Abstract	Polymerization shrinkage of resin-based composites remains a major concern in restorative dentistry because it may result in cuspal deflection, marginal gap formation, postoperative sensitivity, and microleakage. Advances in restorative materials such as microhybrid and nanohybrid composites have been introduced to minimize these adverse effects and improve marginal integrity.
Keywords	Cuspal deflection, microleakage, nanohybrid composite, polymerization shrinkage, MOD restoration, composite resin.
