Description
Arjun S and five colleagues compare denture base plastics made with different curing cycles. Dentures of polymethyl methacrylate face chewing stress inside the mouth and knocks outside it. Over time they crack and break, so stronger mixes and better curing both matter.
The lab study tested standard resin and high-impact resin, each cured on short and long heat cycles. Samples faced a three-point bend test for flexural strength and a notched Charpy test for impact strength. High-impact resin on the short cycle scored best on both measures. Standard resin also bent stronger after short curing, though its impact strength barely changed. The authors favor high-impact resin with short cycles.
