Dynamic analysis of root fracture with high speed camera

点击翻译按钮获取中文摘要

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.
