摘要: The use of adhesive resin composites for restoration Class V lesions often results in cervical marginal gap formation due to polymerization contraction. In this laboratory study, flexible linings applied between the bonding agent and bulk restorative appeared preserve integrity restorations during curing. Measurements contraction stress showed 20 50% relief various intermediate materials. Apparently, reduction total stiffness by application an layer can render sufficiently compensate that part would otherwise exceed bond strength.
