Cemented inlays made of a soft and an extra hard gold casting alloy are subjected to load cycling with 50-200 N. The mesiodistal deflection is determined and marginal leakage is shown by dye penetration. Soft alloy inlays deflect significantly more, nearly 50% exhibit dye penetration caused by microleakage. On average, deflection does not occur with the extra hard alloy, dye penetration caused by microleakage takes place among 25% of the inlays only.
由一种软质和一种超硬质铸造金合金制成的粘结嵌体承受50 - 200牛的载荷循环。测定近远中向挠度，并通过染料渗透显示边缘渗漏情况。软质合金嵌体的挠度明显更大，近50%的嵌体因微渗漏出现染料渗透。平均而言，超硬质合金嵌体未出现挠度，仅25%的嵌体因微渗漏出现染料渗透。
