Abstract

L'invention concerne un ensemble foret pour opérations d'implantation. L'ensemble foret de l'invention comprend un corps de perçage de forme cylindrique creuse présentant une partie supérieure dotée d'un organe de découpe, et une unité de vis femelle disposée sur une paroi intérieure du corps de perçage pour recevoir une partie d'os alvéolaire séparée de dernier pendant le perçage dudit os alvéolaire. L'invention permet d'exécuter facilement des procédés de perçage d'os alvéolaire et d'éliminer facilement des fragments d'os alvéolaire pendant son perçage, ce qui raccourcit la durée requise pour percer l'os alvéolaire.
