Modeling and evaluating method for tooth jaw movement track

Abstract

The invention provides a modeling and evaluation method for a tooth jaw movement track. The method comprises the following steps: acquiring structural information of a skull and a mandible of a patient in a CT scanning mode; acquiring tooth structure information of a patient through intraoral structure scanning; combining the structure information of the skull and the mandible and the tooth structure information through computer three-dimensional modeling to form a three-dimensional human body tooth jaw movement model; acquiring the tooth jaw movement track information of the patient through a tooth jaw movement track collecting face arch; driving the three-dimensional human body tooth jaw movement model based on the tooth jaw movement track information, extracting tooth jaw abnormal contact point information in the occlusion process, calculating the tooth collision degree in the three-dimensional human body tooth jaw movement model, and judging whether the teeth of the patient are in high-quality arrangement or not; evaluating the occlusion track of the patient according to the tooth jaw movement track information, and judging whether the tooth jaw movement track of the patient is a high-quality occlusion track or not. Therefore, the tooth jaw movement track of the patient can be reproduced by using a digital technical means.

Description

technical field [0001] The invention relates to the technical field of dental health medical detection, in particular to a modeling and evaluation method of a tooth and jaw motion trajectory. Background technique [0002] At present, with the continuous improvement of people's quality of life, more and more people begin to pay attention to oral and dental treatment, which leads to the rapid development of stomatology. Whether it is the eating and masticating organs of the human body or as the appearance of the face, the teeth and jaws are all in people's lives. has a very important position. After damage to the jaw, the existing widely used traditional facebow-adjustable jaw frame system to measure the movement trajectory of the patient's jaw has gradually exposed insurmountable limitations and cannot meet the needs of basic clinical treatment.

Problems solved by technology

After damage to the jaw, the existing widely used traditional facebow-adjustable jaw frame system to measure the movement trajectory of the patient's jaw has gradually exposed insurmountable limitations and cannot meet the needs of basic clinical treatment. The following problems exist:

[0003] 1. It is necessary to invert the patient's jaw, and use the demoulded patient's jaw model to measure the movement trajectory of the jaw, which requires a long period of time for model making;

[0004] 2. The operation is not intelligent enough, the measurement process is cumbersome and requires professional and technical personnel to perform measurement operations
