Types and surface treatments of the fillers for resin composites

Abstract

Fillers play important roles for the improvement of mechanical properties of dental composite resins. Along with the fiber reinforcement, filler addition is the major reinforcement method of the composite materials. Then, most of industrial rubbers and resins are reinforced with fillers. In recent years, the fillers that impart various functions for the composite materials, have been developed. The surface modification of the fillers improve the compatibility and bonding property to the matrix, then the homogeneous high density filling and effective reinforcement are achieved. In this report, types and surface treatments of the fillers for resin composites are introduced.
