متن کاملIn vivo determination of the centres of resistance of maxillary anterior teeth subjected to retraction forces.
This study was designed to locate the centres of resistance of consolidated units of two, four, and six anterior teeth during retraction in two human subjects. Initial displacements of these units were separately measured when retraction forces were applied at different levels by means of a device for displacement measurement using magnetic sensors and magnets. By calculating the angle of rotat...
