RESUMO

The aim of this study was to cephalometrically investigate the stability of early open bite treatment. Nineteen children with a mean age of 9.78 years old that were treated for 12 months with a removable appliance with palatal crib associated with chincup were evaluated after 15 months (posttreatment period) and compared with a control group of 19 subjects with mean age of 9.10 years with the same malocclusion that was followed-up for the same period. The 76 lateral cephalograms were evaluated at T1 (after correction) and T2 (follow-up) and cephalometric variables were analyzed with statistical tests. The results did not show significant skeletal, soft tissues or maxillary dentoalveloar changes. Overall, treatment effects in the experimental group were maintained at T2 evaluation with an increase of 0.56mm in overbite. Overjet and maxillary incisors/molars position (vertical and sagittal) remained essentially unchanged during the study period. Only mandibular incisors showed some significant changes (labial inclination and protrusion) compared with the controls. Thus, it can be conclude that the early open bite treatment with a removable appliance and palatal crib associated with high-pull chincup therapy provided stability of 95%.
