摘要：
The present invention proposes a guide system for drilling at least one dental implant housing (30), including a dental hand component (10) comprising a handle (12) with an end having a head (14) that secures a drill bit (16) having a tip (161) and a geometric axis (B). The system also guides a surgical guide (20) for alignment of the geometric axis (B) of the drill bit (16) with a geometric axis (L) of at least one housing (30), in accordance with a pre-defined position, to be drilled in a respective implant space (E1, E1') of a patient, said surgical guide (20) comprising a base (22) that has a fitting surface (222) with geometry suited to fitting over at least part of a dentition region (D) of the patient, and an opposite surface (224). According to the present invention, the head (14) of the hand part (10) comprises a hand part guide (18, 18') having walls that define a guide groove (182) in the form of an arc, said guide groove (182) being concentric with and parallel to the geometric axis (B) of the drill bit (16). The base (22) of the surgical guide (20) comprises at least one guide wall (24, 24'a, 24'b) in the form of an arc extending from the opposite surface (224), said guide wall (24, 24'a, 24'b) being concentric with and parallel to the geometric axis (L) of the housing (30), the guide groove (182) of the hand part guide (18, 18') being insertable around the guide wall (24) of the surgical guide (24, 24'a, 24'b).La présente invention concerne un système de guidage pour la réalisation par perforation d'au moins un logement (30) d'implant dentaire, comprenant une pièce à main dentaire (10) comportant un manche (12) avec une extrémité possédant une tête (14) assurant la fixation d'une mèche (16) présentant une pointe (161) et un axe géométrique (B). Le système de guidage comprend également un guide chirurgical (20) pour l'alignement de l'axe géométrique (B) de la mèche (16) avec un axe géométrique (L) d'au moins un logement (30), selon une position prédéfin
