Managing morphologically atypical impacted teeth orthodontically.

摘要

Impactions with severely dilacerated root is seldom reported, especially the maxillary incisor. It is probably because of the high clinical difficulty of bringing the dilacerated tooth into position: most patients probably would choose extraction with replacement by prosthesis instead. However, the philosophy seems to have changed recently. We report two cases one in which an impacted central incisor was brought in the arch by orthodontic traction. In the second case the impacted premolar was brought into the arch and was shaped as a mandibular canine for achieving a good functional occlusion.
