A super-compact retained tooth is often responsible for rotation of a tooth round its axis; the retained tooth should be removed after preliminary x-ray examination of the site of abnormality. A great variety of etiopathological factors are responsible for the abnormality, and hence, the approaches to the choice of treatment are numerous. Rotation of teeth during orthodontic treatment involved stretching and strain of connective tissue fibers, which are not intended for rearrangement, and therefore the results are not stable. A long period of retention is needed for adaptation of tissues to a new position of the tooth.
