Great Lakes recommends 2mm Biocryl for fabricating Hawley style retainers on the upper arch, and 3mm Biocryl for the lower arch. Biocryl comes in various colors, shapes, and patterns that appeal to most patients.
Hawley retainers with pontics, expansion screws, springs, and anterior bite plates can also be fabricated with this material. See the Videos & Techniques on this page for further instructions.
