Abstract
Objective: We present a case in which a prefabricated functional appliance was used for two years, and evaluate its mechanism of action, indications for treatment, and a case requiring attention. Cases: The patient was a 9-year 9-month-old boy. This patient showed skeletal maxillary protrusion with excessive over jet and overbite and crowding in the maxilla-mandibular anterior tooth area. Clinical examination and results: This patient showed correction of over jet, overbite, molar relationship, cephalographic ∠ ANB, and maxillary anterior tooth axis. However, this patient presented slight correction of ∠ SNB due to mandibular clockwise rotation. Furthermore, marked labial tipping movement of the mandibular anterior tooth axis was noted. Conclusion: Regarding this appliance, greater effects can be achieved through understanding the disadvantages of the appliance and its application based on appropriate diagnosis of treatment cases.
