Each central axis of a female screw part 102 and a fitted part 103 of a fixture 100 as a dental implant is positioned on a central axis O of the fixture 100. When the first pin 1 and the second pin 2 are inserted to an insertion hole 33 of the angle correction member 3, respectively, each rotation axis S1, S2 of the first pin 1 and the second pin 2 fixes the angle correction member 3 on a placing part 43 of the stent 4 by the fixing means 5 in an angle positioned on the same straight line as the central axis O of the fixture 100.SELECTED DRAWING: Figure 1 |
