Abstract

La présente invention concerne un dispositif de guidage de placement pour un implant dentaire. Le dispositif de guidage de placement pour un implant dentaire comprend : un foret d'actionnement d'implant dentaire comprenant une partie lame de forage qui fait saillie dans la direction vers l'os alvéolaire de telle sorte que le forage peut être effectué dans la direction verticale entre des dents adjacentes et a une surface inférieure qui vient en contact avec la surface de l'os alvéolaire ; et une partie de guidage qui est couplée de manière sélective et fixe à au moins une partie de la surface extérieure du foret d'actionnement d'implant dentaire de sorte qu'au moins une partie de la partie lame de forage puisse être exposée, le foret d'actionnement d'implant dentaire comprenant : une partie de verrouillage qui est formée sous une forme cylindrique ayant un certain diamètre et comporte une ou plusieurs rainures de verrouillage qui sont formées dans la surface circonférentielle externe pour être espacées à certains intervalles de telle sorte que la partie de guidage est couplée de façon sélective et fixe à la ou aux rainures de verrouillage, et la partie de guidage comprenant : une partie de guidage interne comprenant une partie corps ayant un premier diamètre et ayant une forme cylindrique s'étendant dans la direction longitudinale, une partie col ayant un deuxième diamètre et s'étendant à partir d'une partie d'extrémité de la partie corps dans la direction longitudinale, et une partie d'extension ayant un troisième diamètre et s'étendant à partir de l'autre partie d'extrémité de la partie corps dans la direction longitudinale ; et une partie de guidage externe qui est formée pour entourer la surface externe de la partie de guidage interne et est couplée à la partie d'extension. La partie de guidage externe peut comprendre une partie d'espace espacée d'une certaine distance de la partie corps et de la surface externe de la partie col ; et une partie étagée qui est disposée sur la partie d'extrémité inférieure de la partie de guidage externe et fait saillie vers la surface interne à partir de la partie d'extrémité inférieure.
