Cross-sectional 

研究目的:

应用T-scan咬合分析系统测量对比和分析正常覆𬌗和深覆𬌗青年学生在最大牙尖交错位的首次接触发生的区域、前后牙区咬合力占比、𬌗力不对称指数、咬合接触时间、咬合力占最大咬合力的占比、咬合接触面积以及在前伸颌位的咬合分离时间。  

Objectives of Study:

Using T-scan occlusal analysis system to measure, compare and analyze the area where the first contact occurred between normal overbite and deep overbite young students at the maximum cusp staggered position, the ratio of occlusal force between anterior and posterior teeth, the force asymmetry index, occlusal contact time, the ratio of occlusal force to the maximum occlusal force, the occlusal contact area and the occlusal separation time in the protrusive jaw position.
