计算了牙本质粘接系统中作为树脂复合材料粘结部位的粘结区在剪切粘结测试中的平均应力和在纳米压痕测试中的变形行为。首先计算牛牙本质与复合树脂粘结区域的平均应力。其次，利用弹塑性变形区模型计算了纳米压痕试验后的塑性变形区尺寸。结果表明，平均应力取决于粘结区的弹性、复合树脂与粘结区的弹性比以及牙本质与粘接树脂之间的界面应力。在该键合区域中，弹性/硬度比随键合区域的厚度以及塑性变形区大小(B)而变化，表示为a(b/2a)值(纳米压痕试验中的压痕三角形长度(2a))随弹性值的增加而扩展。
Average stress during shear bond testing, and deformation behaviour during nano-indentation testing were calculated for the bonding area as a bonding site for copolymerization with resin composite in dentine bonding systems. First average stress was calculated in the bonding area between bovine dentine and composite resin. Secondly, the plastic deformation zone size was calculated using an elastic/plastic deformation zone model after a nano-indentation test. The result clearly showed that average stress depended upon the elasticity of the bonding area, the elasticity value ratio of the composite resin-to-bonding area, and interfacial stress between the dentine and the adhesive resin. In this bonding area, the elasticity/hardness ratio changed depending on the thickness of the bonding area as well as the plastic deformation zone size (b), expressed as a (b/2a)-value (indented triangular length (2a) at nano-indentation test) expanded with increasing the elasticity value.
