Non-Surgical Orthodontic/Orthopedic Treatment of a Young Adult Class III Patient

ABSTRACT

Objective: To report and evaluate the outcomes of nonsurgical orthodontic treatment of a young adult female patient with Class III malocclusion and hyperdivergent growth pattern. Material and Methods: The 15-year-old patient with moderate skeletal Class III malocclusion and hyperdivergent growth pattern was treated by the Authors (M K-M and AK). The treatment started after growth completion (CS6 in cervical vertebral maturation) and consisted of the combined use of a face mask, Haas-type expansion appliance, a lower fixed appliance and Class III elastics for the first phase of treatment followed by full fixed appliance. Lateral cephalometric radiographs were taken at the beginning (T1) and at the end (T2) of treatment. Selected cephalometric analyses and superimpositions were used to evaluate dental, skeletal and facial changes with treatment. The patient was followed for 7 years to document the stability of non-surgical orthodontic/orthopedic treatment.

Results: Patient treatment improved the skeletal relationship, dental relationship and visible enhancement in the appearance of the midface, lip profile and the position of the chin. Improvement in the anteroposterior skeletal relationship was demonstrated by an improvement in the ANB angle and Wits appraisal. The vertical dimension was maintained with an improvement of the overbite. Upper and lower incisors were uprighted to a more correct position. Treatment results were stable for 7 years.

Conclusion: Successful non-surgical orthodontic treatment can be achieved in young adult Class III patient with a hyperdivergent growth pattern with a combination of orthopedic and fixed appliances. It can be an alternative treatment for patients who decline the option of surgical treatment.
