| Riassunto: | 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. |
