Repairing, designing and manufacturing method of removable partial dentures

Abstract

The invention relates to a repairing, designing and manufacturing method of removable partial dentures. The repairing, designing and manufacturing method comprises the following steps that (1) dentition and gingiva which need to be subjected to removable partial denture repairing are subjected to three-dimensional scanning, and data D are recorded; (2) a support, a retainer, a connector, a base bracket and artificial teeth are designed by using CAD software; (3) a press-in type ball head spring plunger is designed in a denture guide flat panel area, and serves as a retaining device to replacevarious types of denture clamping rings; (4) gap cards are designed between teeth which are prone to being subjected to food impaction; (5) data fusion is conducted on all the designed structures andthe data D, and three-dimensional design of the repaired removable partial dentures is completed; and (6) a 3D printer is used for printing rear-row teeth, gluing is conducted, and manufacturing can be completed. According to the repairing, designing and manufacturing method of the removable partial dentures, the aesthetic effect of the removable partial dentures can be significantly improved, thenonphysiological lateral force on abutment is lowered, the long-term success rate of removable partial dentures repairing can be increased, and the repairing effect of removable partial dentures repairing can be improved.

Description

technical field [0001] The invention relates to a removable partial denture repair, in particular to a repair design and manufacturing method of a removable partial denture. Background technique [0002] When a patient is partially missing a tooth, it can be replaced with a removable partial denture. The classic design method of removable partial dentures relies on techniques such as manual carving and wax casting, which has large errors. And in order to be suitable for the low-precision design and manufacturing process by hand, its structure has not achieved the ideal effect of remaining tissue health care, functional reconstruction and aesthetic restoration. Metal 3D printing technology has been applied to the rapid and high-precision manufacturing of removable partial dentures, which can increase the manufacturing accuracy to 50-100 microns, which provides a basis for the design of new removable partial dentures that are more in line with physiological functions, aesthet...
