The drill set has two drills (2,3) with respective diameters (d2,d5) at a point of cutting blades (3a,3b) equal to a diameter (D3) of a tip end of a fixture (1). The drills have diameters (d1,d3) at a back end of the blades equal to a maximum root diameter of a male screw (1e) on an oral side cavity. A length of the blades is larger than an entire length (L1) of the fixture. Both the blades form a two-step taper shape. |
