The present study was conducted to compare the fracture resistance (compressive strength) of composite resin restorations with and without glass ceramic inserts. A total of 40 unrestored, noncarious, permanent, human mandibular molar teeth were selected. The teeth were divided into two groups. Group A: Teeth with class–I (pit) cavity preparations, restored with Prisma TPH composite resin. Group B: Teeth with class-I (pit) cavity preparations, restored with prisma TPH composite resin and Beta Quartz Glass Ceramic Inserts. The specimens were then subjected to a compressive axial load in a triaxial testing machine. The load required to fracture the restorations was noted for each specimen and calculated in kilograms. Results were derived and observations were made. Group B restorations had a much higher resistance to fracture as compared to Group A restorations When subjected to compressive load. The study showed that compressive strength was significantly increased when a composite resin restoration was done with glass ceramic inserts as compared to without glass ceramic inserts.
