For decades, the use of tooth colored restorative materials in posterior teeth was limited due to lack of appropriate material strength and resistance required during mastication. Amalgam and gold restorations were the accepted standard for posterior rehabilitation, with well reproduced contour and highly polished surfaces. Tarnish and corrosion were the major disadvantages of gold restorations, and amalgam restorations faced the problem of micro leakage and mercury toxicity. During the last decade, composite resins have been used much more frequently in the posterior region. Patients are now ...
For decades, the use of tooth colored restorative materials in posterior teeth was limited due to lack of appropriate material strength and resistance required during mastication. Amalgam and gold restorations were the accepted standard for posterior rehabilitation, with well reproduced contour and highly polished surfaces. Tarnish and corrosion were the major disadvantages of gold restorations, and amalgam restorations faced the problem of micro leakage and mercury toxicity. During the last decade, composite resins have been used much more frequently in the posterior region. Patients are now demanding non metallic restorations with natural appearance. Recent improvements in filler technology by manufacturers have allowed blends of both submicron particles (0.04µm) and small particles (0.1µm-1.0µm) to be incorporated into a composite formulation. These materials are classified as micro-hybrid composites. The mixture of smaller particles distinguishes micro hybrids from traditional hybrids and allows for a finer polish, along with improved handling.
