A bond strength of _____ MPa is an estimated requirement to prevent marginal gaps as a result of polymerization shrinkage during placement of composite restorations.

Question

Quizplus · Accepted Answer

A bond strength of 20 MPa is the estimated requirement for preventing marginal gaps caused by polymerization shrinkage during placement of composite restorations. This bond strength is necessary to ensure sufficient adhesion between the composite and the tooth structure, reducing the risk of marginal gaps and subsequent microleakage, which could lead to secondary caries or restoration failure. Lower bond strengths increase the risk of marginal gaps, which compromise the integrity of the restoration over time.
