One aspect of the invention concerns a one-piece endosteal dental implant (10). The implant (10) has a root portion (12) which is externally threaded for engagement in a hole formed in a supporting bone structure. The implant also has an abutment (14) for supporting a dental prosthesis. The abutment is formed in one piece with the root portion and has a central axis (22) which is inclined at an acute angle to the central axis (20) of the root portion. The abutment includes a formation (26) which can be engaged by an implant driving tool (28) operable to engage the root portion in the supporting bone structure. Other aspects of the invention concern a dental implantation apparatus that includes the dental implant and driving tool in combination and the driving tool itself. |
