Abstract
|
|
|
|
This is a case report of a 12.5-year-old girl who presented with moderate to severe anterior dental crowding and rotations. Treatment involved no extraction, but expansion of both the maxillary and the mandibular arches. Maxillary expansion was assisted by rapid palatal expansion despite the fact that this patient did not present with posterior crossbite. Crowding and rotations in both arches were corrected and good occlusal function and improved facial esthetic were achieved, with acceptable overbite and overjet. The application of rapid maxillary expansion in cases with no posterior crossbite, which has increased in recent years, calls for re-evaluation of the diagnostic basis and indications for the use of this technique.
