下颌骨各部骨化时间为8～36周，骨化部位最早的为下颌体，最晚的为颏结节。

The occuring time of the ossification of mandibula lasted 8-36 weeks . The first part was corpus mandibulae , and the last part was tuberculum .

最低血氧饱和度的改善仅与下颌体长度及舌根部前后位置显著相关；

The improvement of the lowest SaO 2 was only correlated significantly with the body length of the mandible and the anteroposterior position of the base of tongue .

结论：固定斜面导板可以刺激下颌体生长，改善面部比例关系，是一种有效的打开咬合，调整牙合位的装置。

Conclusion : Fixed inclined bite plate is effective in the improvement of sagittal skeletal relationship and in the orthodontic treatment in the juveniles with Class ⅱ division 1 malocclusion .

方法采用光密度分析软件分别测定三叉神经痛患者以及健康人群全景片下颌体部标定区域内的光密度，按年龄、性别进行对比分析，观察两组骨密度的变化情况。

Methods The software of bone mineral density was used to detect both patients with trigeminal neuralgia and the normal subjects ′ bone mineral density of the mandibular definite zone through DPT .

高角组下颌体及下颌升支长度小于均角组，均角组小于低角组。

The mandibular body length and the mandibular ramus in high-angle group is shorter than the average-angle group , the average-angle group is shorter than the low-angle group . Conclusion : 1 .

结论：1.青年女性下颌体截面高度、宽度、皮质骨厚度从中线至远中呈现出一定的规律。

There are some regularity from the media to the distance of the height , width of the mandibular cross-sections and the thickness of the cortical bone of the young females . 2 .
