Pure titanium steel bracket based on 3D printing digital model

Abstract

The purpose of this application is to provide a pure titanium steel bracket based on the 3D printing digital model, which includes a base, a retainer, a bonding part and a snap ring. The retainer and the bonding part are arranged on the base, and the snap ring is connected to the Between the retainer and the bonding part, there are at least four retainers arranged continuously, and connecting pieces are fixedly connected between the several retaining bodies and the bonding part, and the upward part of the connecting piece is in a spiral shape. It solves the problem that when the number of teeth to be repaired is large and the positions are adjacent, the connection between the retainer of the pure titanium steel bracket and the oral cavity is poor, which affects chewing. The application has a reinforced pure titanium steel bracket retainer The effect of the connection strength with the bonding part makes the connection between the retainer and the bonding part more tightly, which is beneficial to the patient's chewing, and also increases the overall compressive strength and deformation resistance of the connecting part, making the pure titanium steel bracket The overall strength is further strengthened, the tensile strength is better, and it is more durable.

Description

technical field [0001] This application relates to the field of dental technology, in particular to a pure titanium steel bracket based on a 3D printed digital model. Background technique [0002] The steel bracket uses the remaining natural teeth, the mucosa and bone tissue under the base as a support, relies on retainers and clasps to fix the position of the denture, uses artificial teeth to restore the shape and function of missing teeth, and uses base materials to restore the defect. The alveolar ridge, jawbone and the surrounding soft tissue morphology is a prosthesis that patients can remove and wear by themselves. [0003] Pure titanium has the advantages of high strength, low density, high hardness, high melting point, strong corrosion resistance, and good plasticity. Pure titanium has no sensitization, carcinogenicity, distortion and other phenomena after contact with the human body, and can combine well with bone tissue, epithelium, connective tissue, etc., and ha...

AI Technical Summary

Problems solved by technology

[0004] When the number of teeth to be repaired is large and the positions are adjacent, the number of retainers should be increased accordingly and arranged continuously, so that the retainers are only fixed by the snap rings and bonding parts at both ends, and the patient can easily make the pure teeth when chewing. The titanium steel bracket becomes loose, which affects chewing

[0005] In view of the above-mentioned related technologies, the applicant believes that when the number of teeth to be repaired is large and the positions are adjacent, the connection relationship between the retainer and the bonding part of the pure titanium steel bracket is poor, which affects chewing.
