BACKGROUND
Mandibular deviations are common clinical complaints. The orthodontic or orthognathic treatment of mandibular deviations is tricky because a comprehensive diagnosis, especially a functional one, is difficult to make. A inaccurate diagnosis may lead to a compromised and unstable treatment outcome.
CASE PRESENTATION
This article describes the diagnosis and treatment of a woman with a mandibular deviation and facial skeletal asymmetry. By eliminating the disharmony of the arch form with elastics and bite turbos, her esthetic and functional outcomes improved. Cone-beam CT (CBCT) and Joint Space Index (JSI) analyses served as the diagnostic approaches and outcome evaluation methods before and after treatment.
CONCLUSIONS
A condyle position displacement could be an indication of functional deviation. JSI analysis is a quantitative and convenient choice to compare condyle relative positions.
背景
下颌偏斜是常见的临床主诉。下颌偏斜的正畸或正颌治疗颇具难度，因为全面的诊断，尤其是功能诊断，难以做出。不准确的诊断可能导致治疗结果不理想和不稳定。
病例报告
本文描述了一位女性下颌偏斜和面部骨骼不对称的诊断和治疗。通过用橡皮圈和咬合涡轮消除牙弓形态的不调，她的美观和功能效果得到改善。锥形束 CT（CBCT）和关节间隙指数（JSI）分析作为治疗前后的诊断方法和疗效评估方法。
结论
髁突位置的移位可能是功能偏斜的一个指征。JSI 分析是比较髁突相对位置的一种定量且方便的选择。
