Digital design method of removable partial denture rest

Abstract

The invention belongs to the field of oral cavity repair and repair technologies, and relates to a digital design method of a removable partial denture rest. The method comprises the following steps:firstly, drawing design lines of component parts of the rest by using a pencil on a solid model according to requirements of a doctor and design theory knowledge of removable partial dentures; and then, performing three-dimensional scanning by using a scanner to obtain a three-dimensional digital model with the rest design lines, and carrying out digital design according to the scanned rest designlines. The modification of the digital design can be greatly reduced, the influence on the operation rate of design software is reduced, the whole flow is highly pipelined, the training difficulty ofoperators is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of oral restoration and restoration technology, and relates to a digital design method for removable partial denture brackets. Background technique [0002] Metal bracket removable partial dentures have become the main choice of removable partial dentures due to their advantages of high strength, heat conduction, and relatively small size, and are widely used in the field of oral dentition defect repair. The metal bracket is the main structure of the metal bracket type removable partial denture. It is composed of retainers, connectors, rests and metal dentures. Artificial teeth and plastic bases are attached to the metal bracket. The commonly used metal material is cobalt For chromium alloy and titanium metal, commonly used molding processes include casting molding and CAM molding (including 3D printing additive molding and cutting subtractive molding). [0003] With the maturity of CAM molding technology, its high a...

AI Technical Summary

Problems solved by technology

This kind of operation method has relatively high requirements for the designers, who need to have a high degree of design knowledge of removable partial dentures, and also be proficient in the operation of digital bracket design software. Difficulty in training

Moreover, in order to ensure that the type, shape, position, size, and boundary of each component of the bracket are in compliance with the norms, and that the edge line of the bracket is smooth and beautiful, it is often necessary to design the digital bracket directly on the 3D digital model. Multiple revisions, these repeated revisions themselves will waste a lot of time, and will increase the calculation amount of the design software, reduce the calculation speed of the design software, further waste operating time, and reduce production efficiency
