Abstract

Introduction: There has been a long discussion in orthodontics about the sliding and loop mechanics as the preferred method of retraction of anterior teeth in maxillary first premolar extraction cases. But no study has compared sliding and loop mechanics with indirect anchorage for enmasse retraction.this study aims to compare sliding and loop mechanics with indirect anchorage while doing enmasse retraction of anterior six maxillary teeth.
Materials and Methods: 11 patients were treated with sliding and loop mechanics each and enmasse retraction was done after maxillary first premolar extraction and using indirect anchorage with the help of miniscrews.
Results: Sliding mechanics is found to be better than loop mechanics in anterior retraction and reducing proclination with faster space closure. Loop mechanics was found to be better in torque control and preventing bite deepening during retraction.
Conclusion: Both mechanics have their own advantages and disadvantages and hence should be used as per the requirement of individual cases.
Keywords: - Sliding, loop, friction, frictionless, indirect anchorage, retraction.
