Finite Element Analysis of Stress Distribution on Condyloid Process after Internal Rigid Fixation of Mandibular Angle Stabilizing Fracture

下颌角稳定型骨折坚强内固定后对髁突影响的有限元分析

And the bone density of mandibular angle can reflect the bone density changes of bone mandible.

用这种骨密度仪测量下颌角的骨密度具有可行性和实用性,所测结果能反映下颌骨的骨密度变化.

The retromandibular vein combined with facial vein to form an arch structure, which surrounded the mandibular angle.

下颌后静脉与面静脉吻合后形成一弧形结构包绕下颌角；

Methods 102 cases of prominent mandibular angle patients who had mandibular angle osteotomy in Plastic Surgery Hospital were examined by three-dimension CT and three-dimension cephalometry were carried out.

方法：对102例在中国医学科学院整形外科医院颅颌面中心行下颌角截骨整形的患者做三维CT检查，并对其颅面结构进行三维立体测量。

Methods The operations of angle splitting ostectomy have been performed on 13 patients ( 11 female, 2 male) who had large, squarish, or broad face with eversion mandibular angle.

方法对下面部宽大，下颌骨体肥厚，下颌角外翻明显的四方脸者（13例，其中男性2例，女性11例）进行了下颌骨体部的劈裂截骨术和部分咬肌去除术。

Objective To observe the results of Intraoral curved osteotomy for mandibular angle prominence.

目的:观察下颌角肥大口内弧形截骨的手术效果.

Objective: To explore and analyse the relative factors of the mandibular angle fracture.

目的：探讨和分析下颌角部骨折的相关因素。

When the mandibular body fracture is under the premolar and molar of fracture side occlusion 、 the mandibular angle fracture is under the molar of fracture side occlusion, the stress of the upper fracture part is bending force and the lower is compressing force.

体部骨折患侧前磨牙、磨牙咬合以及角部骨折患侧磨牙咬合情况下，骨断层应力分布显示下部为张力带、上部为压力带。

Conclusion: The change of stress in condyloid process, after internal rigid fixation of mandibular angle stabilizing fracture, may damage the biomechanical environment of condyle and it may be one of reasons that cause to TMD.

结论：下颌角稳定型骨折在外斜线行坚强内固定后髁突表面应力分布发生了异常改变，破坏了颞下颌关节的生物力学环境，可能是下颌骨损伤后颞下颌关节紊乱病的致病原因之一。

Objective To investigate the causes and treatment of the asymmetric prominent mandibular angle.

目的探讨不对称性下颌角肥大的原因及手术治疗.

Methods: Measuring the bone density of mandibular angle and coxofemoral region with dual energy X ray absorptiometer ( DXA).

方法：采用双能X线吸收测量仪（DXA，骨密度仪），测量右侧髋部与左侧下颌角的骨矿物密度。

Reduced mandibular angle anaplasty through the intraoral route with a tiny additional extraoral incision

口内切口辅以微小口外切口下颌角缩小整形术

Conclusion: Through intraoral route with an tiny additional extraoral incision the prominent mandibular angle was grinded is a useful, well resulted method.

结论：口内切口辅以口外微小切口下颌角缩小是易操作、瘢痕小、效果好的手术方法。

Conclusion The eversion of the mandibular angle is an important factor to determine the bigonial breadth.

结论正常下颌角有一定的外翻角度，外翻角度是决定下颌角间宽的主要原因。
