Composites structure in dentistry and evolution of filler systems and their effects on properties of composites structure

Abstract

Composite material is a solid formed from two or more distinct phases (e.g., filler particles dispersed in a polymer matrix) that have been combined to produce properties superior to or intermediate to those of the individual constituents. The properties of composite material are dependent on the properties of the constituent phases forming the composite, their relative amounts, and the geometry of the dispersed phase (shape, size, distribution, and orientation) .The concept of multiphase composites provided opportunities for designing a large variety of materials with different combinations of properties that cannot be achieved by using a single metal, alloy, ceramic, or polymeric material.Most composites have been created to improve the properties whether mechanical, thermal, electrical, magnetic or optical properties of different materials to suit the required application. in this article different shapes of fillers will be discussed and how does it affect the properties of the composite structure. Moreover, the evolution of filler systems and their effects on properties of composites structure.
