The main goal of any dental prosthetic treatment is not only replacing missing natural teeth but also protecting the remaining natural ones.1
Nowadays, provisional restoration has become essential in the success of any fixed partial denture procedure, as it should provide both pulpal and periodontal protection, good marginal integrity, positional stability, sufficient durability to withstand the forces of mastication, esthetics, as wall as, to obtain certain diagnostic informations.1,2
Various materials based on acrylic and composite resins are available for fabrication of provisional crowns and fixed partial dentures, they are either heat cured, light cured or self cured .3
The fracture strength of provisional materials is important, particularly when the patient must use the provisional restoration for an extended period or when the patient exhibits parafunctional habits. Unfortunately provisional materials generally exhibited low fracture strength. 4-6
Therefore Interim restorations with improved physical properties are required.
Several attempts have been reported to reinforce provisional fixed partial denture, including the use of metal wire, a lingual cast metal reinforcement, a processed acrylic resin provisional restoration and different types of reinforcing fibers such as carbon, aramide, polyethylene and glass.
