At the same time, the first positioning taper portion 121 and the second positioning taper portion 231 increase the supporting contact area between the abutment tooth holder 1 and the implant holder 2, thereby dispersing the contact stress and prolonging the present. The life of the creation. Moreover, due to the tapered surface design of the second positioning taper portion 231, and the opening 230 has a relatively large aperture, the abutment connecting end 12 can be guided by the tapered surface when being inserted into the inner hole 23, Excellent convenience in assembly alignment. Furthermore, the first fitting portion 122 and the second fitting portion 232 of the present invention all correspond to a geometric polygonal structure selected to be non-circular, thereby preventing the -9 - M391380 abutment 1 from opposing the implant The effect of the rotation of the body seat 2. In addition, the gingival cone portion 11 and the first positioning cone portion 121 of the present invention have two different tapers, and the second taper θ2 is smaller than the first taper Θ of the gingival cone portion 11 by a two-stage taper design After the abutment connecting end 12 is correspondingly embedded in the inner hole 23, the gingival cone portion 11 can further prevent the abutment connecting end 12 from being excessively forced into the inner hole 23, thereby improving the assembly accuracy. Although the present invention has been disclosed by the above-described preferred embodiments, it is not intended to limit the present invention. Any modifications and modifications to the above embodiments may be made without departing from the spirit and scope of the present invention. The technical scope protected by this creation, therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached. — — 10 — [Simple description of the diagram] Figure 1 is an exploded view of the root implant of H.
