Conclusion.Reconstruction of longitudinal and transverse supporting pillars of midfacial skeleton were the key procedure in management of dentom axillofacial deformities.

面中份陈旧性骨折牙颌面畸形外科矫治的关键是对面部纵向和横向骨支撑结构的重建以恢复其固有的高度和突度。

Methods There were 86 cases of midfacial fractures treated withdifferent operations in different stages (primary, delayed and secondary stages) according to their conditions.

手术方法主要通过原伤口、冠状切口、眶周小切口及口内切口联合入路，暴露骨折断端，分离后以下颌骨作为参照，在建立良好的咬关系的基础上，恢复和加强眶上颌颧骨复合体三对垂直颅颌支柱及二个水平轴。

The purpose of this article was to quest for the feasibility of surgical techniques on midfacial fracture.Methods.103 cases who had dentomaxillova cial deformities following midfacial fracture were retrospectively investigated. Results.

本组103例均为由于面中份的多发性骨折、粉碎性骨折或因各种原因未能及时治疗，骨折块之间已发生错位愈合而导致牙颌面畸形的患者，根据畸形情况采用不同的术式切开复位固定。

LeFortⅠosteotomy is an important surgical method in midfacial obsolete fractures management. The cephalometric radiography and model surgery should be performed depending on the principles of orthognathic surgery before LeFort Ⅰosteotomy. The other fractures of facial bones besides maxilla should be managed surgically in the same operation.

LeFort Ⅰ型截骨术是治疗陈旧性面中部骨折的重要手术方法，术前应依照正颌外科原则进行X线头影测量和模型外科准备，术中应同期进行上颌骨骨折之外的其他面骨骨折的复位固定。

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。

METHODS: Three-dimensional finite element mandible model was established based on the CT scanning data. The mini-implant was implanted in the region between first mola and second premolar at 30°, 60° and 90° tilted mesiolly, and 30° and 60° tilted occlusally, respectively.

应用颌骨CT扫描图象建立三维有限元模型，在下颌第1磨牙及第2双尖牙间分别以牙合向30°，60°，90°，近中向30°，60°植入种植体，给以水平方向1.96 N 加载。

TPA and Nance arch is a simple and effective production of the increase in the mouth anchorage devices,for bimaxillary protrusion of the patients it is a very effective.

TPA和Nance弓是一种制作简单的、有效的、增加支抗的口内装置，对双颌前突的患者疗效显著。

There may be more extra-landm ark noise associated with the measurement of angle NAPg than with the other thre e angles.Since change in SNA is affected by Nasion horizontal displacement,its r epresentation of Point A displacement was questionable.

除了NAPg，其它3个角度的变化基本能反映出颌骨及牙齿在矢状方向的位置改变，但SNA角的变化在一定程度上同时受N点水平向位移的影响，使其反映A点水平向位置改变的可靠性受到影响。

Objective: To study the value of CT examination in the diagnosis of neoplastic lesions of jawbones.
