Sažetak
AIM: To assess the dentoalveolar compensatory mechanism in high-angle malocclusions. SUBJECTS AND METHOD: Dentoskeletal morphology was assessed in 77 subjects aged 13-18 years, with a high mandibular plane angle (m-go-ar>127.5° &plusmn ; ; 5.0°) by analyzing roentgenographic cephalograms. The subjects were divided into three groups based on the amount of overbite (OB): OB <0 mm = open bite ; OB = 0-4 mm = normal overbite ; OB > 4 mm deep bite. RESULTS: An open bite was observed in 49.4 per cent of subjects, a normal overbite in 41.6 per cent, and a deep bite in 9.1 per cent. There was no statistical significance in the degree of overbite between males and females. Among the overbite groups statistically significant differences were found for the skeletal variables anterior total face height (P=0.022) and anterior lower face height (P=0.036). For dentoalveolar variables statistically significant differences were found for ms-NL (P=0.015) and msa-NL (P=0.024), which represent posterior dentoalveolar height. In almost 50 per cent of the subjects with a high-angle malocclusion dentoalveolar compensation was noted which resulted from the relative decrease in maxillary posterior dentoalveolar heights.
