Abstract

The invention discloses an automatic orthodontic difficulty coefficient evaluation method, comprising: obtaining a tooth model of the oral cavity to be evaluated, and optimizing the data of the tooth model to generate first tooth data; extracting details from the first tooth data The data features of the granularity are used as the second tooth data; the second tooth data is segmented and smoothed to form the third tooth data; a plurality of orthodontic difficulty evaluation parameters are generated according to the third tooth data to evaluate the orthodontic difficulty. The automatic orthodontic difficulty coefficient evaluation method of the present invention fully digitally and automatically processes the orthodontic difficulty coefficient evaluation, effectively improves the accuracy of the orthodontic difficulty evaluation, does not rely on the experience judgment of doctors, and is conducive to large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of computer application technology and computer vision, in particular to an automatic orthodontic difficulty coefficient evaluation method. Background technique [0002] Malocclusion is one of the most common oral diseases in modern humans. In malocclusion, objective and quantitative assessment of the difficulty of individual orthodontic treatment is the cornerstone of clinical diagnosis and treatment. The promotion of orthodontic difficulty assessment is conducive to the planning and decision-making of hierarchical diagnosis and treatment, optimizes the utilization of medical resources, and can provide guidance for clinical audit activities. [0003] At present, the commonly used orthodontic difficulty assessment indices in the world include the Discrepancy Index (DI), the peer assessment grade index, and the treatment complexity index. The DI is a reliable index developed by the American Board of Orthodontics to a...
