<abstract xmlns="http://www.w3.org/1999/xhtml">

Non-extraction treatment was carried out for a growing Angle Class II division 1 patient. Because the patient demonstrated potential growth and all the third molars were congenitally missing, the extraction of the four premolars was ruled out.
A functional appliance (MGA) and cervical headgear were employed simultaneously in the first phase of treatment. The second phase was carried out by mechanotherapy.
As a result, adequate forward growth of the mandible was attained and all 28 teeth were kept in good relation with no root resorption and healthy periodontal tissue. A better improvement of the profile may have been attained had extraction treatment been performed; with non-extraction treatment, however, the amount of tooth movement could he minimized, and root resorption was not observed. The role of the functional appliance is also important for the success of non-extraction treatment in Class II patients.
