Method for attaching a dental fixture in bone tissue

A method for attaching a fixture for holding a dental prosthesis or bridge to a jaw bone and a zygomatic bone, said method including steps of:

• (a) making a first hole of a first diameter in the jaw bone,
• (b) making a second hole of a second diameter in the zygomatic bone in axial alignment with the first hole, with the second diameter being smaller than the first diameter,
• (c) inserting a fixture having first and second external threads adapted to the respective first and second diameters, said first external threads being relatively close to one end of the fixture and said second external threads being remote from said one end and said fixture having its other end disposed at a substantial distance from the first external threads,
• (d) during inserting of said fixture said other end being moved axially through said first hole and then entering said second hole,
• (e) simultaneous screwing-on of the fixture with the first and second external threads being in the respective first and second holes,
• (f) orienting the fixture while same is being screwed-on by rotating the fixture around its longitudinal axis, thereby operatively positioning a bore that is in the fixture at said one end thereof, said bore having internal threads for mounting a dental prosthesis or a bridge on the fixture, with internal threads being in a tilt position with respect to the longitudinal axis of the fixture such as to permit anatomically correct positioning of a dental prosthesis or bridge that is mounted on said fixture, and
• (g) mounting the dental prosthesis or the bridge on the fixture by threadably engaging said internal threads with external threads on the dental prosthesis or the bridge.
