Comparative analysis of pendulum appliance (PA) and the distal screw appliance (DS) in Class II malocclusion patients
Navid Wani, Uzma Nazir, Umer Bashir

Background: Recent developments in mechanotherapy & changes in concepts have reduced the need for extraction in several types of discrepancies. The present study compared pendulum appliance (PA) and the distal screw appliance (DS) in Class II patients. Materials & Methods: The present study was conducted on 92 patients of class II malocclusion of both genders. Patients were divided into 2 groups of 46 each. Group I patients were treated with the pendulum and group II patients were treated with distal screw appliance. The mean distalization time was assessed. Lateral cephalograms were obtained before treatment and at the end of distalization. Results: Out of 92 patients, males were 50 and females were 42. Group I patients were treated with the pendulum and group II patients were treated with distal screw appliance. Each group had 46 patients. The mean distalization time in group I was 7.2 months and I group II was 8.6 months. The difference was non- significant (P> 0.05). Conclusion: Authors found that both pendulum appliance and distal screw appliance was equally effective in distalizing molar in class II malocclusion patients. Key words: Class II malocclusion, Distal screw appliance, Pendulum appliance
