Tooth orthodontic treatment monitoring method based on intraoral image and three-dimensional model

Abstract

The invention discloses a tooth orthodontic treatment monitoring method based on an intraoral image and a three-dimensional model. The tooth orthodontic treatment monitoring method comprises the following steps that step 1, a preprocessed intraoral image and a dental jaw three-dimensional digital model of a patient at a P1 stage are obtained; step 2, tooth-gingiva and tooth-tooth segmentation is performed on the dental jaw three-dimensional digital model based on the intraoral image of the patient in the P1 stage, a segmented dental jaw three-dimensional digital model is obtained; step 3, a preprocessed intraoral image of the patient in a P2 stage is obtained; and step 4, the segmented dental jaw three-dimensional digital model is converted according to the intraoral image of the patient in the P2 stage, and a dental jaw three-dimensional digital model of the P2 stage and coordinate transformation data and morphological change data of the dental jaw models from the P1 stage to the P2 stage are generated. According to the tooth orthodontic treatment monitoring method based on the intraoral image and the three-dimensional model, coordinate transformation and form change conditions ofteeth of the patient after tooth orthodontic treatment can be known only by shooting the intraoral image, so that a scanner is prevented from being used for scanning an oral cavity after treatment.

Description

Technical field [0001] The invention belongs to the technical field of tooth monitoring, and in particular relates to a method for monitoring orthodontic treatment of teeth based on intraoral images and three-dimensional models. Background technique [0002] In the field of orthodontic treatment, dental monitoring (Dental Monitoring) technology allows orthodontists to monitor the patient's treatment status more conveniently, quickly and effectively. With the help of devices such as smartphones, doctors can remotely monitor the status of dental treatment without even requiring patients to go to a hospital or clinic. It not only saves the patient's time and money for multiple trips to the hospital or clinic to wait for treatment, but also greatly facilitates the doctor's tracking and monitoring of the patient's treatment process, and also helps the timely advancement, adjustment and improvement of the treatment plan. [0003] With the development of computer technology, the acquisit...

Problems solved by technology

[0004] At present, the acquisition of the 3D digital model still relies more on the data collection of the scanner, but during the scanning process, it is necessary to use the cheek retractor to open and fix the patient's mouth. It is not advisable to perform multiple scanner scans on patients during orthodontic treatment monitoring
