An innovative technique of denture repair by fibre-reinforced composite

Denture Repair is a very common practice encountered in everyday clinical Prosthodonitc practice. Fracture may be due to intraoral fatigue failure of acrylic resin or accidental dropping of denture outside the mouth. Anyone who dropped their dentures on to the floor or into the sink felt their heart skip a beat as it slipped out of their hands. Dentures are a significant investment of money, time and its damage can be a costly affair. It is well known that the ultimate purpose of repairing of a fractured denture is to restore its strength at least to the original one. It seems in practice that it is not the fact. The essence of successful denture repair relies on the phenomenon of adhesion. Strong bonding of inter surfaces improves the strength of the repaired unit and reduces the stress concentration. Unfortunately the reinforcements like metal wires, meshes and even some fibres do not bond to the parent resin. Fibre-Reinforced composite because of its superior flexural strength and capacity of its resinous matrix both to uniformly wet the fibres and to chemically bond to the parent resin makes it the most suitable material for long term repair.
