Impact strength and fracture morphology of denture acrylic resins.

Statement Of Problem: Microwave-polymerization cycles may affect the impact strength and fracture morphology of denture base acrylic resin, and the microstructural effects of these processes have not been fully determined.

Purpose: This study evaluated the impact strength and fracture morphology of denture base acrylic resins processed by microwave energy and hot water bath.

Material And Methods: Twenty specimens measuring 65 x 10 x 2.
