Abstract

Objective:The aim of this in vitro study was to compare some properties of polyamide(nylon) flexible and conventional heat cured acrylic resin denture base material. Material and Methods: 80 specimens were prepared according to the specific dimension for each test and allocated to two groups. Group (A) 40 specimens of conventional acrylic resin. Group (B) 40 specimens of polyamide denture base material. Results: Surface roughness and water sorption were tested for both groups. The data was collected and statistically analyzed. Conventional group showed significant higher roughness than polyamide group. Polyamide group showed non significant higher water sorption than conventional group. Conclusion: Polyamide denture base could be used as alternative material for conventional heat cured acrylic resin.
