Summary

The controlled three dimensional movement of anterior dentition during orthodontic treatment is a desire of every orthodontist. Maxillary en masse retraction with mini implants has been reported to provide absolute anchorage thus utilizing the complete extraction spaces thereby enhancing patient's esthetics. Power arm or anterior retraction hook permits the application of force close to a desired direction thereby warranting better anterior dentition control. Various heights of power arms and proposed centre of resistance for six maxillary anterior teeth have been estimated through finite element model and also from a very limited number of clinical studies. For a set of teeth, the determination of centre of resistance is complex in actual clinical scenario and response of force applied from certain level for better anterior dentition control requires sufficient clinical evidence suggestive of further clinical studies to endow orthodontists to hasten treatment due to less time consumption during finishing stage of orthodontic treatment.
