Sažetak
The aim of this study was to determine the mean values and standard deviations of variables that evaluate the inclination and position of incisors in patients with Angle Class II/1 and Class II/2; to determine the statistical significance between investigated variables among groups; and to point out the most significant variable for evaluating the difference between these Angle Classes. The sample consisted of 38 radiographs of patients with Angle Class II/1, and 35 radiographs of patients with Class II/2. The analysis comprised 10 variables: 1 : sp-pm, 1 : m-go, 1 : 1, Is : n-ss, Ii : n-sm, 1 : n-s, Is : A-Pog, Ii : A-Pog , 1 : n-A (°), 1: n-B (°). Means and standard deviations were determined for all variables, and Student t-test were performed to test the differences between investigated groups. It could be concluded that there is significant difference between all investigated variables between subjects with Angle Class II/1 and Class II/2 except for the variable Ii:n-sm. The main dentoalveolar characteristics of subjects with Angle Class II/1 are protrusion of upper and lower incisors in relation to their skeletal base, and protrusion of upper incisors in relation to the anterior cranial base, while Class II/2 patients exhibited retrusion of upper incisors in relation to the basal bone and to the anterior cranial base.
