关于创伤He的计算机辅助光He研究

为了定量研究创伤Ｈｅ，确定可以协助临床诊断咬合病人客观指标及鉴别正常Ｈｅ与创伤Ｈｅ的依据。方法 利用计算机图像处理技术，自行编制计算机软件程序及硬件系统用于光Ｈｅ分析，可全面提取，分析咬合信息。结果 可识别每个牙及全牙列的咬合接触区数目，面积，接触应务和接触力等定昨指标，能准确，迅速地评价咬合的性质与状态。

Computer aided photocclusion analysis of traumatic occlusion]

OBJECTIVE: This study was designed to analyse traumatic occlusion quantitatively. METHODS: A photocclusion method using computer image processing technique is described, the processing software provide the occlusal contact area, contact point numbers, contact force, maximum stress, and average stress distribution of all teeth by tables and figures. RESULTS: (1) The traumatic contact area was larger and contact force was greater than that of the normal occlusal contact. (2) There was an irregularity force distribution from molars to incisal area. (3) The symmetrical distribution of contact forces and contact areas were destroyed. CONCLUSION: Computer aided-photocclusion method can be used to diagnose traumatic occlusion.
