Alveolar bone contour prediction model generation method and device, and a prediction method and devic

Abstract

The invention provides an alveolar bone contour prediction model generation method and device, and a prediction method and device. The alveolar bone contour prediction model generation method comprises the following steps: acquiring training sample data, wherein the training sample data comprises a feature image before correction, correction parameters and deformation quantities of upper and lower alveolar cavity contour lines after correction based on the correction parameters; taking correction parameters, a control point of an upper alveolar lingual side contour line before correction, a control point of an upper alveolar labial side contour line before correction, a control point of a lower alveolar lingual side contour line before correction, a control point of a lower alveolar labial side contour line before correction, a contour of upper incisors before correction and a contour of lower incisors before correction as input of an initial network model; performing supervised training by taking the corrected deformation quantity of the upper and lower alveolar contour lines as the output of the initial network model to obtain an alveolar bone contour prediction model. The alveolar bone after orthodontics can be scientifically and reasonably predicted through the obtained alveolar bone contour prediction model.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a method for generating an alveolar bone contour prediction model, a prediction method and a device. Background technique [0002] The range of orthodontic tooth movement should be limited to the alveolar bone. Tooth movement beyond the alveolar bone can cause bone fenestration and bone cracking, especially in the anterior region, as a side effect of orthodontics. However, the inventors have found in actual research that the shape of the alveolar bone is not static, and it will remodel along with the movement of the teeth. The mode by which the alveolar bone moves with the tooth is unknown. A scientifically sound method for predicting alveolar bone morphology after orthodontics is currently lacking. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a method for generating an alveolar bone contour pr...
