Aim: The aim of the study was to evaluate and compare sorption, solubility and microhardness of heat cure polymethylmethacrylate (PMMA) denture base resin and flexible (thermoplastic polyamide nylon) denture base resin.
Materials and Methods: Sorption, solubility and microhardness were assessed to determine compliance with ADA Specification no. 12. Results were assessed using statistical and observational analyses.
Result: All materials satisfied ADA requirements for sorption, solubility and microhardness. Heat cure (PMMA) showed more sorption, solubility and microhardness than flexible (thermoplastic polyamide nylon).
Conclusion: Flexible (thermoplastic polyamide nylon) resin absorbs less water, is less soluble and is more flexible than (PMMA).
