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 provide efficient care in less time. Teeth can be moved directly (en masse without anchorage loss) to their final positions. Improved techniques and information over the last two decades have enabled clinicians to obtain more ideal tooth positioning.
