Spring HawleysThe Spring Hawley combines the Spring Retainer's anterior with the Hawley's posterior. This design provides maximum anchorage for the alignment of the anterior teeth. Anterior teeth that are not in proper alignment are reset into an ideal or slightly over-corrected position. The appliance has acrylic on the labial bow and a mushroom-shaped lingual spring.
