Fixed Lower Expansion Appliance

The Fixed Lower Expansion Appliance is designed to achieve reliable, symmetrical arch development in the mandibular arch. Engineered for precision and durability, it provides steady lateral expansion while maintaining full control of tooth movement and arch coordination.

Featuring a center-mounted expansion screw and rigid stainless-steel framework, the appliance delivers gentle, consistent forces to broaden the lower arch. Its fixed design ensures optimal compliance and predictable results—ideal for cases requiring transverse development, crowding relief, or improved arch form.
