Surgical guide system for dental implantology, comprising a plate (10) provided with one or more guide sleeves (2) delimiting corresponding through holes whose axes are oriented according to predetermined directions, and a drill (4) for osteotomy having a spindle that can be connected to a handpiece or similar tool and a drilling head or drilling portion (41), the drill (4) being apt to be associated to each of the guide sleeves (2) during an osteotomy step, the guide sleeves (2) having an occlusal side (2D) and a gingival side (2G). The diameter (d41) of the drilling head or portion (41) of the drill (4) is larger than the inner diameter (d2) of said one or more guide sleeves (2) while the spindle of the same drill (4) is of smaller diameter, such that the association of the drill (4) to any of the guide sleeves (2) can be performed only by inserting its spindle through the gingival side of the sleeves, and when the drill (4) is associated with any of the sleeves (2), the drilling head (41) of the drill (4) is protruding from the gingival side (2G) thereof. The surgical guide has a void (100) in which the drilling head (41) of the drill (4) can be accommodated. |
