Fan Exspider Expansion Orthodontic Model
Patients with a birth defect known as a cleft palate require expansion of the anterior portion of the maxillary arch. The Fan Expider addresses this need by placing a hinged device on the posterior segment of the appliance and a expansion screw on the anterior segment. This causes the appliance to open in a “fan” motion with all of the lateral expansion in the anterior region.
