Phase 1 Hybrid Retainer
Designed by Dr. Kevin L. Theroux DDS, MS, the Theroux retainer ensures arch width and tooth position are preserved post-Phase I treatment. It accommodates erupting adult teeth and shedding deciduous ones. Ideal for patients with short clinical crowns, this appliance wraps around the incisors, stays 2mm from the gingival margin, and encases the molars. Its rigidity excels in maintaining the arch form after expansion.
