A method of manufacturing a removable partial denture

Abstract

The invention relates to a manufacturing method of a removable partial denture, which comprises the following steps: 1) performing three-dimensional scanning on a model requiring removable partial denture restoration; 2) designing the removable partial denture with CAD software for removable partial denture; 3) based on Design and 3D print the tooth preparation guide plate for the designed removable partial denture; 4) use the tooth preparation guide plate to guide the tooth preparation on the model; 5) scan and design the tooth preparation model again New removable partial dentures; 6) The newly designed removable partial dentures in step 5) are manufactured, which can be handed over to clinical use together with the tooth preparation guide. The invention helps to reduce the guiding error of the teeth preparation guide plate of the removable partial denture, and can complete the tooth preparation and denture insertion clinically synchronously, and significantly improves the restoration accuracy and efficiency of the removable partial denture.

Description

technical field [0001] The invention relates to a manufacturing method of removable partial dentures, in particular to a 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 guiding error of the tooth preparation guide plate of the removable partial denture, and the tooth preparation and 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 method for making removable partial dentures, which helps to reduce the guide error of the tooth preparation guide plate of the removable partial dentures, and can simultaneously complete tooth preparation and denture insertion clinically; ...
