Place a crown removal hole in the occlusal surface of the crowns. 放置一个冠洞,去除咬合面的克朗。
Objective: To observe the effects of different root canal file and the restoration of occlusal surface on the fracture resistance of premolars. 目的:观察不同根管锉预备根管及不同面充填物对前磨牙牙体抗折强度的影响。
Result: To set loads or constraints on the occlusal surface have significant different on the results, but the loads or constraints set on the masseter muscle attachment area have not. 结果:对牙列咬合面进行加载还是进行约束其结果差异较大,而咬肌附丽处进行加载还是进行约束其结果无差异。
Considering the complexity and non-convexity of the occlusal surface, a fast collision detection algorithm based on the image space is introduced. 然后鉴于牙合面结构的复杂性和非凸性,引入了一种基于图像的快速碰撞检测方法,用于检查上下颌牙齿的对位情况。
Most caries were minor in degree of severity, and mostly lie in the occlusal and proximal surface. 龋齿主要为浅龋,咬合面和邻面龋占绝大多数。
The vertical distance between the lowest point of pulp chamber roof and occlusal surface in non-tooth-wear group was greater than that in tooth-wear group ( P < 0.01); 无磨损组髓顶最低点到牙合面的垂直距离大于磨损组;
Group ⅲ: including 18 teeth with deep carries on their occlusal surface, representing the weak functioning ones. Ⅲ组:牙合面深龋组,18个,代表功能减弱组。
A study of three-dimensional finite element of three kinds of occlusal splints effect on the surface stress of condyle 三种夹板对髁状突表面应力影响的三维有限元研究
Conclusion Long-term chewing betel nut can result in the abrasion of occlusal surface. 结论:长期咀嚼槟榔可导致牙体牙合面不同程度磨损。
Abrasion and widen periodontium ligament were detected on the occlusal surface and X Ray photos respectively both on 30 and 60d group. 30d及60d组可见受伤牙咬合面磨损,根尖X片显示牙颈部牙周膜腔增宽。
Virtual Adjustment of the Occlusal Surface of Dental Restorations 口腔修复体咬合面虚拟调整
Objective: Using an in vitro study of the penetration and adaptation of pit and fissure sealant after pulse Nd: YAG laser etching the pits and fissures in occlusal surface of human premolars, to explore the utilization of laser etching in pit and fissure sealing. 目的:通过研究脉冲Nd:YAG激光蚀刻面窝沟后窝沟封闭剂的渗透性和密合性,探讨激光蚀刻在窝沟封闭中的应用价值。
Objective: To investigate the influence of occlusal surface morphology on stress distribution in the base of maxillary complete dentures ( MCD). 目的:探讨异常牙合面形态对上颌全口义齿基托应力分布状况的影响。
Adjustment of occlusal surface is a crucial problem and a technical difficult in the whole CAD system of dental restorations. 修复体面咬合调整是整个口腔修复体CAD系统中的关键问题和技术难点。
