Pressure absorbability between polymethyl-methacrylate and thermoplastic nylon denture base materials

摘要

The purpose of this present study was to evaluate the pressure absorbability between polymethyl-methacrylate (PMMA) and thermoplastic nylon denture base materials. Mandibular first molar acrylic denture tooth (Bioeco) embedded on 15x15x3 mm3 thermoplastic nylon (TCS and Biotone) and PMMA (Huge) denture base materials were evaluated (n=6). A 100N force was applied on the specimen using universal testing machine and the pressure absorbed by the specimen was observed using pressure transducer. Both data were statistically analysed using 1- way ANOVA followed by Tukey HSD post-hoc test (P<.05). The results showed that the pressure absorbability of PMMA, TCS and Biotone were significantly different (P<.001). PMMA has the lowest pressure absorbability compared to thermoplastic nylon denture base materials.
