Three-dimensional imaging and real-time modeling based oral rehabilitation method

Abstract

The invention discloses a three-dimensional imaging and real-time modeling based oral rehabilitation method. The method includes the following steps: step one, utilizing a scanning device to rapidly obtain a facial model and dental model of a patient in real time, wherein the facial model is the color three-dimensional point cloud data of the mandibular part of the face when the patient grins, andthe dental model is the color three-dimensional dental point cloud data of the upper and lower dentitions in the mouth of the patient under an occlusal state. Thus, the color three-dimensional facialmodel and color three-dimensional full mouth dental model of the patient can be rapidly obtained in real time, and intraoral scanning and real-time modeling can be directly performed, so that workingefficiency can be enhanced; the oral environment of the patient can be simulated by registering the dental model in the mouth of the patient; through the rehabilitation design of the three-dimensional model of doctors for the patient, the patient can visually observe the simulation effects before and after dental rehabilitation, so that good communication between the doctors and the patient can be achieved; and based on the three-dimensional oral rehabilitation design, various disadvantages of two-dimensional DSD can be overcome, and oral digital design can be completed.

Description

technical field [0001] The invention relates to the technical field of oral restoration, in particular to an oral restoration method based on three-dimensional imaging and real-time modeling. Background technique [0002] In recent years, oral health has attracted more and more attention, and people's demand for oral beauty is also increasing. Traditionally, an orthodontist takes an alginate impression of a patient's teeth and converts it into a stone model, using calipers to measure the tooth width, various studies have shown that calipers are accurate and reliable, they are easy to manufacture, cheap and accurate, and are considered is a tool for diagnosis and treatment planning, but it also has disadvantages such as storage costs and the possibility of breakage and wear. [0003] Digital smile design (DSD) is a virtual aesthetic restoration design tool commonly used by aesthetic dentists. DSD takes pictures of the patient’s frontal smile, resting jaw position, and front...

AI Technical Summary

Problems solved by technology

However, there is still a large gap between domestic research on oral aesthetic restoration and foreign countries. The measurement speed and accuracy need to be improved. There are no mature products and corresponding research for direct measurement of intraoral teeth. It is expensive to purchase the entire digital dental medical system abroad. The burden on physicians and patients is too heavy
