When Class III non-surgery is planned for the patients, upper and lower incisor positions and inclinations must be decided to indicate types of tooth movement. Subsequently, appropriate biomechanics is established. For the upper incisor, protraction and extrusion are the most often movements while retraction and intrusion are for the lower incisors. Many times, when mandibular rotations are favorable for reducing the concavity of the face, molar extrusion should be introduced. In this presentation, an innovative biomechanics system of upper incisor protraction with extrusion, lower incisor retraction with intrusion, and molar extrusion will be presented. Samples of cases will be introduced in details of clinical applications along with their biomechanics.
