Abstract
The study was performed in 30 subjects with class II/l and 30 subjects with class II/2 anomalies. The aim of the study was to assess the extent to which class II anomalies influenced individual craniometric and gnathometric dimensions as well as to determine whether there were any significant differences between the two subgroups. Craniometric dimensions were measured in each subject by means of standard measuring devices, while gnathometric analysis
was carried out on plaster casts of their dental arches. Statistical processing was performed on an IBM PC-AT computer, with a SPSS/PC program support. The study results indicated the maxillomandibular and craniofacial growth to follow a specific pattern as early as in the deciduous dentition in subjects with class II anomalies.Differences between class II subgroups manifested in the range of the following parameters: all transversal craniometric dimensions were greater in class II/2 , which was statistically significant in case of Eu-Eu dimension; height of the maxillary part o f the face was significantly greater in class II/2 ; horizontal incisal step was significantly greater in class II/l; although all transversal dimensions of dental arches were considerably greater in class II/2 , the differences were not statistically significant; the upper and lower dental arches were longer in class II/l and W 2 , respectively.
