Self-tapping dental implant

Abstract

The invention belongs to the technical field of dental implants, and in particular relates to a self-tapping dental implant, which includes a body, two ends of the body are respectively provided with a screw-in end and a coronal end for connecting a dental prosthesis, and the outer surface of the coronal end There is a double-start thread starting from the body and ending at the mouth edge of the crown end. The beneficial effects of the present invention are: the friction force formed by the screwing of the double-start thread and the crest is small, which facilitates the self-tapping of the dental implant; the damage to the bone of the crest is minimal during the insertion process, and the force is small and evenly distributed. Avoid local stress concentration; the area of ​​attachment increases, which can easily improve the osseointegration strength of the implant, and the stress level in the later stage is low; under the conditions of external load and constraints, the stress and strain of the cortical bone are reduced, and it is not easy to Local stress concentration is generated, and the teeth are very strong. The teeth are very strong; when screwed into the crest, the resistance is small, the self-tapping performance is good, and the amount of alveolar bone that can be accommodated is high, and the stability is high.

Description

technical field [0001] The invention belongs to the technical field of dental implants, in particular to a self-tapping dental implant. Background technique [0002] When teeth are extracted due to tooth decay, broken teeth, or periodontal disease, artificial dental implants are currently a common treatment for missing teeth. In the alveolar bone, through the close assembly of the artificial tooth root and the alveolar bone, the artificial tooth root is used as the base to install the dental model. [0003] Dental implant technology has gone through more than 30 years of development, from the early leaf-shaped structure and columnar structure to the current threaded structure. It should be noted that the stability and reliability of the implant have been effectively improved, but the initial stability of the implant is still not high enough. In particular, bone loss around early implants has always been a headache in the field of dentistry. The coronal (collar) area of ​​...

AI Technical Summary

Problems solved by technology

The coronal (collar) area of ​​traditional implants is often smooth on the surface or provided with several rings of circular grooves, which is not easy to penetrate at the top of the crest, and the continuous extrusion of the alveolar crest during the implant process will aggravate the bone loss of the alveolar crest. In addition, after the implant and bone tissue are well combined, the attachment area is small, and it is difficult to improve the osseointegration strength of the implant; under the conditions of external load and constraint, the stress and strain of the cortical bone increase , and prone to local stress concentration; it should also be pointed out that it can accommodate less alveolar bone and poor stability
