摘　　要：随着牵张成骨术适应症的不断扩大,牵张成骨被认为是治疗先天或后天性颌面部缺损的有效手段。由于颞下颌关节与牵引的下颌骨段是一个整体,在牵张成骨过程中,持续的牵引力会传递到颞下颌关节,对其产生不同的影响,然而在不同部位牵张成骨时,髁突所受应力大小和方向却并不尽相同,因此本文将对不同部位牵张成骨对颞下颌关节的影响进行综述。With the expansion on the indications of distraction osteogenesis(DO),DO is thought to be the effective treatment of congenital or acquired maxillofacial defect.Temporomandibular joint(TMJ)and the tractive bone segments are an entirety.During the course of jaw DO,the continuous traction will load on the TMJ,which causes different changes of TMJ.However,the magnitude and direction of the pressures on the condyle are changed with difference parts of mindible.This article will review the effect of different lengthening areas on the TMJ.
