the rigidity of the prostheses doesnt increase as the rigidity of materials increases if the thickness of the axial surface is enough.
而在保证修复体一定的轴面厚度时,增强材料的刚性并不能使修复体的刚性随之增强。
the structural model should be built in 4 steps with the axial surface analysis as the basis, the fault-fold geometric analysis as the key, the balanced idea as the guidance and the stru.
