Recent Advances in Composite Resins- A Review

The introduction of resin-based dental materials around the mid of the last century was a revolution in restorative dentistry. The early formulations were characterised by numerous problems like improper handling characteristics, polymerization shrinkage, improper marginal adaptation, inappropriate proximal contact and most importantly secondary caries and inadequate wear resistance. The need to improve shrinkage properties and wear resistance is obvious for dental composites and a vast number of attempts have been made to accomplish these aims. Based on recent clinical information, it appears that major successes have been achieved in reaching the goal. This article discusses the advances in resin restorative materials.
