Abstract

The invention discloses a CAD/CAM digital manufacturing method for bracket movable denture. The method comprises the follow steps: 1) preparing data: scanning a tooth working model to obtain A data required for CAD design; 2) CAD design: CAD design bracket structure B, Form the A+ data needed to design the teeth and the base, CAD design the tooth structure C and the base shape, form the A++ data needed to design the base formwork, CAD design the base formwork structure D; 3) CAM production: extraction bracket Structure B, tooth structure C, base mold shell structure D three kinds of data for CAM typesetting, CAM cutting and then lost wax casting to obtain the support structure B, CAM cutting to obtain the tooth structure C, 3D printing to obtain the base mold shell structure D; Injection molding; 5) Grinding and polishing: The stent-type movable denture of the invention has simple preparation, high precision and short production cycle, reduces production cost and improves the quality of the movable denture restoration.

Description

technical field [0001] The invention relates to the technical field of bracket-type removable dentures, in particular to a CAD / CAM digital manufacturing method for bracket-type removable dentures. Background technique [0002] Removable dentures are removable dentures for missing or missing teeth. Those who repair missing dentition refer to complete dentures, and those who repair missing dentition refer to removable partial dentures. [0003] At present, CAD / CAM digital denture manufacturing technology is widely used in the field of oral fixed dentures and implant dentures due to its exquisite design, precise manufacturing and comfortable use. However, due to the lack of dentition and many types of dentition defects, the structure of the removable denture is complex. The removable denture usually includes three components: brackets, teeth or dentures, and bases, and the three components are composed of three different types of materials. Complete with single equipment and ...
