Removable expansion plate improves transversal dental dimensions of maxilla, Study says
Recent research has observed that a removable expansion plate is successful in improving the transversal dental dimensions of the maxilla, as published in the European Journal of Orthodontics.
The authors, A-S Van de Velde and associates from the Department of Oral Health Sciences-Orthodontics, KU Leuven & Dentistry, University Hospitals Leuven, Leuven, Belgium conducted a prospective cohort study wherein they investigated the short term effects of interceptive orthodontic treatment with a removable expansion plate, evaluating the changes in occlusion in all its dimensions: transversal, sagittal and vertical.
A total of 226 patients treated with a removable expansion plate (slow maxillary expansion, SME) by orthodontic residents were included. The patients had a mean age of 8.5 years at the start of the treatment.
The mean treatment time was 6.9 months. Transversal measurements (intercanine and intermolar width) and occlusal characteristics (molar occlusion, overjet, overbite and functional shift) were collected before (T0) and after active treatment (T1).
