Problems solved by technology

[0002] Although the existing digital design of intraoral restorations 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 accuracy The design effect is not high, and the design effect is excessively dependent on the operator's experience and operating skills, and sometimes it needs to be redesigned to complete the design task; third, it takes a long time to accumulate expert experience, and junior technicians need to memorize a large number of cases to design qualified products

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0035] A digital design method for intraoral restorations based on big data, specifically comprising the following steps:

[0036] Step (1), three-dimensional scanning to obtain the dental model entity data M (corresponding to figure 1 1) in , and perform feature annotation on the entity data M of the dental model to obtain the characteristic data P of the dental model (corresponding to figure 1 2) in the above; scan to obtain the characteristic data D of the intraoral restoration (corresponding to figure 2 In 3), the three as a whole are regarded as a sample S, and multiple samples obtained by scanning form a removable partial denture (RPD) standard template database L, and the number of samples in the standard template database L covers various common dentures. Types...

Abstract

The present invention provides a digital design method for intraoral restorations based on big data, which belongs to the field of oral restoration and restorative technology, and defines the distance function of dental and jaw feature data to obtain the dental and jaw model feature data closest to the current dental and jaw feature data P1 P2, then use the dental model entity data M2 of the sample where P2 and P2 are located, the current dental model data M1, and the current dental and jaw feature data P1 as the input of the non-rigid point matching algorithm to obtain the transformation function T21; finally, the transformation function T21 is used On D2, use the self-adaptive surface fitting algorithm to obtain the design scheme D1 for reference by the prosthetic technician. The invention greatly reduces excessive manual interactive design operations in the prior art, and rapidly improves the design level, design efficiency and design accuracy of operators.

Description

technical field [0001] The invention belongs to the field of oral restoration and restoration technology, and in particular relates to a digital design method for intraoral restorations based on big data. Background technique [0002] Although the existing digital design of intraoral restorations 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 accuracy The design effect is not high, and the design effect is excessively dependent on the operator's experience and operating skills, and sometimes it needs to be redesigned to complete the design task; third, it takes a long time to accumulate expert experience, and junior technicians need to memorize a large number of cases to design qualified products. Contents of the invention [0003] In view of the deficiencies in the prior art, the prese...
