Direct composite resin restoration of an anterior tooth: effect of fiber-reinforced composite substructure.

The aim of the study was to determine the static load-bearing capacity of fractured incisal teeth restored with the conventional adhesive-composite technique or by using fiber reinforced composites (FRC). Upper incisal teeth were prepared by cutting the incisal part of the crown horizontally. Restorations were made by three techniques. Group A (control group) was restored by reattaching the original incisal edge to the tooth. Group B was restored using composite resin. Group C was restored with composite and FRC. Restored teeth were statically loaded until fracture. Results suggest that an incisally fractured tooth restored with a combination of composite resin and FRC-structure provide the highest load bearing capacity.
