研究了复合树脂与磷酸蚀刻搪瓷棱镜的纵、横截面的拉伸结合强度。牙釉质晶面的拉伸强度受牙釉质晶面性质的影响，横向为18 ~ 19 MPa，纵向为10 ~ 11 MPa。这些事实表明，如果给予牙釉质壁边缘形式以产生牙釉质棱柱的横向截面而不是纵向截面，则复合树脂修复体的寿命将更长。
The tensile bond strengths of composite resins to transverse and longitudinal sections of enamel prisms etched with phosphoric acid were examined. The tensile bond strengths were 18-19 MPa to the transverse and 10-11 MPa to the longitudinal sections and thus were influenced by the nature of the enamel crystal planes. These facts suggest that composite resin restorations will have a longer life span if the enamel walls are given marginal forms to produce transverse rather than longitudinal sections of enamel prisms.
