface extérieure sur laquelle les filetages mâles sont formés en une ligne de vissage sensiblement identique à celle des filetages mâles du premier corps, qui s'étend à partir de la partie supérieure du premier corps et est implantée dans la zone supérieure du trou de forage. La fixation de l'invention ne peut se déplacer lorsqu'elle est initialement implantée dans le trou de forage foré dans l'os alvéolaire, ce qui permet de la maintenir dans une direction parallèle à la ligne axiale du trou de forage, et empêche à l'avance l'échec de pose de l'implant. La fixation de l'invention présente une force de fixation maximum lorsqu'elle est implantée qui l'empêche de se déplacer, ce qui pourrait autrement se produire après l'implantation, et assure la stabilité des implants dentaires.
