Retraction in orthodontics – a short review

Abstract

Aim-The aim of this review is to discuss about the retraction mechanism in orthodontics and to discuss in detail regarding the mechanism of action and their application in orthodontics. Objective-To list out the difference types of retraction mechanics used and their merits and demerits Background-The basic principle of retraction mechanism can be used in orthodontic space closure involving retracing the canine initially followed by remaining anterior teeth or entire anterior teeth can be retracted at once using intra or extra oral anchorage. They are broadly classified into friction and frictionless mechanism. Once the extraction of the teeth has been done, the orthodontist must choose the procedure to retract the teeth based on the demand of the case. This article provides the basic information of both the mechanics and their application in orthodontics. Reason-This review mainly done for better assessment and benefits of retraction mechanics and its appliances.
