摘要/Abstract

摘要： 目的： 报道1例因活动期单侧髁突肥大致骨性偏颌患者的正畸-关节联合治疗过程。诊治经过： 20岁女性右侧单侧髁突肥大（unilateral condylar hyperplasia,UCH）伴骨性偏颌,右下颌升支较左长约11mm。方案采用“关节手术先行”行右侧髁突等比例切除术阻断生长并纠正垂直不对称,术后即刻应用固定正畸及种植支抗精细调整咬合与中线。结果： 矫治历经29个月,面部不对称显著改善,中线对齐,建立了良好的中性咬合及正常的覆𬌗覆盖,关节功能健康无弹响。结论： 等比例髁突切除联合术后正畸能有效阻断畸形发展,避免术前去代偿带来的面容恶化,实现面部美学、咬合与关节功能的同步重建。

Abstract: Objective: To report the combined orthodontic and joint treatment of a patient with skeletal mandibular deviation caused by active unilateral condylar hyperplasia(UCH). Diagnosis and Treatment: A 20-year-old female presented with right UCH and mandibular deviation; her right mandibular ramus was approximately 11 mm longer than the left. A ‘joint surgery-preceded’ approach was implemented, starting with a right proportional condylectomy to block excessive growth and correct vertical skeletal asymmetry. This was immediately followed by fixed orthodontics and temporary anchorage devices (TADs) for occlusal and midline adjustments. Results: After a 29-month treatment duration, facial asymmetry was significantly improved, midlines were aligned, and a Class I relationship with normal overbite and overjet was established. The temporomandibular joint functioned well without clicking or pain. Conclusions: Proportional condylectomy combined with a ‘surgery-first’ orthodontic strategy effectively halts deformity progression, avoids the presurgical decompensation process, and simultaneously restores facial aesthetics, occlusal function, and joint health.
