Furthermore, it disperses excessive stress on surrounding supportive bone tissue and helps stabilize teeth.

Abstract

L'invention concerne un ensemble foret pour soulever une membrane sinusienne. L'ensemble foret de l'invention permet de soulever une membrane sinusienne positionnée à l'intérieur d'un os alvéolaire après son perçage pour implanter un implant. Ledit ensemble foret comprend un foret pour percer l'os alvéolaire, constitué d'un corps de perçage possédant une extrémité dotée d'un organe de découpe pour percer l'os alvéolaire, l'autre extrémité comprenant un trou traversant; et d'une tige de perçage couplée au corps de perçage orientée vers le trou traversant dudit corps de perçage de sorte que ladite tige de forage s'approche de l'extrémité du corps de perçage et s'en écarte, et règle la profondeur percée de l'os alvéolaire pendant le perçage. Selon l'invention, des procédés de perçage d'os alvéolaire pour une opération d'implantation sont exécutés séquentiellement par une pluralité de forets afin de former des trous durs dans l'os alvéolaire, et une membrane sinusienne est soulevée de manière stable pour empêcher son endommagement, ce qui permet d'améliorer la fiabilité de l'opération d'implantation.
