Abstract

The push test method showed higher shear bond strength values than the pull test method. 2. A bond strength of 4,500 to 6,000 psi between the dental stone and metal rod was eliminated in a waxed-rod test. Although the strength values were lower in waxed-rod tests, they were believed to be true shear bond strength values. 3. Shear bond strengths of 12,000 psi in push tests and 9,700 psi in pull tests were observed in Ceramco porcelain fused to Ceramco gold.

摘要

推测试法显示出比拉测试法更高的剪切粘结强度值。2. 在蜡棒测试中，牙石与金属棒之间4500至6000磅力/平方英寸的粘结强度被消除。尽管蜡棒测试中的强度值较低，但它们被认为是真实的剪切粘结强度值。3. 观察到Ceramco瓷熔附于Ceramco金时，推测试中的剪切粘结强度为12000磅力/平方英寸，拉测试中的为9700磅力/平方英寸。
