To evaluate the use of modified power arm [Discopender 468] for efficient anterior teeth retraction - A clinical study
Journal Title: Al Ameen Journal of Medical Sciences - Year 2017, Vol 10, Issue 1
Abstract
Introduction: Many new bracket prescriptions and Techniques have been developed and modified as treatment mechanics progress to create force system that can work efficiently and shorten the orthodontic treatment period. Aim of this study was to evaluate the use of modified power arm [Discopender 468] for efficient anterior Teeth retraction, to determine anchorage loss and upper incisor changes after space closure. Material & Method: Ten patients of class II division1were selected to need maxillary first premolars was extracted and the retraction of anterior teeth was carried out segmentally by using discopender468 which applies variable force with respect to height of power arm. To prevent anchor loss during anterior retraction we have placed the mini implant screw mesial to 1stmolar bilaterally in maxillary arch. Pre and post lateral cephalograms were taken to determine the anchorage loss and upper incisor changes. Result and Conclusion: Anterior retraction carried out by a new design of discopender 468 and minim plant brings out controlled bodily tooth movement and also has variable force vectors, which is one of the variable method to use for retraction in Straight Wire Appliance in day to day orthodontic practices and also has advantage over conventional retraction mechanics.
