前突的

Some serious skeleton abnormals as above before the Han Tu, descend before the Han Tu and open Han etc. needed to be carried on before the awkward age arrives to correct and cure the development that then can stop wrong Han in early days, the guide tooth, Han bone grew as usual.

有些严重的骨骼畸形如上颌前突、下颌前突、开颌等需要在青春期到来之前进行早期矫治才能阻断错颌的发展，引导牙齿、颌骨正常生长。

Results: When the slide segment was retained 1 mm width,the fifth cheek tooth and anterior edge midpoint of condyle process anterior slope and coracoid process showed negative displacement and the angle of mandible and the posterior edge midpoint of condyle process posterior slope showed positive displacement on x axes.

结果：在牵张过程中牵张侧下颌骨标志点位移趋势为在内外方向上第五臼齿、喙突、髁状突前斜面前缘中点的运动趋势是向外的，而下颌角、髁状突后斜面后缘中点的运动趋势是向内的；在前后方向上第五臼齿、喙突的运动趋势是向后的，而下颌角的运动趋势是向前的；在上下方向上第五臼齿的运动趋势是向上的。

Three cases of kyphosis were secondary to L1 hypoplasia, and four were secondary to L2 hypoplasia.

开始时的后突角度是34.2°，最后随访时进展到脊柱前突0.4°。

Maxillary teeth were retracted,and the overjet and overbite were adjusted to right relations,and soft convex tissues face type was improved.

上颌牙齿前突减数矫治，有助于上颌和上牙弓的突度减小，使软硬组织面型之间的形态结构一致，特别对上牙弓突度的改善是肯定而持续的。

The relative timing between the presynaptic and postsynaptic spiking determined the direction and the extent of synaptic changes.

在前突触与后突触的相对尖突激发时间，决定了神经突触改变的程度与方向。

Methods From January 1997 to January 2005, 95 patients suffering from mandibular prognathism or accompanied by other deformities have been operated on by technique of intraoral SSRO in our hospital were studied.

对1997年1月～2005年1月于我院采用下颌升支矢状劈开截骨术矫正的下颌前突及下颌前突合并其他部位畸形患者95例术后并发症进行回顾性分析。

Results:The oculomotor nerve entered into cavernous sinus at 7.8±2.1 mm anterolateral to posterior clinoid process and 5.0±2.0 mm posterior to superior segment of clinoid process of internal carotid artery.

结果：动眼神经入窦点在后床突的前外侧7.8±2.1 mm，在颈内动脉床突上段后方5.0±2.0 mm处。

Medullary branch of precentral gyrus is on 1-2 clock of dial plare and postcentrai gyrus is on 2~3 clock of dial plate from this section.

从此层面开始分别套用两个表盘，自额顶叶髓质向上外(12点～3点位)发出宽大的中央前回的髓突，向外下方(3点～4点)位发出薄的中央后回的髓突，中央后回明显薄于中央前回。

In this study, we use Computer Aided Diagnosis Axiogragh recorded condylar movement of normal occlusion and Angle class two division one subdivision malocclusion with mandibular retrusion every twenty-five during mandible open and close, protrusion and retrusion, and medio-free movement. Then we analysis the deference in order to find out the characteristic of condylar movement of Angle class two division one subdivision malocclusion with mandibular retrusion and the change regularity among befor and after functional appliance treatment.

本研究以正常牙合和下颌后缩型安氏Ⅱ类1分类错牙合各25名为研究对象，采用髁突运动轨迹轴图描记仪(Computer Aided Diagnosis Axiogragh)记录其下颌在开闭口、前伸后退和侧方运动时髁突的运动情况，对比分析下颌后缩型安氏Ⅱ类1分类错牙合的髁突运动轨迹特征及其功能矫治前后髁突运动轨迹的变化。

Results The anterior bundle of ulnar collateral ligament originates from the inferior aspect of the medial epicondyle and inserts immediately adjacent to the joint surface on the ulna near the sublimis tubercle. The posterior bundle originates from the medial epicondyle slightly posterior to its most inferior portion and inserts broadly on the olecranon process. The lateral collateral ligament arises from the inferior aspect of the lateral epicondyle. Two types of conjoined lateral collateral and annular ligamentous insertions on the ulna were observed. Type Ⅰ(61.2％) was bilobate and type Ⅱ(38.8％) was a single broad conjoined type with insertion on the ulna. The anterior band of anterior bundle was more tighten than the posterior band as the elbow flexed less than 60°. When the elbow flexed over 60°, the two parts of anterior bundle were equally tightened. The posterior bundle was tightened as the elbow was flexed more than 90°. The lateral collateral ligament was tightened gradually as the elbow moved in flexion.

结果(1)尺侧副韧带前束起于肱骨内上髁的前下方，止于尺骨冠突内侧的小结节；后束起于肱骨内上髁的内下方，止于尺骨鹰嘴内侧的骨面；(2)桡侧副韧带起于肱骨外上髁的外下方，其纤维部分止于环状韧带，部分止于尺骨冠突的外下方；桡侧副韧带和桡骨环状韧带在尺骨上的止点有两种类型：Ⅰ型占61.2％，桡侧副韧带的部分纤维汇于环状韧带的尺骨止点，另一部分纤维单独止于稍远的尺骨上；Ⅱ型占38.8％，桡侧副韧带和环状韧带形成一宽的纤维止于尺骨上；(3)在肘关节屈曲60°以前，尺侧副韧带前束的外侧部紧张而内侧部较松弛，肘关节屈曲超过60°后，前束内外侧处于同程度的紧张状态；尺侧副韧带的后束在肘关节屈曲超过90°后才被拉紧；(4)桡侧副韧带在肘关节不同屈曲状态时其紧张度逐渐增加，当肘关节屈曲超过90°时，桡侧副韧带被明显拉长。
