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. The self-tapping dental implant comprises a body, wherein a screw-in end anda crown end used for connecting with the dental implant are respectively arranged at two ends of the body; and a double-headed screw thread starting from the body and ending at an mouth edge of the crown end is arranged on an outer side face of the crown end. The self-tapping dental implant disclosed by the invention has the beneficial effects that friction force formed by screwing the double-headed screw thread and a ridge crest is weak, and the dental implant is conveniently self-tapped; destruction of bones on the ridge crest is the minimal in the implanting process, the stress is low, thedistribution is uniform, and local stress concentration is avoided; an area attachment area is enlarged, the bone bonding strength of the implant is easily improved, and the later stress level is low; under external load and constraint conditions, stress and strain stressed by cortical bones are decreased, local stress concentration is difficult to cause, and the teeth are very strong; and when being screwed into the ridge crest, the self-tapping dental implant is low in resistance, excellent in self-tapping property, capable of containing alveolar bones at a high quantity and high in stability.

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
