objective:to evaluate the clinical effectiveness of titanium plate osteosynthesis in maxillofacial fractures.methods:216 maxillofacial fractures in 157 cases from 1998 to 2005 were treated with titanium microplate or miniplate osteosynthesis,122 of which were mandibular fractures and 94 of maxillary fractures.43 cases of maxillofacial fractures including cranial injuries in 157 cases and 38 cases including zygoma and zygomatic arch fractures and 13 cases including other injuries.results:most of the cases were healed.only 9 cases had complications.conclusion:the titanium plate osteosynthesis would bring about good effects.it would reduce facial malformation and regain normal occlusion after operations.

目的：对应用钛板作骨内坚固内固定的效果进行临床评价。方法：自1998年－2005年收治157 例共计216处颌骨骨折进行微型钛板或小型钛板作骨内坚固内固定术。其中下颌骨骨折122处；上颌骨骨折94处。157 例颌骨骨折合并颅脑损伤43 例，伴有颧骨弓骨折38 例，伴有其他外伤13 例。结果：多数病例能达到一期愈合，仅9 例伴有并发症。结论：钛板内固定具有良好的效果，术后面颌畸形得以改善，咬合功能恢复。

If the condylar fracture is treated inappropriate, it may cause some complications, eg: limitation of mouth opening, pain in TMJs, occlusion disorder, arthrocleisis and so on. The fractural condylar can't rebuild well without treatment. For any kind of condylar fracture, treatment should strive for anatomic replacement and avoid removing the fractural residual.

研究结论：髁状突骨折如治疗不当，容易出现一些后遗症或并发症，如张口受限、关节区疼痛、咬合错乱以及关节强直等；成人髁状突骨折如不作处理，并不能自行改建形成新的功能完好的关节；所有类型的髁状突骨折，治疗时都应争取达到解剖复位，不应轻易摘除骨折残端。

In 1970s Champy et al reported a new treatment of mandibular fracture using miniplate system, which could avoid an external scar and reduce the complications of malocclusion due to placed transorally and easily bended to suitable to the surface of the mandible.

小型夹板骨折固定技术是20世纪70年代Champy等学者提出和发展起来的一种新的骨折固定方法，这种固定方法可以通过口内手术途径植入固定体，避免了术后皮肤瘢痕，而且夹板的形态容易弯制使之与下颌骨表面相一致，术后咬合错乱的发生率减低。

AIM: To investigate the influences of occlusal vertical rising on condylar cartilage remodeling in adolescent rats.

目的：探讨升高咬合对青春期大鼠髁突软骨改建的影响。

Emergency surgical treatment of open condylar fracture is beneficial to healing of condylar fracture and reduction of occlusion.

对开放性髁突骨折患者，急诊手术更有利于骨折愈合及咬合关系的恢复。

Methods Autogenous costochondral grafts were applied in the reconstruction of the temporomandibular joint in 27 cases with condyle ankylosis from 1988～1998.The follow up period was 1～10 years.The pre-and post-operative degree of mouth opening and the TMJ function was examined.

采用自体肋骨、肋软骨移植对27例颞下颌关节真性强直患者进行了关节重建术，术后随访，计算手术前后张口度的差值，检查咬合关系、下颌前伸和侧向运动功能，行关节X线检查。

Methods Through gathering 34 patients of adult maxillary median diastema,we applied compositive treatment of orthodontics, prosthetics and operations to restore patients?appearance and occlusion relationship.We used Down抯 method to carry out cephalometrics measure and analysis for successive contrast of operations.

通过收集上颌正中间隙患者34例，运用正畸、修复和手术综合治疗方法恢复患者外观和咬合关系，术前后Downs方法进行头影测量分析。

Different operative methods were used according to the type of hemifacial microsomia, All the patients obtained satisfactory facial appearance and oral functioin. with pre- and post-operative orthodontic treatments.

（1）畸形同时具有骨性畸形和软组织畸形，根据畸形的不同类型运用相应的手术方案，配合术前术后的正畸治疗，可获得咬合关系和容貌均满意的临床效果。

Studies were done to establish the average distance from the incisal or occlusal surface of the tooth to the center of the clinical crown.

研究建立进行了平均距离切或咬合面的牙齿的中心临床冠。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
