High-precision rapid manufacturing method for removable partial denture

Abstract

The invention relates to a High-precision rapid manufacturing method for a removable partial denture. The method comprises the following steps: 1) three-dimensional scanning is carried out on a modelrequiring removable partial denture restoration; 2) designing that removable partial denture with the CAD software of the removable partial denture; 3) designing and 3D printing a dental preparation guide plate based on the designed removable partial denture; 4) guiding by that tooth preparation guide plate to carry out tooth preparation on the model; 5) re-three-dimensional scanning and designinga new removable partial denture for the model of the tooth body prepared; 6) that removable partial denture newly design in the step 5) is manufactured so as to be able to be submit to clinical use together with the dental preparation guide plate. The invention is helpful to reduce the guiding error of the dental preparation guide plate of the removable partial denture, and can simultaneously complete the dental preparation and the denture wearing in the clinic; and the restoration precision and the efficiency of the removable partial denture are remarkably improved.

Description

technical field [0001] The invention relates to a manufacturing method of removable partial dentures, in particular to a high-precision and rapid manufacturing method of removable partial dentures. Background technique [0002] In the digital design of the removable partial denture in the prior art, for the use of the tooth preparation guide plate of the removable partial denture, it is easy to produce the guide error of the tooth preparation guide plate of the removable partial denture, and the tooth preparation and the denture wearing cannot be completed simultaneously clinically. As a result, the accuracy and efficiency of removable partial denture restorations are limited. Contents of the invention [0003] The purpose of the present invention is to provide a high-precision and rapid manufacturing method for removable partial dentures, which helps to reduce the guide error of the tooth preparation guide plate of the removable partial dentures, and can simultaneously co...
