Prostheses used temporarily are flexible based on function. Given the paucity of empirical knowledge flexural strength of temporary resins, choosing the right material for their manufacturing is challenging. Dentures have been reinforced with partial fibres both during the production process and during repairs. Polymer's fiber-rich phase in the denture base can either form a distinct structure or the reinforcing fibres can be dispersed equally throughout the material. In this work, the static three-point flexural strength and modulus of denture base polymer reinforced with various fibre reinforcements were determined. PMMA base material can currently be strengthened by adding fibre reinforcement. The creation of bar-type specimens complied with standard 27 of the American National Standards Institute and the American Dental Association. After being immersed in artificial saliva at 37°C for 10 days, the specimens were broken under 3-point loading with a crosshead speed of 0.75 mm/min in a universal testing machine. The highest breaking weights were expressed in Newton’s. The mean flexural strengths were measured in MPa (n = 10 per group). Results were compared using variance analysis and Duncan's multiple ranges testing (P.05). Impact strength of The Glass and Natural fibre (Jute, Sugarcane, Banana etc.) group with 1% and 0.5% composition respectively composition have the maximum value. This group shows the maximum value of flexural strength, compression strength and tensile strength. The findings imply that fibres that are impregnated or re-impregnated strengthen the denture base polymer more than fibres that are not impregnated. When compared to the same amount of fibre reinforcement placed on the compression side, the fibre reinforcement applied on the tensile side produced much higher values for flexural strength and flexural modulus.

As we know Teeth problems can be prominent as age increases also due to accident teeth breaks. Physical appearance can be greatly affected by teeth. So we need to test material which has better or similar properties to the natural teeth before restoring teeth with suitable material. Therefore, it is important to study the physical and mechanical properties of denture base material. Denture base material properties can be improved by adding various monomers and cross linking agent. Focus is on the increase of impact strength other mechanical properties of denture material. Different additives being used should be compatible with MMA (Methyl methacrylate) and polymerize to PMMA (Poly methyl methacrylate). Heat cure and variation in chemical composition can affect the mechanical properties. This paper presents the review of the work that has been done to improve the properties of denture base material and the problems being faced during the fabrication. The gap in the literatures available has been also discussed.
