牙周膜

The results were examined histologically 1 month and 3 months respectively. In experimental groups the JE downgrowth was inhabited in the early healing, and the new attachment formation was promoted while comparing with controls.

结果与对照组比较，FG、ePTFE膜组和e-PTFE膜+FG组均可显著促进根分叉区牙周组织的再生，且FG、ePTFE膜组之间没有显著差异，而e-PTPE膜+FG组在一月时可更好的促进牙槽骨的再生。

It can be used to make artificial dialysers,artificial skins,oral ulcer membranes,and periodontal tissue GTR membranes and drug membranes.

Thirty-six rats ,weighing(250±10)g, were randomly divided into normal group, experimental group and control group.Orthodontical devices were put between the upper incisor teeth and dens molaris in both experimental group and control group.The corrective force was adjusted to 60g.Salvia miltiorrhiza combination was implanted to each rat in the experimental group every day.The animals of both experimental group and control group were killed at 7,14 and 21 days.The upper dens malarias and periodontal tissue slices were observed under the light microscope and transmission electro microscope,and the X-ray dental films were taken and measured with digitization dental scanning apparatus and its software.

以36只体重(250±10)g的雄性大鼠为样本，随机分为正常组、实验组和对照组，设定不同浓度丹参复合膜，以同体对照方式在正常组进行体内植入实验，在2周内观察不同浓度丹参的牙周组织诱导作用，寻找最佳应用浓度；在实验组和对照组的上切牙与磨牙之间隙安装正畸装置，建立大鼠磨牙移动实验模型，矫治力的大小为60g；实验组每日每只体内植入丹参复合生物膜，两组动物于正畸加力7、14、21d，分三批处死；处死后立即切取双侧上颌磨牙及牙周组织制取标本，制片透射电镜和光镜观察；拍摄X线牙片，用数字化牙科扫描仪及软件对其进行测量分析。

Results:The 3-dimensional finite element models of the minimum distal occlusal structure defect with restoration were created, which included metal crown with exterior anatomic morphology of the mandibular first molar, tooth preparation, filling material and the structure of periodontal membrane.

本研究采用逆向工程技术，通过先进的三维激光扫描技术，三维造型设计技术建立几何模型，将几何数据导入有限元分析软件中，建立了右下颌第一磨牙具有根管和远中面(distal occlusal，DO)最小缺损的全冠修复牙体预备体、充填体、金属冠、牙周膜的三维有限元模型。

The normal strain on the surface of the periodontal ligament is assumed as the mechanical stimulus proportional to the absorption rate of alveolar bone in each week.

选用一个正畸患者的下颌尖牙，建立包括牙齿、牙周膜、牙髓、牙槽骨的三维实体模型，通过有限元计算得到初始应变分布。

Results: There were no significant differences between the healing process of frozen ATMC and that of fresh ATMC, and the fibres of regenerated periodontal membrane which maintained the dental root in normal position could be imbedded in the newly formed cementum.

结果：两组自体牙-下颌骨复合组织块移植后愈合过程相似；再生的牙周膜将牙根维持在原来的位置上，牙根尖发生轻微吸收。

Fixed prosthodontics did not change the stress and strain distributions of abutment periodontal ligament but just made the values increased.

固定桥的修复基本没有改变基牙牙周膜的应力和应变分布规律，但使上述值明显增大。

In the treatment of impacted third molar, dental practioner and oral surgeon more often think about how to extract the third molar completely, but rarely consider to add some procedures such as distal wedge, alveoloplasty, guided tissue regeneration, and apically repositioned flap etc., to prevent 2nd molar from developing periodontitis. The latter procedures can reduce its accompanying deep pocket, to remove plaque and calculus on its diseased root surface.

在治疗阻生第三大臼齿，诊所执业医师和一般口腔外科医师较常会考虑怎样把阻生第三大臼齿完全拔除，但却较少考虑在拔除阻生第三大臼齿的同时做一些措施，像远心楔形手术，齿槽骨整形术，引导组织再生术和牙周办膜根向移动术等来预防第二大臼齿远心端形成牙周炎，或同时替第二大臼齿治疗深的牙周囊袋和去除其牙根表面的牙结石和牙菌斑。
