title: Predictive value of morphologic parameters for successful correction of Class II Division 2 malocclusion.
abstract: The aim of this study was to assess the predictive value of pretreatment cephalometric parameters and apical base size for successful correction of Angle Class II Division 2 malocclusion. Pretreatment lateral cephalograms and pretreatment and posttreatment study casts of 96 subjects with Class II Division 2 malocclusions were examined to obtain 23 cephalometric parameters and to measure the size of the apical bases. Success of occlusal correction was evaluated as the percentage of change of peer assessment rating scores during treatment; percentage of change was the dependent variable in multivariate statistical analyses used to test the predictive value of the assessed parameters. Cephalometric parameters of pretreatment craniofacial morphology were insignificant as predictors of successful orthodontic correction of the malocclusions. Maxillary apical base size was the strongest predictor of occlusal correction and might serve as a valuable diagnostic predictor of successful treatment outcome.
