Objective To study the influence of BSSRO on mandible ramous and temporomandibular joint.

目观察双颌骨矢状劈开截骨术(BSSRO)后移颌骨对颌升支及颞颌关节影。

The two most commonly used surgical techniques to setback a prognathic mandible include the bilateral sagittal split osteotomy and the vertical ramus osteotomy.

最普遍使用正颚手术方法来改善颚骨前突症方法是双矢向面骨切开术及垂直颚枝骨切开术。

Rest vertical dimension is the lower face height measured from chin point to nasospinale, with the mandible in rest position.

垂直距离概念可以是指颌位于姿势位时这两个标志点之间距离，主要与肌功能有关。

The mandibles are usually lost, the labrum is reduced to a narrow transverse sclerite, and the labium is a small flap ( though its palps retain quite large).

上颚消失，上唇退化为一条窄横片，唇退化为一小片（唇须发达）。
