Abstract

Background

Mandibular kinematics is essential for assessing orofacial functions and understanding dysfunctions related to different types of malocclusion. Recording real-time mandibular dynamics aids in understanding kinematics, essential for treatment planning and outcomes.

Objective

To analyze mandibular kinematics within an orthodontic population employing the Modjaw optical tracking system.

Methods

A total of one hundred fifty-four patients participated in this observational study. Initial orthodontic records were analyzed. Mandibular kinematics was recorded using Modjaw^Ⓡ. Skeletal and dental parameters were determined by cephalometric analysis (ANB angle for skeletal classification).

Results

Significant variations in mandibular kinematics were detected across skeletal classes. The findings indicate that maxillomandibular relationships have a direct influence on mandibular movement and orthodontic treatment planning.

Conclusion

Individuals classified as Class III demonstrated significantly lower values in multiple key parameters, indicating that skeletal classification is crucial in influencing mandibular kinematic characteristics.

使用光学下颌跟踪技术对正畸人群下颌运动学的比较研究

背景：下颌运动学对于评估口面部功能和了解与不同类型错牙合相关的功能障碍至关重要。实时记录下颌骨动力学有助于了解运动学，对治疗计划和结果至关重要。目的应用Modjaw光学跟踪系统分析正畸人群的下颌运动学。方法共154例患者参与观察性研究。对最初的正畸记录进行分析。使用ModjawⓇ记录下颌运动学。骨骼和牙齿参数由头颅测量分析确定（ANB角用于骨骼分类）。结果在不同的骨骼类别中发现了下颌运动学的显著变化。结果表明，上颌下颌关系直接影响下颌运动和正畸治疗计划。结论分类为III类的个体在多个关键参数上的值明显较低，说明骨骼分类对下颌运动特征的影响至关重要。
