Treating bimaxillary protrusion case with newly designed multiple variability (MV) loop: A Case Report

Abstract Proclination of anterior teeth is significantly found in developing malocclusions and affecting both aesthetics, function and stomatognathic system. In bimaxillary protrusions cases or crowding cases, extraction therapy is often necessary. Orthodontic treatment is initiated with the extraction of maxillary and mandibular first premolars to relieve the protrusions or crowding and achieve a harmonious occlusion. There are two ways to retract anterior teeth during extraction space closure: friction mechanics or frictionless mechanics. This case report describes 25 year old female patient with the class III skeletal and class I dental malocclusion with anterior proclination. Accordingly, the innovative treatment plan for the correction of anterior protrusion using multiple variability (MV) loops and completion of case with fixed orthodontic treatment using MBT 0.022” slot prescription to obtain a stable occlusal relationship, overjet and overbite. The case should be finished with a stable occlusion between the maxillary and mandibular arches with adequate width of attached gingiva.
