Abstract

Aims: The aim of this study was to evaluate the effect of PowerScopeTM (Class II Corrector) on skeletal, dental and oro-pharyngeal airway dimensions in class II malocclusion with retrusive mandible.
Materials and Methods: Twenty patients with age group of 11 to 14 were selected for this study. Experimental group underwent Power scope class II corrector therapy and control group, alignment of only upper arch respectively. Lateral cephalometric radiographs were taken in both experimental group and control group before and after 6 month of treatment. Sixteen measurements in that eight skeletal, five dental and three pharyngeal airway were assessed to know the effect of PowerScopeTM Class II corrector on skeletal, dental and pharyngeal airway
Results: PowerScopeTM Class II corrector after treatment showed significant change in SNB (P = 0.01*), ANB (P=0.001*), Inferior airway space (IAS) (P=0.006*), lower incisors position (P=0.0001*) and overjet (P=0.0001*) where as these values were insignificant on comparison with control group except for lower incisors position (P=0.001*) and overjet (P=0.0001*) indicating that PowerScopeTM corrects class II malocclusion mainly by dento alveolar changes not have significant effect on skeletal and oro-pharyngeal
airway.
Conclusion: Power ScopeTM (Class II corrector) corrects skeletal class II malocclusion mainly by dental changes and has insignificant effect on skeletal and oro-pharyngeal airway.

Keywords: Class II malocclusion, PowerScope TM Class II corrector, Oropharyngeal airway.
