Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] refer to Figure 1 ~ Figure 3 , a method for identifying the degree of periodontitis resorption based on mesial and distal key points, comprising the following steps:

[0049] Step S1. Obtain dental panoramas, perform an image enhancement operation on each panorama, and combine the original panorama with the enhanced panorama to obtain an input I.

[0050] The present application performs necessary preprocessing on the acquired dental panoramas, the acquisition of dental panoramas, image enhancement operations on each panorama, and the combination of the initial panorama and the enhanced panorama, as model input I ,include:

[0051] Input the original tooth panorama, and perform image enhancement on the panorama. The enhancement methods include vertical flip, horizontal flip, affine transformation, and random rotation. After that, the original image and the en...

Abstract

A method for identifying the periodontitis absorption degree based on mesial and distal key points comprises the following steps: firstly, acquiring panoramic images of teeth, performing image enhancement operation on each panoramic image, and combining the initial panoramic image and the enhanced panoramic image together to serve as segmentation model input; inputting the panoramic film into a full tooth segmentation model to obtain a segmentation result, and cutting a single tooth area in the segmentation result to obtain a single tooth image; and then, inputting a single tooth image into the mesial and distal key point detection models to obtain a detection result; and finally, calculating the periodontitis absorption degree of the teeth according to the distance relationship between the key points in the detection result. According to the method, the regional information of each tooth can be extracted, so that interference information among the teeth in the panoramic film is greatly reduced, in addition, six point positions required for judging the periodontitis absorption degree can be identified from the single tooth image, and the identification accuracy is improved, so that the actual requirements of hospitals are met.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a method for identifying the degree of periodontitis absorption based on mesial and distal key points. Background technique [0002] Periodontal disease refers to the inflammatory lesions and destruction of periodontal supporting tissues (including gingiva, periodontal ligament, alveolar bone, cementum, etc.), and is a common and frequently-occurring disease that affects the oral health of residents. the main reason. [0003] The results of the fourth national oral health epidemiological survey show that more than 80% of middle-aged and elderly people in my country have gingival inflammation, and more than 40% have alveolar bone resorption and loss of periodontal attachment. According to this estimate, the number of patients with periodontal disease is huge, and the medical resources and economic costs consumed are inestimable. Periodontal disease often affects most of t...
