The Fan type expander utilizes a hinged screw to widen the anterior while maintaining molar width. The appliance splits the mid-palatine suture, causing the transversal diameter of the maxillary anterior arch to enlarge, while leaving the posterior transversal diameter unchanged.

Treatment & Care
Activation of the screw is 1-2 times per week. Patients should wear 22 hours a day and clean daily with toothpaste to prevent the buildup of plaque and odor. Avoid Efferdent and other effervescent solutions, as it may erode components on the appliance. It is recommended to use products like DentaSoak or Retainer Splash.
