Abutment free of adhesive joint and dentition defect implant upper portion repair device

Abstract

The invention provides an abutment free of adhesive joint and a dentition defect implant upper portion repair device. The abutment free of adhesive joint comprises a hollow implant connection portion and a hollow Morse's taper abutment body, the implant connection portion and the hollow Morse's taper abutment body which is positioned at the top end of the implant connection portion are integrated, and the external diameter of the Morse's taper abutment body is gradually increased from the top end to the bottom end. The Morse's taper abutment body is provided with at least one cutting groove with the height smaller than or equal to half of that of the Morse's taper abutment body. An included angle between the axis of the implant connection portion and the axis of the Morse's taper abutment body is 0-30 degrees, and the Morse's taper abutment body is 0-5 degrees in Morse's taper, 3-6mm in external diameter and 3-8mm in height. By adoption of the Morse's taper abutment body for dental crown connection, adhesion or screw retaining for connection is avoided, simplicity in processing and convenience and quickness in connection are realized, and inflection caused by utilization of adhesives is avoided.

Description

technical field [0001] The invention relates to the technical field of restoration devices for missing dentition, in particular to an abutment without an adhesive connection and a restoration device for the upper part of an implant for missing dentition. Background technique [0002] After the existing abutment is screwed to the implant, the following two methods are usually used to realize the connection with the crown. One is screw retention. When screw retention is used, there are screw holes in the crown, which affects the appearance of the crown. The other is through bonding and retention, which requires the use of adhesives, that is, the crown is bonded to the abutment by bonding to achieve the repair of missing dentition, but through bonding If the connection is realized in a direct way, it is easy to cause the adhesive to overflow and infect the gums. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] I...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies of the prior art above, the purpose of the present invention is to provide an abutment without adhesive connection and an implant upper restoration device for missing dentition. When the crown is fixed on the abutment, it will affect the integrity of the crown, or the adhesive will overflow and easily infect the gums
