What materials are used in Hawley retainer fabrication?

High-quality Hawley retainers utilize medical-grade polymethyl methacrylate (PMMA) for the acrylic base plate, providing durability and biocompatibility.

The wire framework uses stainless steel (.028"-.032" gauge) for the labial bow and clasps, with some designs incorporating nickel-titanium for enhanced flexibility.

All materials must meet medical device standards with documented traceability and sterilization validation.
