摘要
作者对光 法用于临床口腔医学的光塑性理论──双折射光程差的双本质理论作了深入分析，并且从实验和数值计算两方面对由残余塑性应变引起的双折射光程差δ与外部咬 力Ｐ作了标定。给出了可供临床应用分析的数据参考资料。
This paper discusses the theory of photoplasticity, especially the bi─nature theory of birefringence and the photoocclusion method as the application of photoplasticity in stomatology.The relation between occlusal force P, in another word,occlusal stress σ and the birefringence δ which is caused by the remnant plastic strain is labelled from two aspects of experiments and calculation. This relationship can be used by clinical dentists as guidance or refrential data. By the spectrometic analysis,we find that the photoocclusion wafer can be made with low price,and the analysical equipment can also be made in China.
