Abstract

The present invention relates to a dental implant, and more particularly, to a dental implant in which a fixture and an abutment are together by a separate screw post so as to prevent the breakage of an implant screw tightening part and uniformly transmit forces over the entirety of a contact surface, to thereby prevent stresses from being partially concentrated, and in which the screw-tightening direction between the fixture and the abutment is variable so as to improve the coupling force between the fixture and the abutment and fundamentally prevent a screw from becoming loosened. The dental implant of the present invention comprises said fixture and abutment, the abutment including a lower abutment to be fitted onto the fixture, and an upper abutment connected to an upper portion of the lower abutment, the lower abutment and the upper abutment being separate from each other. The upper abutment and the fixture are coupled and fixed by the screw post.

Description

technical field

[0001] The present invention relates to a dental implant, in particular to a method of combining a retaining screw and an abutment by using a separate screw column, thereby preventing the screw joint of the implant from being broken, and at the same time transmitting force uniformly to the entire contact surface, preventing stress on the part The phenomenon of concentration, moreover, make the direction of the screw combination between the retaining nail and the abutment reverse, improve the bonding force between the retaining nail and the abutment, and fundamentally solve the problem of the dental implant with the screw untwisted. Background technique

[0002] Generally speaking, an implant refers to an artificial substitute that can reproduce the same shape and function as a natural tooth, and its structure is as follows: figure 1 As shown, it includes: a titanium fixture (fixture) 10, the outer peripheral surface of which forms a thread 11 to be set on the...
