特异性髁突吸收的研究现状与进展

Status and advance of idiopathic condylar resorption

特异性髁突吸收（ICR）是指不明原因引起的髁突吸收、髁突高度降低、牙颌面形态发生变化的骨吸收性疾病，多发于15—35岁的骨性Ⅱ类错骀畸形，伴有前牙开牙台、高牙台平面角及下颌平面角、下颌后缩的女性患者。本文就ICR的病因、诊断、治疗综述如下。

Idiopathic condylar resorption （ICR） is a poorly understood progressive disease that affects the temporomandibular joint and that can result in a loose of condylar height and alteration of the maxillofacial morphology and occlusion. It often affects females age 15 to 35 years old. Maxillofacial morphological findings generally include： Angle Class II malocclusion with anterior open bite; high occlusal plane angle and mandibular plane angle; mandibular retropositioning. In recent years, good progress on the study of ICR was achieved. This review focused on the pathogenesis, diagnosis and treatment of ICR.
