Embodiment 1

[0042] Example 1 Fixed orthodontic examination and evaluation

[0043] This embodiment provides an orthodontic examination and evaluation method using mixed reality technology, including the following steps

[0044] (1) Import preparatory data: import pre-obtained preparatory 3D model data;

[0045] (2) Construct a realistic scene: Paste the marker points to construct a scene suitable for measurement;

[0046] (3) Complete scene tasks: Wear a mixed reality device to complete the tasks in the corresponding scene;

[0047] (4) Obtain real scene data: obtain sensor data during use;

[0048] (5) Model establishment: The computer calculates the patient's real-time oral three-dimensional model data and simulates the tooth root data based on the sensor data;

[0049] (6) Result output: compare the prepared model data with the real-time model data, and the computer calculates the tooth space change data according to the model data;

[0050] (7) Evaluation of orthodontic treatment ef...

Embodiment 2

[0072] Example 2 Evaluation of facial appearance improvement after orthodontics

[0073] This embodiment provides an evaluation of the improvement of the patient's facial appearance after orthodontics using mixed reality technology, including the following steps:

[0074] (1) Import preliminary data: import pre-acquired facial appearance data of patients before treatment;

[0075] (2) Construct a realistic scene: paste markers on the patient's face;

[0076] (3) Complete scene tasks: wear a hybrid display device to complete tasks in the scene;

[0077] (4) Obtain real scene data: obtain sensor data during use;

[0078] (5) Model establishment: construct a three-dimensional coordinate system, and determine the relative three-dimensional positional relationship of each marker point;

[0079] (6) Result calculation: calculate the required data by computer;

[0080] (7) Result evaluation: compare with the preliminary data to judge the improvement of facial appearance.

Abstract

The invention provides an orthodontic treatment examination and evaluation method utilizing a mixed reality technology. The mixed reality scene provided by the invention can conveniently and effectively determine the tooth and face data of a patient, evaluate the correction effect and dynamically record the treatment process, so that inaccuracy caused by naked eye observation of doctors or picturecompression deformation caused by radiation examination in traditional examination is avoided, naked eye evaluation for the treatment effect is replaced with virtual and real comparison, quantified and accurate orthodontic examination and evaluation data can be obtained, and treatment records can be dynamically reviewed. The constructed mixed reality scene can effectively assist a user in completing orthodontic treatment examination and evaluation work, the completion degree is increased, and subjective errors are reduced; and meanwhile, compared with a traditional method, the visualization degree is high, the display continuity of the treatment condition is good, recording and doctor-patient communication are facilitated, the cost is relatively low, use is convenient, and very convenientconditions are provided for clinical use and popularization.

Description

technical field [0001] The invention relates to the medical field of mixed reality technology, in particular to an orthodontic examination and evaluation method using mixed reality technology. Background technique [0002] Orthodontics is a method of diagnosis and treatment for the incoordination of the relationship between teeth, jaw, cranium and face, as well as the abnormal relationship between the upper and lower dental arches and occlusal relationship. The purpose of treatment is to achieve the coordination of dentition, jaw, and facial shape by moving teeth and jaws, and to improve masticatory function and facial appearance. Clear aligners and fixed aligners are currently one of the most commonly used orthodontic appliances. During the orthodontic process using clear aligners, the patient wears clear aligners in order according to the treatment stage, gradually moving the teeth. Clinically, the dentition information is scanned by the oral scanner to form a three-dime...
