Abstract :

Anterior open bite treatment is considered to be a complex treatment in the field of orthodontics. Orthognathic surgery is often the treatment of choice for these types of malocclusions and prognosis of the results are still questionable. With the introduction of Multiloop edgewise archwire therapy, treatment of open bite has started showing efficient results. Moreover, MEAW is versatile as it is capable of correcting various malocclusions as well such as Class II, Class III, deep overbite, and malocclusions with marked midline deviations. Since the advent of the MEAW, its treatment modality has been used worldwide and numerous reports of successful results have been published. Some orthodontists have described the MEAW technique as “magical” or “unbelievable,” but it certainly is not. The diagnosis and treatment plan must be correct and construction of the MEAW must be precise to deliver the necessary forces to move the teeth to an optimal, stable relationship.Hence this article aims to review the multiloop edge wise arch wire technique in detail along with its biomechanics.
