Abstract:
1. A dental implant drilling system for implanting a dental implant in bone tissue using an implant drill driver, comprising: a shank removably coupleable to the implant drill driver, the shank comprising a circumferentially enclosed internal passage having a non-round cross-sectional shape and a driver engagement portion comprising a first notched section, wherein when coupled to the implant drill driver, the shank is rotatable via operation of the implant drill driver; a drill guide pin comprising a bone penetrating end portion, a shank engagement end portion opposing the bone penetrating end portion, and an elongate shaft, the shank engagement portion comprising a second notched section having a non-round cross-sectional shape corresponding with the non-round cross-sectional shape of the internal passage of the shank, wherein the elongate shaft extends between the bone penetrating end portion and the second notched section, and wherein an intersection of the second notched section and elongate shaft comprises a stop that engages the shank to prevent axial movement of the drill guide pin relative to the shank; and a cannulated drill bit, wherein the drill guide pin is configured to receive thereabout the cannulated drill bit, and wherein the cannulated drill bit is removably coupleable to the implant drill driver; wherein the second notched section of the shank engagement portion is removably insertable within the internal passage of the shank, and wherein when the second notched section is inserted within the internal passage of the shank, engagement between the second notched section and the internal passage facilitates co-rotation of the shank and drill guide pin.
