[0002] at present The use of stents is mainly in prosthodontics. The standard procedure is to first take an intraoral impression, which is not fully adjustable. The mechanical facebow was used to record the position of the maxilla relative to the skull and the dental arch in the patient's static state, recording the patient's occlusion. The occlusion was then transferred from the patient's mouth to a transfer table. On the shelf, through The frame simulates the opening and closing movements of the human jaw; if an electronic face bow is used, the patient's occlusal relationship is transferred to CAD software, where it is visualized electronically. The occlusal relationship of the simulated patient was analyzed and adjusted, and the complex movements of the patient's mandible were recorded.

[0003] The frame is designed to simulate the structure of various parts of the human maxillofacial region, including the body of the upper and lower jawbones, the lateral columns of the mandibular ramus, the condylar ball and condylar groove of the condyle and glenoid fossa, and the incisor guide, incisor guide inclination, condylar guide and condylar guide inclination to simulate the movement of the human mandible. All components are connected by metal joints to realistically reproduce the human bite relationship and mandibular movement as much as possible.
