mandible

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

目的观察双侧下颌骨矢状劈截骨术(BSSRO)后移下颌骨对下颌升支及颞下颌关节的影响。

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

垂直距离的概念可以是指下颌位于姿势位时这两个标志点之间的距离，主要与有关。

3.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，下唇退化为一小片（下唇须发达）。
