Effects of Microstructure on Compressive Fatigue of Composite Restorative Materials
Particulate reinforced polymer matrix composites are widely used in dentistry as esthetic restorative materials. Although the normally measured mechanical and physical properties of this class of materials approach the properties of dental amalgam (1) composite restorative materials exhibit limited durability in clinical service. Compared to amalgam restorations, composites undergo loss of material through wear processes and exhibit breakdown at the interfacial region between the restoration and tooth structure.
