Angle Class II, division 1 malocclusion.

A complex Class II, Division 1 mutilated dentition is presented. The change from an Angle Class II to an Angle Class I occlusion was made by movement of the teeth along the occlusal plane. To achieve the desired pretreatment goals, the vertical dimension had to be managed. Directional force mechanotherapy can provide the clinician with an efficient, predictable force system to achieve both vertical and horizontal control.
