Abstract
We developed a new insertion technique of fixture for Apatite 2-Piece Implant with the idea that the proper implant placement is essential for both the prosthetic design and long-term prognosis. This paper presents the new technique and its efficiency.
The technique is as follows: About one month before the fixture placement, the pilot hole (PH) with a diameter of 1 mm is made in the bone using a pesso reamer and a diagnostic denture. The direction and site of the PH is defined as the long axis and the center of the artificial tooth which is arranged in the denture. Upon surgical operation of the fixture placement, the trephin guide pin is inserted into the PH and the trephin bur is inserted onto the head of the pin. Anyone, even a beginner, can form the proper implant channel without any trouble by our technique. It was validated by the simulation experiment that the technique was efficient for the precision in the implant placement.
