Adhesion failure of resilient lining materials to poly(methyl methacrylate) denture base material is a problem that is encountered clinically. This study compared the shear bond strength of some of the commercially available resilient lining materials to various denture base resins. Significant differences were observed in the shear strengths between the selected resilient liners and the denture base materials. Coe Super Soft specimens failed principally cohesively. Molloplast-B specimens always failed cohesively and Novus specimens always failed adhesively. Therefore, it was apparent that the bond strengths of Molloplast-B and Coe Super Soft specimens exceeded the cohesive strength. The bond strength of Novus was dependent on the denture base material and was greatest with Lucitone 199 and TS 1195.
弹性衬里材料与聚甲基丙烯酸甲酯义齿基托材料之间的粘结失败是临床上遇到的一个问题。本研究比较了一些市售弹性衬里材料与各种义齿基托树脂的剪切粘结强度。在所选用的弹性衬里材料和义齿基托材料之间观察到了显著的剪切强度差异。Coe Super Soft样本主要发生内聚破坏。Molloplast - B样本总是发生内聚破坏，而Novus样本总是发生粘结破坏。因此，很明显Molloplast - B和Coe Super Soft样本的粘结强度超过了内聚强度。Novus的粘结强度取决于义齿基托材料，与Lucitone 199和TS 1195结合时粘结强度最大。
