Embodiment Construction

[0014] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0015] A high-efficiency digital design method of a removable partial denture of the present invention has the following steps:

[0016] 1) Carry out three-dimensional scanning for the manually designed removable partial denture and its repaired dental model entity, and store it as a standard template data as a whole;

[0017] 2) Three-dimensional scanning of the current jaw model that needs to be repaired with a removable partial denture, which is recorded as data D1;

[0018] 3) Select a set of standard template data from step 1), and record it as data D2;

[0019] 4) Using the part of the non-missing teeth as the common area, use the common area registration algorithm to register the data D2 with the data D1;

[0020] 5) Delete the jaw model data in data D2;

[0021] 6) On the basis of step 5), the standard template data of the r...

Abstract

The invention relates to a high efficiency digital design method of removable partial denture. The method comprises the following steps: 1) three-dimensional scanning is carried out for the removablepartial denture designed and manufactured by hand and the dental model entity restored by the removable partial denture and the removable partial denture, and the whole storage is used as standard template data; 2) The current dental model which needs to be repaired with removable partial denture by three-dimensional scanning is denoted as data D1; 3) selecting a set of standard template data fromthat step 1) and recording as data D2; 4) take that non-missing tooth part as a common area, and registering the data D2 with the data D1 by a common area registration algorithm; 5) deleting the dental model data in the data D2; 6) on that basic of step 5), the standard template data of the removable partial denture is fine-tuned to meet the individualized requirement of the current dental jaw model, and the design is completed. The method greatly reduces excessive manual interactive design operation in the digital design software, improves the design level and efficiency of the operator, andimproves the design precision.

Description

technical field [0001] The invention relates to a digital design of removable partial dentures, in particular to a high-efficiency digital design method of removable partial dentures. Background technique [0002] Although the existing digital design of removable partial dentures can meet the requirements of digital design; however, due to too many manual interactive design operations in the design software, first, the design efficiency is low; second, too many manual interactive design operations lead to design The accuracy is not high, and the design effect depends too much on the operator's experience and operation skills, and sometimes it needs to be redesigned to complete the design task. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency digital design method for removable partial dentures, which can be directly used in the digital design and 3D printing of removable partial dentures, and greatly reduce the excessi...
