To compare condylar position and morphology among different vertical skeletal patterns.
Diagnostic cone-beam computed tomography images of 60 adult patients (120 temporomandibular joints) who visited the orthodontic clinic of Hallym University Sacred Heart Hospital were reviewed. The subjects were divided into three equal groups according to the mandibular plane angle: hypodivergent, normodivergent, and hyperdivergent groups. Morphology of the condyle and mandibular fossa and condylar position were compared among the groups.
The hypodivergent and hyperdivergent groups showed significant differences in superior joint spaces, antero-posterior condyle width, medio-lateral condyle width, condyle head angle, and condylar shapes.
Condylar position and morphology vary according to vertical facial morphology. This relationship should be considered for predicting and establishing a proper treatment plan for temporomandibular diseases during orthodontic treatment.
比较不同垂直骨面型患者髁突的位置及形态。
回顾分析60例成年患者（120个颞下颌关节）的锥形束计算机断层扫描（CBCT）诊断影像，这些患者均就诊于翰林大学圣心医院正畸科。根据下颌平面角将研究对象平均分为三组：低角组、均角组和高角组。比较三组髁突、下颌窝的形态以及髁突位置。
低角组和高角组在上关节间隙、髁突前后径、髁突内外径、髁突头角度及髁突形态方面存在显著差异。
髁突位置及形态随面部垂直形态而异。正畸治疗中预测和制定颞下颌疾病的合理治疗方案时应考虑这种关系。
