髁突轨迹描记曲线系统分析

摘要

通过分析运动面弓记录的髁突运动模式来判断颞下颌关节内各结构的形态位置关系、肌肉功能状态和下颌运动功能障碍,结合其他临床检测手段(临床和影像学检查等),对口颌系统的生理或病理状态作出诊断.目前国内尚缺乏对髁突轨迹描记曲线的系统分析方法,本文通过文献复习,结合笔者在临床多年的使用经验,从静态和动态两方面对髁突轨迹描记曲线的临床意义进行分析,以期为颞下颌关节疾病的诊断提供帮助.%With the kinematic face bow, the condyle movements representing temporomandibular joint function can be recorded instantly. The condylography curves can be utilized for diagnostic analysis, as different pathophysiological conditions have unique curve patterns. By tracing the specific alterations on the curves, the structural and functional statuses of the tem-poromandibular joint can be predicted. However, to the best of our knowledge, no standardized and practicable evaluation protocol for jaw movement tracing exists. In the current study, the features of either normal or abnormal curves were reviewed. Such features can be clinically used for determining temporomandibular joint status, thereby contributing to a comprehensive diagnosis.
