retrusion

Ramus height and condylar width reduced in the mandibular retrusion group, which was a result of condylar growth inhibition during adolescence.

结果：下颌缩组髁突宽度、长度以及升支高度明显较小，说明髁突和升支发育受到抑制。

The tracings of condylar movement in right and left parasagittal planes during protrusion and retrusion were recorded by computer-aided axiography.

结果:侧牙反牙合者前伸退运动轨迹多不重合,反牙合侧前伸髁道斜度明显大于对侧。
