Spring Hawleys


Spring/Hawley: 3x3 design


The 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 position or over corrected. The appliance has acrylic on the labial bow and a mushroom shaped spring encased in acrylic on the lingual of the anterior teeth. This provides the flexibility and force needed to correct relapse or to treat minor orthodontic cases.
