Distalization of maxillary molars using the speed system: a clinical and radiological evaluation

To show how a self-ligating system can provide bodily movement of maxillary molars without extraoral devices or lingual appliances, reducing the need for patient compliance. The control of these tooth movements has been clinically and radiologically substantiated.

The biomechanical principles, patient selection, and steps of the treatment are described. Some reference points are shown on the lateral cephalogram for superimposition, to evaluate the sagittal, vertical, and angular changes.

A number of cases have been treated with this technique, both distalization of maxillary first and second molars, with bodily movement and satisfactory anchorage management.

The described system works efficiently, all with only intraoral appliances, but the use of light and continuous forces to reach bodily distal movement without secondary effects is mandatory. The described system also produces the desired objectives with a short treatment time.
