下颌前的

Methods Four three-dimensional finite element models were constructed by the data of spiral CT:1Mandibular second premolar restored directly by full crown;2Fill the perforating cavity with resin material and full crown restoration;3Cast nickel chromium alloy post core plus full crown restoration;4Fiber post and resin core plus...

方法采用螺旋式CT扫描获取数据，建立下颌第二前磨牙4种情况下的三维有限元模型：1直接全冠修复；2用树脂材料充填开髓洞形后全冠修复；3铸造镍铬合金桩核与全冠修复；4纤维桩树脂核与全冠修复。

The skeletal system showed a series of evolutive characteristics, for example, it had one premaxillary and one frontal bone, the malaris disappeared, the squamosal became smaller, the vomer became thinner, the suturae between the dentary and splenial and the suturae between the coronoid and angular was blurry.

表现出了一系列进化特征，如前颌骨愈合成1块，额骨也愈合成1块，颧骨消失，鳞骨变小，犁骨薄弱，下颌夹板骨与齿骨、冠状骨及隅骨之间的骨缝不明显，愈合程度较高。

All patients were evaluated by dysarthria assessment made by The China Rehabilitation Research Centre before and after treatment.Results: The motor functions of phonatory organ and the ability of speech were improved.

结果：治疗后患者构音器官的运动功能明显改善，口角下垂、嘴唇力量、舌、下颌运动异常及流涎都有不同程度改善（80%~100%）；治疗前29例患者构音处于发单音和单词水平，治疗后仅2例患者构音在单词水平，36患者达句子和文章水平。

Because this produces peculiar tooth jaw face to misshape, constant expression is mid development undesirable reach cave, length of direction of around of bone of the upper jaw and perpendicular direction height shorten, tooth bend is narrow, the tooth lists jam, occlusive relation is disorder, anterior teeth or complete tooth bend are enclothed instead, before mandible true sex or false sex dash forward. 2 use DO method at the back of art of Jiao Zhi cleft palate in the portion caves at the back of art of abnormal cleft palate in the portion caves abnormal treatment method is very much, if Kettle reports block is mental,raise fight a way, the face guard method that Tind Lund uses, wang Ketao [1] uses Peng body to get together 4 fluorine ethylene fills up repair misshapes this kind etc.

因此产生特有的牙颌面畸形，常表现为面中部发育不良及凹陷，上颌骨前后方向长度及垂直方向高度变短，牙弓狭窄，牙列拥挤，咬合关系紊乱，前牙或全牙弓反覆盖，下颌真性或假性前突。2利用DO术矫治腭裂术后面中份凹陷畸形腭裂术后面中份凹陷畸形治疗方法很多，如Kettle报道枕颏支抗法，Tind lund采用的面罩法，王克涛[1]采用膨体聚四氟乙烯充填修复此类畸形等。

Objective: To investigate the effect of insulin on the lateral pterygoid muscle after functional mandibular protrusion in rats.

目的：了解功能矫形前伸大鼠下颌后胰岛素对翼外肌适应性改建的作用。

Results: The amount of insulin in lateral pterygoid muscle in young＞Transfer interrupted!

胰岛素在功能矫形前伸大鼠下颌后翼外肌的适应性改建中有重要作用。

Insulin plays an important role in adaptive remodeling of lateral pterygoid muscle after functional mandibular protrusion.

胰岛素在功能矫形前伸大鼠下颌后翼外肌的适应性改建中有重要作用。

Methods Ten volunteers with experimental premature contact at the first premolar, the first molar and the second molar were asked to clench in CO and their electromyographic activity of the masseters, anterior temporalis and anterior belly of digastric muscles were measured simultaneously.

测定 10名志愿者在正中牙合；左右两侧下颌第一双尖牙、第一磨牙、第二磨牙实验性早接触状态下，嚼肌、颞肌前束及二腹肌前腹肌电活动的积分值与频谱值。

The mechanism was to lead mandibular retrusion and accelerate forward growth of the maxillary.The relief of anterior crossbite combined with the retrusion of condylar and mandible led to the reconstruction of TMJ and nerve- muscles .

前牙反锁结的解除并结合将前伸的踝突、下颌诱导后退，使TMJ、神经肌肉及相关骨骼发生适应性改建，恢复并稳定于正常的关节位，有利于恢复和建立后牙的正常ICP。

All findings indicated that Angle Ⅲ skeletal anterior crossbite can be corrected successfully with reverse TBA combined maxillary protraction.

认为反式TBA联合前牵对上下颌软组织作用均较大，是矫治前牙反牙合的理想装置。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
