Abstract

La présente invention concerne un implant utilisant un filetage sans vis dans un trou de placement de corps d'implant dans un os alvéolaire, et un procédé chirurgical pour l'implant, le corps d'implant qui est placé dans un trou de placement de corps d'implant comprenant : une paire de corps d'implant séparés formés chacun dans une forme d'arc en colonne et ayant des filetages sur leur surface interne et une plaque d'accrochage en forme de croissant vers l'extérieur depuis la partie inférieure de telle sorte que, pendant l'insertion face à face dans le trou de placement de corps d'implant, les plaques d'accrochage en forme de croissant s'accrochent dans des rainures d'accrochage en forme d'arc sur les deux côtés de la surface inférieure du trou de placement de corps d'implant; un corps d'implant intégré disposé entre la paire de corps d'implant séparés et comprenant deux colonnes en forme d'arc ayant chacune des filetages sur leur surface interne et, avec les colonnes face à face, ayant les parties inférieures reliées par un disque; et une butée de type boulon ou vis sur la partie supérieure de laquelle une couronne est fixée à demeure, et ayant une forme assemblée d'un cylindre unique à l'intérieur du trou de placement de corps d'implant. En conséquence, la présente invention peut prolonger la durée de vie de manière significative, réduire des effets indésirables puisqu'une opération chirurgicale est possible avec un trou de placement de corps d'implant peu profond, prolonger la durée de vie d'un implant étant donné que les charges répétées de mastication d'aliments sont dispersées et, en outre, éliminer la nécessité d'une greffe osseuse artificielle pendant une opération d'élévation sinusale, et réduire au minimum le risque de lésions nerveuses dans le cas de molaires mandibulaires.
