The shank is removably coupleable to the implant drill driver and includes an internal passage that has a non-round cross-sectional shape. When coupled to the implant drill driver, the shank is rotatable via operation of the implant drill driver. The drill guide pin includes a bone penetrating end portion and a shank engagement portion. The shank engagement portion includes a notched section having a non-round cross-sectional shape corresponding with the non-round cross-sectional shape of the internal passage of the shank. The notched section of the shank engagement portion is insertable within the internal passage of the shank. Moreover, engagement between the notched section and the internal passage facilitates co-rotation of the shank and drill guide pin. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The dental implant drilling system of claim 1, wherein the non-round cross-sectional shape of the internal passage and the second notched section of the shank engagement portion is a generally D-shape. ### Claim 3 (depends on 1) The dental implant drilling system of claim 1, wherein the shank comprises a first driver coupling feature and the cannulated drill bit comprises a second driver coupling feature, and wherein the first and second driver coupling features are identical. ### Claim 4 (depends on 1) The dental implant drilling system of claim 1, wherein the second notched section of the shank engagement portion extends lengthwise along only a portion of the drill guide pin. ### Claim 5 (depends on 1) The dental implant drilling system of claim 1, wherein the internal passage extends axially through the shank from a first end of the shank to a second end of the shank. ### Claim 6 (depends on 1) The dental implant drilling system of claim 1, wherein a cross-sectional size of the second notched section of the shank engagement portion is smaller than a cross-sectional size of the internal passage of the shank. ### Claim 7 (depends on 1) The dental implant drilling system of claim 1, wherein the elongate shaft comprises a series of markings indicating a depth of the guide pin in bone tissue. ### Claim 8 (depends on 1) The dental implant drilling system of claim 1, wherein the second notched section has a cross-sectional area smaller than a cross-sectional area of the elongate shaft. ### Claim 9 (depends on 1) The dental implant drilling system of claim 1, wherein an outer surface of the elongate shaft is smooth. ### Claim 10 (depends on 9) The dental implant drilling system of claim 9, wherein the bone penetrating end portion comprises a pointed tip. ### Claim 11 (depends on 1) The dental implant drilling system of claim 1, wherein the guide pin is fluteless. ### Claim 12 A method for drilling bone tissue, comprising: removably coupling a shank to a bone drill driver, the shank comprising an internal passage having circumferentially enclosed non-round cross-sectional shape extending an entire length of the shank and a driver engagement portion comprising a notched section; inserting a shank engagement portion of a guide pin into the internal passage of the shank until a stop formed in the guide pin contacts an end of the shank to prevent further axial movement of the guide pin along the internal passage, the shank engagement portion comprising a keyed-in section having a non-round cross-sectional shape matching the non-round cross-sectional shape of the internal passage of the shank; with the keyed-in section inserted within the internal passage of the shank, co-rotating the shank and the guide pin via actuation of the bone drill driver and engagement between the keyed-in section of the shank engagement portion of the guide pin and the internal passage of the shank; driving the guide pin into bone tissue; removing the shank engagement portion of the guide pin from the internal passage of the shank; decoupling the shank from the bone drill driver; removably coupling a cannulated drill bit to the bone drill driver; positioning the guide pin through the cannulated drill bit; rotating the cannulated drill bit via actuation of the bone drill driver; and driving the cannulated drill bit into bone tissue surrounding the guide pin. ### Claim 13 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; and 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, 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 wherein the guide pin is fluteless; 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.
