Abstract:
Objective:To compare the properties of three kinds of denture base materials treated and untreated by hydraulic pressure cooker. Methods: The impact strength, flexural strength, flexural elastic modulus and color difference roughness of three denture base materials, Kunshan Rijin(KR),GC UNIFAST Trad(GC), Shanghai Zhangjiang(SZ), were measured in vitro. All results were statistically analyzed with SPSS software to have ANOVA and Tamhane's T2 tests, α=0.05. Results: Comparison of the same materials between the treated materials and the untreated materials by hydraulic pressure cooker: there were significant statistical differences of impact strength for all the materials. There were significant statistical differences of color difference for KR and SZ. Comparison of the three materials: impact strength, GC>SZ>KR;flexural strength, KR>SZ>GC;flexural elastic modulus, KR>SZ>GC;roughness, GC>KR>SZ. Conclusion: The properties of denture base materials treated by hydraulic pressure cooker are good.
