Dynamic analysis of root fracture with high speed camera

研究并建立了最高分辨率的最佳数目条件，以便在照相速度限制下获得最高分辨率，从而可以用高速相机检查裂纹的进展过程。为了分析不同搭桥法对桥台断裂作用的影响，对不同搭桥法材料的基本物理性能进行了测试。可以从以上结果中寻找今后临床研究中所需要的基台施工对象物理性质的最佳摄影条件和高速相机。

The conditions of the optimal number of the highest resolution were examined and set up so that the highest resolution might be obtained within the limits of the photography speed which can check the process of crack progress using a high speed camera. In order to analyze the fracture action by the difference in the abutment build up method, the fundamental physical properties of various materials used for abutment construction were measured. The optimal photography conditions of the physical properties of a abutment construction object and a high speed camera that are needed from the above result when performing clinical study from now on were able to be searched for.
