A wrench that cooperates with a healing abutment

Abstract

The invention discloses a healing abutment, which comprises an abutment main body, the abutment main body is a revolving body whose first end diameter is larger than the second end diameter, and the second end of the abutment main body is provided with a round platform for connecting with an implant. From the first end to the second end of the main body of the abutment, the diameter of the round table gradually becomes smaller, and the implant is provided with a mounting hole for the round table to extend into. The mounting hole is a tapered hole and its taper is the same as that of the round table. The installation holes are connected by taper self-locking. The end surface of the first end of the main body of the abutment is provided with the same installation hole, and the bottom of the installation hole on the main body of the abutment is provided with a spanner hole with a polygonal cross section for a wrench to enter. With such a setting, when the healing abutment is removed, it is not necessary to reversely knock, but only to turn the wrench, which can effectively reduce the patient's discomfort and avoid causing injury to the patient. However, it is not necessary to remove the healing abutment when taking the impression, which can avoid damage to the patient caused by taking and wearing the healing abutment.

Description

technical field [0001] The invention relates to the technical field of oral implantation, in particular to a healing abutment and a wrench thereof. Background technique [0002] Dental implants, also called artificial dental implants, are a restoration method that implants biomaterials (commonly called implants) that are highly compatible with human bone into the alveolar bone, and then makes dental restorations on the implants. The process mainly includes: 1. Alveolar bone drilling, implant implantation, waiting for bone tissue and implant fusion; 2. Install healing abutment, so that the implant can be connected with the external structure, and waiting for soft tissue formation; 3. Soft tissue formation Finally, replace the healing abutment with a permanent abutment; 4. Wear a dental restoration. [0003] Before replacing the healing abutment with the permanent abutment, it is necessary to take an impression to determine the size of the permanent abutment. This process req...

AI Technical Summary

Problems solved by technology

[0005] If the clinical operation takes a long time after the healing abutment is removed, the gingival cuff will shrink significantly, which may cause pain for the patient when the healing abutment is reinstalled; and the repeated removal and wearing of the healing abutment will easily damage the existing abutment- The cuff epithelium binds the barrier, even increasing the risk of infection in patients with soft tissue injuries

Therefore, how to solve the above-mentioned clinical problems that are easily caused when the healing abutment is removed in the prior art, and how to reduce the need to remove the healing abutment when taking impressions is an urgent need for those skilled in the art to solve
