Dental Expanders, Fixed Appliances

Frozat (Lower W-Arch)

The Forzat Lower W-Arch appliance is a straightforward yet effective orthodontic tool for expanding the lower dental arch. Constructed from durable .036 wire, the appliance features lingual wires that extend to the anterior teeth, allowing for controlled expansion. Loops can be added to the design for additional adjustments, providing flexibility in treatment. The wire is securely laser welded to bands, ensuring stability throughout the expansion process. This appliance offers a reliable solution for achieving optimal lower arch expansion with precision.

Treatment & Care

There are two ways to activate the Frozat before placing it in the mouth. Ricketts et al. (1979) originally suggested that operators activate the appliance with three-pronged pliers to incorporate expansion and molar-rotating force. Another method proposed by Kholoki (1995) employs an arch form chosen from a pentamorphic chart that serves as a pattern for regulating the Frozat.

This appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.

More About Frozat (Lower W-Arch)

Also Known As:
Lower W-arch expander, Frozat W-arch
Who Made Me:

Dr. George B. Crozat of New Orleans invented the Crozat appliance in the 1920s. The Crozat appliance is a removable, precious-metal device that’s used to correct malocclusions and dentofacial deformities. The Frozat Lower W-Arch was developed as a specialized version of the W-Arch for lower arch expansion. This design, originating in the late 20th century, allows for controlled expansion of the lower dental arch in cases where both upper and lower arches need expansion or when addressing crowding in the mandibular teeth.
