Prevention of undesirable tooth movement in both arches is now possible. The use of small titanium bone screws has increased the envelope of orthodontic treatment, providing an alternative to orthognathic surgery (particularly in the vertical dimension) and allowing asymmetric tooth movement in three planes of space. Miniscrews provide the biomechanical advantage that allows more effective and efficient treatment with fewer auxiliaries and other appliances. Predicting resistance to tooth movement can minimize adverse responses, lead to more successful treatment of complicated problems, and...

Jackson's Triad consists of structural integrity, functional stability, and esthetic harmony. An ideal position of the incisors on its apical base in all three planes of space plays a vital role in achieving this balance. Deep bite (or excessive vertical overlap) is a common symptom associated with Class II malocclusions and can be corrected with various modalities including intrusion of upper and/or lower incisors, extrusion of posterior teeth, and flaring of anterior teeth. The intrusion of the upper and lower incisors is the most effective way of correcting the deep bite, as it moves their...
