The En Masse and the Sequential Retraction Procedures

Abstract

In this article, the authors discuss two preeminent notions in orthodontics; those are the approaches of “En Masse Retraction” and “Sequential Retraction” in orthodontic cases. The “Sequential Retraction” is identified by retraction of canines firstly, forming one group of retracted canine and posterior teeth in the respective side, then retraction of the incisors. Besides, the approach of “En Masse Retraction” is identified by retraction of the six anterior teeth “as one group”. Sequential Retraction is called “two-phased retraction”, whereas “En Masse Retraction” termed as “one-phased retraction”. Sequential Retraction has been justified for its characteristic of upholding anchorage, while En Masse Retraction is beneficial in keeping the alignment of the anterior teeth during treatment
