The Fan Expander is ideal for patients with cleft palates. Treat this appliance like a fixed expander, but consideration must be given to the activation rate predicated on the hinge location. Patients need to activate 3x per week. Four turns will produce 1mm of expander. Be aware that this appliance will have a significantly greater anterior expansion compared to mid to posterior expansion. Clean appliance 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. We recommend 3 minutes.
