骨突

Results: In the experimental group, both TBV%(the fraction of trabecular bone volume) and MTT of the condylar subchondral bone were significantly decreased, whereas the RS%(the fraction of resorptive surface) and OS%(the fraction of osteoid surface) significantly increased.

结果：实验组大鼠髁突软骨下骨小梁相对体积减小，平均宽度变薄，而骨小梁吸收表面百分比与类骨质表面百分比比对照组均增加。

Objective The most common site of heamorrhage in maxillary osteotomies is the posterior maxilla.

上颌骨、腭骨及蝶骨的翼突联合形成翼腭管和翼腭窝，其中有神经血管束通过。

Cysts form anywhere in the incisive canal located in the palatine bone and behind the alveolar process of the maxillary central incisors, or in the palatal soft tissues that overlies the foramen, called the cyst of the incisive papilla.

无论是在切牙管任何位置的囊肿都位于上颌骨，上颌骨中切牙牙槽突的后方，或者在覆盖于壳顶孔上方的软组织内，这种又被称为龈乳头囊肿

Methods: The operation procedure included frustration and elevation of the nasal bone and part of the forntal process of maxilla and replacement of the nasal septum between greater alar cartilages.

本手术通过凿断鼻骨及部分上颌骨额突揿压折断使其耸立以抬高鼻背和移植自体鼻中隔软骨以增高鼻尖或鼻翼，一次性完成鼻外形的整体修复。

Objective To evaluate the outcome of alveolar cleft bone grafting using dental 3D-CT, and identify the position of the bone bridge.

目的 应用牙CT对牙槽突裂植骨术后的骨桥位置进行定位分析。

Our study broke through the traditional method of treating alveolar cleft with bone grafting. According to the characteristics of DO, transport disk was used to close the cleft and stimulate the new bone deposition behind it.

本研究旨在突破传统牙槽突植骨术治疗牙槽裂的思路，根据牵引成骨技术的特点，实验采用输送盘关闭裂隙，同时刺激新骨产生。

MAIN OUTCOME MEASURES: At 3, 7, 14, 28 days after the application of traction and 3, 7, 14, 28 days after the removal of traction, the expression of receptor activator of nuclear factor κB ligand/osteoprotegerin in the subchondral bone of the bilateral condyles was analyzed by semi-quantitative immunohistochemistry.

主要观察指标：加力3，7，14，28 d及撤除外力后3，7，14，28 d，以免疫组织化学半定量检测双侧髁状突软骨下骨中核因子κB受体活化因子配基/骨保护素表达。

It is further confirmed by the experiment of muti-inducement that MSMPs can differentiate into osteocyte sand fibrocartilage cytes and it is osteo-chondro progenitor cells with the potential ability to evolve muti-differentiated. This added evidence to the view that condylar cartilage differentiated from osteo-chondro progenitor cells in the mesenchymal cells of mancibular periosteal.

体外分离培养鼠胚下颌体骨膜间质细胞并研究其生物学特性，通过多向诱导实验进一步证实：下颌骨膜间质细胞可能为骨—软骨的前体细胞，可分化为成骨细胞及纤维软骨细胞，具有多向分化潜能，此结果进一步支持髁突软骨是由下颌骨膜间质中骨—软骨前体细胞发育而来。
