Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The mandibular movement trajectory recording and analysis system of the present invention includes a test marker rod and at least two infrared cameras, preferably an infrared camera with an infrared emitting device, and the infrared camera is connected with a computer host for analyzing camera recording data. The rear end of the test marker rod is fixed on the mandibular incisor of the tester. The front end of the test marker rod is connected with a marker that is exposed outside the mouth and moves with the mandible to reflect the movement track of the mandible. The infrared camera records the movement track of the marker at the front end of the test marker rod. The motion track data is sent to the host computer for analysis and processing to judge whether ...

Abstract

The invention discloses a mandible movement track recording method, including the following steps: a, the rear end of a test marking rod is fixed at the mandible incisor part of a tester, the front end of the test marking rod is connected with a marker exposing port and moves along with the mandible; b, the movement track of the marker at the front end of the test marking rod is recorded by virtue of at least two infrared cameras provided with an infrared launching device, and movement track data is transmitted to a computer host to be analyzed and processed; c, the movement track of the marker is reconstructed in the computer, so as to correspondingly reflect three-dimensional track of mandible movement of the tester, and the recorded mandible movement three-dimensional track and calculated relevant parameters are respectively compared with mandible standard movement track and standard parameters which are stored by the system, so as to judge whether mandible movement and occlusion of upper and lower dentitions are normal or not. Besides, the invention also discloses a mandible movement track recording system.

Description

technical field [0001] The invention relates to a medical detection device, in particular to a system and method for recording mandibular movement track. Background technique [0002] Human mandibular movement is a complex three-dimensional movement involving teeth, masticatory muscles and temporomandibular joints. Its movement pattern is closely related to the health of the oral and jaw system. The characteristics of mandibular movement can be used to analyze and understand chewing, swallowing and language. It can analyze and diagnose temporomandibular joint lesions and judge the curative effect, and can also be designed according to the law of mandibular movement. It is also necessary to design and manufacture the restoration according to the individual characteristics of the mandibular movement. [0003] The recording method of the mandibular movement trajectory was originally to explore the law of mandibular movement through autopsy. In 1921, B.McCollum developed a mec...
