Embodiment Construction

[0041] combine Figure 1 The method of automatic fusion of mouth sweep tooth data and CBCT data of the present embodiment comprises the following steps:

[0042] S1: Load the port sweep mesh data (mesh1), such as Figure 2 As shown; in the present embodiment, the mouth sweep mesh data is an object composed of a plurality of triangular patches;

[0043]S2: According to the mouth sweep mesh data loaded in step S1 for tooth segmentation; in the present embodiment, the use of AI intelligent segmentation, such as MeshSegNet network or other mesh segmentation framework; or conventional mesh segmentation method, manually edit the cutting contour on the mouth sweep overall mesh model to implement the segmentation of teeth.

[0044] S3: Loading CBCT data; in the present embodiment, the CBCT data comprises a series of two-dimensional slice data in dicom format.

[0045] S4: the CBCT data loaded in step S3 for AI segmentation; conventional AI medical image segmentation framework is used in the...

Abstract

The invention relates to a method for automatically fusing oral scanning tooth data and CBCT data. The method comprises the following steps: S1, loading oral scanning grid data; s2, dividing the mouth scanning grid data; s3, loading the CBCT data; s4, CBCT data AI segmentation is carried out; s5, carrying out gridding generation on a CBCT data segmentation result; s6, registration of oral scanning dental crown data and CBCT gridding data is carried out; s7, coordinate position information of the registered CBCT upper teeth and the registered CBCT lower teeth is calculated, and new CBCT upper tooth and lower tooth grid data are generated; s8, matching the upper tooth crown with an association point set; s9, matching a lower tooth crown with an association point set; s10, carrying out CBCT grid data deformation; and S11, reconstruction optimization of the CBCT grid data is carried out. According to the automatic fusion method based on the oral scanning tooth data and the CBCT data, the advantages of high dental crown precision of the oral scanning data and complete tooth root form of the CBCT data can be integrated, the appearance form after the oral scanning dental crown and the CBCT teeth are integrally fused is obtained, clinical doctors can be well guided to carry out work, and the tooth treatment precision is improved.

Description

Technical field [0001] The present invention relates to the oral medical field, in particular to a method of automatic fusion of mouth sweep tooth data and CBCT data and application thereof. Background [0002] With the improvement of people's living standards, the pursuit of the quality of oral medical services is becoming more and more common, and digital diagnosis and treatment equipment is widely used in clinical practice. At present, CBCT (Cone-beam computed tomography) and oral scanners (referred to as mouth scans) are commonly used in oral clinics to facilitate doctors to obtain patients' tooth arrangement and specific structural information. However, there are shortcomings such as the accuracy of the crown obtained by CBCT is not high, and the root of the tooth is missing from the mouth sweep data. Therefore, it is particularly necessary to study a method based on the automatic fusion of mouth scan teeth data and CBCT data. Contents of the Invention [0003] The technica...
