Processing technology for manufacturing implanted pure titanium bridge denture by combining additive and subtractive materials

Abstract

The invention relates to the field of complete implant dentures, and provides a processing technology for manufacturing an implant pure titanium bridge denture by combining additive and subtractive materials. The processing technology comprises the following steps that a transfer rod is clinically installed, a formal impression is taken, and a plaster model is poured; the shape of the bridge is evaluated by using the formal restoration, and back-cutting is carried out to manufacture a resin bridge; scanning and printing of the shape of the resin bridge are carried out by using a 3D scanning and printing technology; CAD software is used for scanning a resin bridge interface, designed data are output to CAM equipment, a pure titanium bridge interface is accurately cut, and a screw retentionhole is formed in a pure titanium bridge. According to the method, material waste is effectively reduced in a 3D scanning printing additive mode, the formed pure titanium bridge can be of a hollow structure, the weight of a finished product is effectively reduced, the material cost is reduced, meanwhile, bonding of external materials is facilitated due to the rough surface, a rough surface does not need to be manufactured on the pure titanium bridge, and then the manufacturing efficiency of the finished product is improved.

Description

technical field [0001] The present disclosure relates to the field of full-mouth implant dentures, in particular to a processing technique for implanting pure titanium bridge-frame dentures by combining addition and subtraction materials. Background technique [0002] For most elderly people who often have the problem of losing all the teeth in their mouths, hospitals usually adopt a full restoration method to make complete dentures to help patients restore their oral chewing function. [0003] For the existing production technology of planting pure titanium bridge dentures, the planting pure titanium bridge is usually processed by casting integral molding or the bridge is made by cutting technology. During the casting process of titanium, its interior is affected by thermal expansion and contraction, and has a certain stress, which leads to a certain deviation between the fabricated denture and the originally designed size. Although the cutting process can ensure the accur...

AI Technical Summary

Problems solved by technology

During the casting process of titanium, its interior is affected by thermal expansion and contraction, and has a certain stress, which leads to a certain deviation between the manufactured denture and the originally designed size.

Although the cutting process can ensure the accuracy of the bridge frame, this manufacturing method wastes a lot of material costs and the processing efficiency is low
