RECENT ADVANCES IN COMPOSITES

A composite material is a product which consists of at least two distinct phases normally formed by blending together components having different structures and properties.The aim of restorative and esthetic dentistry is to replace lost or damaged structures with artificial materials that possess physical ,biological and functional properties similar to that of the natural teeth. This constant desire of dental profession to achieve a natural appearance, has led to development of various tooth coloured material, one among them being dental composites.¹ Resin-based composites have been successfully used in dentistry for many years and widely replaced amalgam as a posterior restoration. There are many reasons for this relatively rapid and significant change in restorative dentistry.
