Study design:

Cross-sectional 

研究目的:

1. 通过CBCT测量不同类型错牙合畸形成年患者的髁突形态与位置特征,并进行4D描记髁突的功能性运动轨迹; 2. 解析错牙合畸形因素与髁突结构和功能运动的潜在关联及可能影响机制; 3. 尝试识别与错牙合畸形因素相关的髁突功能运动特征。  

Objectives of Study:

1. Measure the morphology and positional characteristics of the condyle in adult patients with different types of malocclusion using CBCT, and record the functional movement trajectory of the condyle in 4D; 2. Analyze the potential correlation and possible influencing mechanisms between malocclusion factors and condylar structure and functional movement; 3. Attempt to identify condylar functional and motor features associated with malocclusion factors.
