title: [Effects of orthodontic treatment on the shape of upper dental arch of patients after surgical operation of cleft lip and palate].
abstract: Occlusal casts were measured and analysed in the following groups: orthodontic group(9 subjects treated orthodonticly after surgical operation of the cleft lip and palate), untreated group (10 subjects untreated orthodonticly after surgical operation), normal group(10 young subjects with normal occlusion). The results were that the upper dental arch length and width increased evidently (P < 0.01) in the orthodontic group and almost returned to normal; in contrast, the upper dental arch length and width were inhibited in the untreated group; there were significant differences among the normal occlusion group, the orthodontic group, and untreated group (P < 0.01). The results suggest that during the period of growth and development, the shape of the upper dental arch of the patients can be evidently improved by the orthodontic treatment after the surgical operation of cleft lip and palate.
