Defective tooth prediction method and device of oral cavity image

The present invention provides a defective tooth prediction method for an oral cavity image, which is a method for predicting defective teeth in an oral cavity image, and comprises the steps of: generating a standard tooth model by statistically learning a plurality of learning images; performing global matching on the oral cavity image and the standard tooth model; first and second adjacent teeth located on both sides of the defective tooth are compared, respectively, with first and second standard teeth of a standard tooth model corresponding to the first and second adjacent teeth, respectively, to predict the defective tooth. 本发明提供一种口腔图像的缺损牙齿预测方法，是在口腔图像中预测缺损牙齿的方法，包括如下步骤：通过统计地学习多个学习图像而生成标准牙齿模型；对口腔图像和标准牙齿模型进行全局匹配；将位于缺损牙齿的两侧的第一邻近牙齿和第二邻近牙齿与分别与第一邻近牙齿和第二邻近牙齿对应的标准牙齿模型的第一标准牙齿和第二标准牙齿分别进行比较，而预测缺损牙齿。
