denture

The purpose of this study was to determine the effect of the addition of E-glass fiber (Chopped strands 3 mm size) with 1% and 1.5% weight concentration on the heat-polymerized acrylic resin denture base material to impact strength, transverse strength, and modulus of elasticity, and the correlation between them.

Broken acrylic resin dentures may be repaired with auto-polymerizing acrylic resin, heat-curing acrylic resin and recently, with visible light-cured resin.

As suggested by Lorton, Phillips [14] (1979), the dimensional changes that occur in acrylic resin dentures are complex, and many processing variables interact with one another simultaneously.

Fracture of acrylic resin denture base occurs frequently because of fatigue and chemical degradation of base material [2].

Acrylic resin denture contains methyl methacrylate (MMA) as a residual monomer.

The amount of residual monomer in an acrylic resin denture base, has been determined using various methods.

4 The release of residual monomer decreases with time, hence storing the acrylic resin denture in water for at least 24-48 hours before insertion is recommended.

The literature was reviewed by Cunningham7 relating to the determination of the tensile bond strength of acrylic resin denture teeth to the denture base material.

Techniques for bonding denture teeth to acrylic resin denture base remains empirical, with little consensus from the literature, among clinicians or among dental laboratories.
