The frequency of posterior resin composite restorations is increasing due to their aesthetic appeal and conservative nature. However, a balance between material properties and application techniques is crucial for successful restorations. High viscosity resin composites can improve properties but can also cause gaps and microleakage. Preheating resin composites is a technique used to improve flowability, reduce film thickness, and optimize polymerization, but its impact on mechanical properties and clinical performance remains unclear.
