Embodiment 1

[0032] The orthodontic bracket bonding method disclosed in this embodiment using mixed reality technology has the following steps:

[0033] 1. Collect data and establish a digital dental model.

[0034] 1.1. Use an intraoral scanner to scan the patient's mouth, use software (such as 3Shape TRIOS, Copenhagen, Denmark) for pre-processing, automatically remove noise, fill cavities, fit and match the upper and lower jaw occlusal points, and convert it into the ratio of the real dentition in the patient's mouth 1:1 3D digital dental model with occlusal relationship;

[0035] 1.2. The patient received imaging examinations before treatment, taking cone-beam CT of the entire dentition, and obtaining imaging data of the patient's oral tissue and three-dimensional tooth roots;

[0036] 1.3. Use computer technology to import the data obtained by cone beam CT scanning into the patient in DICOM standard format. The three-dimensional digital dental model obtained in step 1.1 is integrated....

Embodiment 2

[0064] The orthodontic bracket bonding method disclosed in this embodiment using mixed reality technology has the following steps:

[0065] 1. Collect data and establish a digital dental model.

[0066] 1.1 Identification map placement:

[0067] 1.11, use silicone rubber to make the patient's ideal jaw occlusal relationship occlusal plate, and the occlusal plate leaves enough space for the bracket bonding;

[0068] 1.12, fixedly connect the identification map markers on the occlusal plate, and the identification map markers can be recognized by MR software;

[0069] 1.13. Use an intraoral scanner to perform a regular dentition scan, and collect the bite plate information with the markers of the identification map together, and use it for registration of the identification map in step 4;

[0070] Scan the patient's mouth, use software (such as 3Shape TRIOS, Copenhagen, Denmark) for pre-processing, automatically remove noise, fill the cavity, fit and match the occlusal points ...

Abstract

The invention relates to an orthodontic bracket bonding method using a mixed reality technology. The method comprises the following steps: S1, collecting data, and establishing a three-dimensional digital dental model with complete arrangement relation of dental crowns and tooth roots and occlusion information; S2, carrying out virtual bracket bonding on the three-dimensional digital dental model established in the S1, and outputting a three-dimensional digital dental model with a virtual bonding bracket; S3, importing the three-dimensional digital dental model with the virtual bonding bracket into a mixed reality head-mounted display; S4, registering the three-dimensional virtual image of the three-dimensional digital dental model with the intraoral reality by using software and optical tracking equipment and using a tracking registration technology; and S5, positioning the position of a real bracket according to the virtual bonding bracket, and completing bracket bonding. According to the invention, the real bracket bonding is guided by using the bracket virtual image through the mixed reality technology, so that the positioning scheme has both accuracy and convenience.

Description

technical field [0001] The invention relates to the field of orthodontic technology, in particular to an orthodontic bracket bonding method using mixed reality technology. Background technique [0002] For fixed orthodontic treatment technology, bracket bonding is one of the most important clinical steps, and its accuracy directly affects the treatment efficiency and final effect. [0003] At present, bracket positioning methods include clinical crown center method, height method, marginal ridge method, etc. The current orthodontic bonding technology is mainly divided into direct bonding technology and indirect bonding technology. The former is the most commonly used. The doctor directly locates and pastes the brackets in the mouth by visual inspection or using a bracket locator or a positioning table, but the field of vision is limited and the accuracy is limited, etc.; while the latter is used to position the brackets on a digital or plaster model. Then transfer the brac...
