Abstract:
Introduction: High fracture resistance of prostheses are well accepted by both patients and dentists to have a proper restoration of the dentition. The research designated assess polymerization time effect distinct and complete temperatures on mechanical properties (denture base resin) of a high strength. The research purpose is to assess and compare the procedure used in polymerization distinct effect autoclave on the elastic modulus and transverse strength of a high strength acrylic resin to the conventional heat polymerizing. Methods: Rectangular sample of ninety-one polymarised high heat strength denture base resin were created. Polymerized sample done by hot water regarded as control group and the other groups were polymerized in autoclave at different temperatures and time lenghts. After deflasking of sample before procedure it was kept forty eight hours in water. Three parameters were used when conducting transverse strength test bending using calibrated universal testing machine with a load of 500 kg cell and a crosshead speed of 5 mm/min. One-way ANOVA was used in assessing transverse strength and elastic modulus data. And for comparison of the groups application of Tukey HSD trial has been seen appropriate (p <0.05). Results: Specimens that polymerized by autoclave at 130ºC for 20 and 30 minutes showed significantly better characteristics compared to the other groups. Conclusion: Upgrading of base resins transverse strength is required because the research indicated autoclave polymerization at 130°C for 20 and 30 minutes may be an alternative polymerization method.
