| Abstract | ||
| Aims: Heat cured acrylic resin is the material of choice for construction of complete dentures due to its desirable properties, although it has some disadvantages as its susceptibility to fracture. Several methods and materials are used to reinforce acrylic resin denture base. One of these methods is reinforcement by using fibers. In this study, visible light cure fiber frame work is used as reinforcement material and compared with reinforcement with glass fiber. Materials and methods: in this study, 128 samples were prepared for evaluation of transverse strength, impact strength, surface hardness, and residual monomer tests. The samples were divided into four groups 8 sample for each group; control group without reinforcement, reinforcement by using visible light cure fiber frame work, random glass fiber reinforcement, and mesh glass fiber reinforcement. Results: the results of this study showed that visible light cure fiber frame work system significantly increase the transverse strength and impact strength of the heat cured acrylic resin, and it didn’t affect the surface hardness and amount of residual monomer of heat cured acrylic resin. Conclusions: visible light cure fiber frame work system increase acrylic resin denture base resistance to fracture. | ||
