The aim of the study is focused to: Identifying the dental, dental-alveolar and occlusion characteristics in the class II/2 subdivision and II/2 Angle subdivision and determining the differences between the two clinical forms. 
Matherial and method. The study regarding the dental, dental alveolar and dental occlusion characteristics was  carried out on plaster models of dental-alveolar arches in 62 patients orthodontically untreated, who were diagnosed with the class II/1 Angle malocclusion, class II/2 Angle, respectively, 40 females (64.5%) and 22 males (35.5%), with the age average of 10.4804 years and a standard deviation of 1.6939.
Results and discussion. The dental occlusion showed a large variability in all the three space directions, the sagittal rest position is significant for the class II/1 Angle subdivision, with a certain point, canine distal drift, thus confirming the opinion which became classic: the canine point is a more stable point than the molar point, justifying the clinician’s orientation according to this point. The statistically relevant overlap and the data we achieved pertain to the class II/2 subdivision.
Conclusions. Awareness of the dental arch characteristics, of dental occlusion help establishing therapeutic objectives and evaluating, short-, medium- and long-term post treatment results.
