A method for detecting the state of orthodontic treatment during orthodontic treatment

Abstract

The invention belongs to the technical field of digital orthodontics in the field of digital medical treatment, and in particular relates to a method for detecting the state of orthodontic treatment of teeth in the course of orthodontic treatment. The invention utilizes the photographed teeth of the patient, and based on the computer two-dimensional image processing technology and the computer three-dimensional modeling technology, to detect the patient's tooth correction state at low cost. The invention makes it possible for the patient to detect the state of orthodontic treatment at home, without the need for the patient to go to the hospital for oral scanning or tooth bite, which greatly reduces the cost of the patient and the hospital. At the same time, the solution of the present invention directly uses the patient's tooth model before orthodontic treatment to detect the patient's orthodontic status, so the patient's previous digital orthodontic solution can be directly reused, greatly reducing the cost of orthodontics.

Description

technical field [0001] The invention belongs to the technical field of digital orthodontics in the field of digital medical treatment, and in particular relates to a method for detecting the state of orthodontic treatment of teeth in the course of orthodontic treatment. Background technique [0002] Orthodontics is the straightening of teeth, through orthodontic brackets, orthodontic braces, etc., to use external force to pull the teeth to align the teeth. Digital orthodontics is to apply computer-aided technology to orthodontic treatment, and carry out digital tooth data acquisition, storage, orthodontic plan design and other steps. [0003] During orthodontic treatment, patients often need to go to the hospital for follow-up visits to check the state of the orthodontic treatment. There are three main methods for detecting the state of orthodontic treatment: the first is that the patient goes to the hospital, and the doctor checks the patient’s teeth on the spot to detect ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above methods are: 1. If only the patient's teeth are photographed, only the two-dimensional information of the teeth can be obtained, but the three-dimensional information of the patient cannot be obtained, and the three-dimensional orthodontic status of the patient cannot be well quantified; 2. If Using a plaster occlusal model to take an impression requires the patient to go to the hospital for operation. For the hospital and the patient, the cost is relatively high; 3. Using a professional oral scanner to scan the oral model requires the patient to go to the hospital for operation. For hospitals and patients, the cost is relatively high; and to obtain the oral scan model, it is necessary to re-do steps such as crown segmentation and orthodontic scheme design, and the original digital orthodontic scheme cannot be directly used, which is time-consuming and laborious.

4. The doctor inspects the patient's teeth on the spot. The patient's orthodontic status inspection depends on the doctor's experience, which cannot be quantified and measured, and the inspection results cannot be digitized, and the original digital orthodontic design cannot be reused.
