Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment:

[0020] The invention discloses a tooth model matching method, which includes: acquiring a tooth model matching method for orthodontics in the early stage, including: importing a virtual expected tooth digital model; acquiring a tooth data and generating A virtual tooth digital model; perform preliminary matching, place the tooth digital model and the expected tooth digital model in the same coordinate system; accurately match the tooth digital model and the expected tooth digital model; obtain the expected tooth digital model and the tooth digital model after matching Bias value for model data.

[0021] Further, acquiring tooth data includes: scanning the patient's oral cavity to acquire tooth data in the oral cavity.

[0022] Further, obtaining a tooth data may also include: obtaining by scanning the positive model of the tooth with a 3D scanner.

[0023] Further, the preliminary ...

Abstract

The invention discloses a method for matching teeth with a model. The method comprises the following steps: introducing a virtual expected digital tooth model; obtaining a tooth data and generating a virtual digital tooth model; preliminarily matching and placing the digital tooth model together with the expected digital tooth model into a same coordinate system; adopting a three-dimensional matching algorithm for accurately matching the digital tooth model with the expected digital tooth model; obtaining a deviation value after the digital tooth model is matched with the expected digital tooth model. The invention provides a condition for quantitatively adjusting an orthodontic scheme on the basis of an orthodontic effect; the quality control problem is solved; a quantitative effect evaluation scheme is also supplied for the traditional orthodontics.

Description

technical field [0001] The invention relates to a model matching method, in particular to a tooth model matching method applied to orthodontics. Background technique [0002] Orthodontics is the correction of teeth and the removal of malocclusion. Orthodontics mainly studies the etiology, diagnosis, analysis, prevention and treatment of malocclusion. [0003] Orthodontic treatment usually takes six months to two years to complete, with individual complex cases taking longer to complete. Based on different orthodontic treatment techniques, patients need to go to the clinic for follow-up visits at regular intervals to check the treatment effect and make certain adjustments based on medical technology. [0004] For traditional orthodontic technology, doctors usually judge the orthodontic effect by visual judgment. There are many subjective factors, and the judgment results of different doctors have large deviations. [0005] Now there are more orthodontic technologies based ...
