Composite restorative materials represent a class of unique modern biomaterials since they replace biological tissue in both appearance and function. The early formulations were characterized by problems such as polymerization shrinkage, improper marginal adaptation, inappropriate proximal contact, discoloration or staining and also secondary caries. The need to improve said properties and achieve adequate contact is necessary for dental composites and numerous attempts have been made to accomplish these aims. Newer generation composites have been produced in order to protect the healthy tooth structure, to reduce microleakage and secondary caries formation, increase fracture toughness and to reduce marginal pigmentation and postoperative sensitivity together with developments in technology. This article discusses the advances in resin restorative materials.
