Research in the Dental Implant with Ceramic Neck 钛金属陶瓷颈圈牙种植体的研究
Results Three_dimensional surface reconstruction of spiral CT and SSD could clearly demonstrate the dental surface image including crown, root neck and root bifurcation in three_dimensional way, labial or palatal location, eruption orientation and relation with dentition. 结果经CT三维重建和SSD处理后,20例病例均清楚地显示了埋伏牙的牙体形态、唇腭向位置、萌出方向以及与邻牙的关系。
In the research. Research in the Dental Implant with Ceramic Neck 钛金属氧化锆陶瓷颈圈牙种植体的结构强度与生物相容性研究
RESULTS: Finding the vital influencing factors of stress distribution patterns at the bone interface around dental implants, obtaining the regression equation, revealing the quantity's relation between the varieties 'factors and the stress distribution patterns at the bone interface around dental implant neck. 结果:找出了影响种植牙周骨界面应力分布的主要因素,建立了回归方程,揭示了不同影响因素与颈部应力分布规律间的数量关系。
Clinical Analysis of Wedge-Shaped Defect of Dental Neck With Dental Material 牙科材料修复楔状缺损的临床评价
MATERIALS AND METHODS: Using three-dimension finite element method and multivariate step regression analysis, authors analyzed influencing factors on the stress distribution patterns at the bone interface based on the stress magnitudes surrounding dental implant neck. 方法:应用三维有限元和多元逐步回归分析方法,对影响骨界面应力分布的一些因素,根据种植牙颈周骨内应力值进行了统计分析。
At present, all methods exist in some problems, no matter the advanced clinical operate or spraying ceramic on dental implant neck and ceramic abutment etc. 目前无论是从改进临床技术操作还是喷涂陶瓷于种植体颈部以及陶瓷基桩等方法来改善前牙区灰色,都存在一定的问题。
