title: Class II deep bite faces: one-phase or two-phase treatment?
abstract: Timing is the key for successful and stable results in Class II patients. Most low-angle patients are treated during the mixed dentition in two phases: orthopedics, then orthodontics. The vertical discrepancy differentiates the patient who will need extraction, the high-angle case, from those who should be treated through nonextraction, the low-angle case. Treatment of these latter patients necessitates expansion of the soft tissues. In the authors' practice, 70% of cases are treated nonextraction. This new concept for Class II treatment makes the Class II mechanics less traumatic because the occlusal correction requires less anchorage preparation. Most low-angle cases treated with two-phase treatment do not require surgical procedures. Orthodontics for tomorrow will necessitate more concept and less mechanics.
