Sažetak

Dento-alveolar adaptation in subjects with mandibular prognathism is the reason of clinical findings of almost normal occlusal and dental relationships between maxilla and mandible, despite of sagittal jaw. The purpose of this study was to obtain: the most significant characteristics of patients with mandibular prognathism; to find which variables quantitatively describe dento-alveolar adaptation and which of the used parameters have the most influence on achieving the normal relationship between the upper and the lower jaw as well to find the correlation between defining cephalometric variables. A sample of 62 cephalograms of subjects with mandibular prognathism both sexes, average age 18.7 years were analyzed. Cephalograms of eugnathic subjects were served as control. Eight dento-alveolar variables were observed: SNA, SNB, ANB, GIBG, DIBD, IIK, LA and LB, and statistical analysis were performed. As compared to eugnatic patients, all variables were significantly different, except SNA. The most signifficant decrease was found in the variable presenting the inclination of lower incisors in the relation to the mandibular base (DIBD), meaning that patients with mandibular prognathism have more retruded lower incisors which is a result of dento-alveolar adaptation. Significant correlations were found between variables SNB and ANB, DIBD and LB, and ANB and LB.
