Embodiment Construction

[0013] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0014] A kind of high-precision fast manufacturing method of removable partial denture of the present invention has the following steps:

[0015] 1) Three-dimensional scanning of the model that needs removable partial denture restoration;

[0016] 2) Design removable partial dentures with removable partial denture CAD software;

[0017] 3) Design and 3D print tooth preparation guides based on the designed removable partial denture;

[0018] 4) Use the tooth preparation guide plate to guide the tooth preparation on the model;

[0019] 5) For the prepared model of the tooth, scan again in 3D and design a new removable partial denture;

[0020] 6) Manufacture the newly designed removable partial denture in step 5), which can be handed over to clinical use together with the tooth preparation guide.

[0021] As described above, the pres...

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...
