This study aimed to report the treatment steps in a 26-year male patient, presented with a class II div 1 incisor relationship on a class II skeletal base with increased vertical proportions. The case was complicated by missing lower second premolars and retained lower second deciduous molars. Severe crowding was evident in the lower arch with mild crowding in the upper arch. The overbite and the overjet were increased. Scissor bite was evident in the left buccal segment. Treatment involved extraction of upper first premolars and lower second deciduous molars, utilizing moderate anchorage using a preadjusted edgewise fixed appliance (0.022’’ X 0.028”) with Roth prescription. Treatment duration was 20 months in total. The envelope of discrepancy specifies strict rules when camouflaging class II cases. The ability to retract incisors and the use of class II mechanics are within limited range to avoid damage to the periodontium. The current case report showed that the ability of the clinician to retract incisors using TADs could be carried out with high rate of success and safety. |
