Description

Technical Field

[0001] The utility model relates to the field of dental implantation, in particular to a dental implantation abutment positioning device. Background Art

[0002] Dental implant abutment refers to the component that connects the implant and the artificial crown during dental implant surgery, usually used to support and stabilize the artificial crown;

[0003] In order to prevent the dental implant abutment and the implant from loosening, the bottom of the dental implant abutment is generally designed to be a spiral structure, so that the bottom of the abutment and the implant can be tightened to prevent loosening.

[0004] However, the threaded connection method is easily affected by friction in actual use, causing the dental implant abutment to rotate. The connection and positioning between the abutment and the implant are not tight enough, which can easily cause the dental implant abutment and the implant to shift and loosen, affecting the service life of the dental implant. For this reason, we propose a dental implant abutment positioning device. Utility Model Content

By setting a positioning component, when the abutment body and the implant body are installed, the positioning piece is inserted into the corresponding positioning groove, and the abutment body and the implant body can be preliminarily positioned. Then, a plurality of locking bolts are used to pass through the corresponding screw hole one and screw hole two in sequence, and the corresponding positioning piece and the positioning groove are locked. Then, the nut is tightened to firmly connect the abutment body and the implant body together. The plurality of locking bolts and locking nuts are evenly distributed, and multiple positions of the connection can be fixed. Even if the connection is affected by the bite force or friction force during use, the connection is not easy to rotate or loosen.
