Personalized lower jawbone biomechanics model stress measurement system

Abstract

The present invention provides a personalized lower jawbone biomechanics model stress measurement system. The system comprises a measurement pedestal, a muscle strength equivalent structure, the fixing device of the muscle strength equivalent structure, an articular disc fixing device, a loading platform and a strain gage. The fixing device of the muscle strength equivalent structure, the articular disc fixing device and the loading platform are installed on the measurement pedestal, the personalized lower jawbone biomechanics model includes a lower jawbone and two temporal-mandibular joint discs, the lower jawbone is provided with the spring hanger of the upper jaw muscle group, the strain gage is pasted at the measurement region of the lower jawbone, the two temporal-mandibular joint discs are fixed in the articular disc fixing device, two condyles on the lower jawbone model are arranged in the articular disc, the teeth for bearing the bite force in the lower jawbone model is contacted with the motion end of the loading platform, the lower end of the muscle strength equivalent structure is connected with the spring hanger, and the upper end of the muscle strength equivalent structure is connected with the fixing device of the muscle strength equivalent structure. The personalized lower jawbone biomechanics model stress measurement system can express the patient's real condition and has good measurement accuracy.

Description

technical field [0001] The invention relates to a mandible biomechanical model measurement technology, in particular to a stress measurement system of a mandibular biomechanical model. Background technique [0002] The mandible is the largest in volume and area among the maxillofacial bones of the human body, and it is also the only movable facial bone. It is connected to the cranio-mandibular bone through the temporomandibular joint and the mandibular muscles. The biomechanical model of the mandible is the mechanical basis for the formulation of precise treatment plans for oral or dental diseases such as surgical repair of mandibular fractures, mandibular defect reconstruction, dental implant surgery, orthodontics, as well as maxillofacial collision simulation and trauma analysis. The difficulty in constructing a biomechanical model of the mandible lies in two aspects: one is the non-uniform material properties of the mandible, and the other is the application of mandibular...
