Among the different incisal reduction designs there was no significant Von Mises stress variation under the same load condition. However, when the incisal edge was reduced by more than 4 mm, the tensile stresses in the bonding layer greatly increased. 当加载条件相同时,各相同切端减少组粘结层VONMISES应力值变化不大,但当切端减少大于4mm时粘结层拉应力有明显增高。
