Fibers In Dentistry: An Update

The fiber reinforced composite has become an effective material of choice within restorative dentistry. The rationale behind the usage of fiber reinforcement is partly to internally strengthen the structurally compromised tooth and partly to prevent the occurrence of fractures. The efficacy of fiber reinforcement is dependent on several factors including the resins used the length of the fibers the orientation of fibers the position of the fibers the adhesion of the fibers to the polymer matrix and the impregnation of the fibers into the resin. The reinforcing effect of the fiber fillers is based on stress transfer from the polymer matrix to the fibers. Utilizing different types of fibers with various orientations and lengths is quite a good idea to do restorations with high strength and fracture toughness.
