Hawley retainers are removable orthodontic appliances commonly used for retention and limited treatment applications. They are fabricated with a custom acrylic base and a contoured labial bow designed to maintain or refine tooth positioning following active orthodontic care. Depending on the treatment objectives, Hawley retainers may be designed for passive retention or adjusted to allow minor tooth movement with or without springs, as well as through traditional or digital tooth reset. Their adaptability, durability, and long-term serviceability make Hawley retainers a reliable option for both Phase 1 treatment and post-treatment retention.
