Abstract

Background: The Multiloop Edgewise Archwire (MEAW) technique is a biomechanically efficient orthodontic method employed to correct various malocclusions, including posterior crossbite caused by inadequate transverse relationships between the maxillary and mandibular arches. MEAW archwire incorporate boot loops, providing enhanced flexibility and precise control of tooth movement. Case Report: A 21-year-old female came to the orthodontic clinic with severe maxillary and mandibular crowding, The patient presented with dentoskeletal Class I malocclusion characterized by a convex profile, clockwise rotation of the mandibular plane, retrognathic mandible, ectopic upper canines, anterior and posterior crossbite. The maxillary midline had shifted 2 mm to the right, and the mandibular midline had shifted 4 mm to the right. SNA: 80º, SNB: 76º, and Wit’s appraisal: 2.5 mm. as well as ectopic upper canines. Extraction of the upper and lower first premolars were performed. The combination of MBT 0.022” prescription and MEAW were used for this treatment. Active lacebacks were used to align ectopically erupted upper canines. MEAW was used to correct the posterior crossbite, resulting in improved interdigitation and ideal smile arch. Final Results: Post-treatment cephalometric analysis showed SNA: 80º, SNB: 77º, and Wit’s appraisal: 2.5 mm. Retention was maintained using removable Hawley retainers. Conclusion: MEAW arches are made of 0.016” × 0.022” steel wire, providing flexibility to the archwire and allowing for horizontal and vertical control of tooth positions. Precise construction of MEAW is essential to achieving optimal treatment outcomes and maintaining stable relationships. Keywords: MEAW, multiloop edgewise archwire, posterior crossbite

Abstract

Background: Class II subdivision malocclusions in skeletal class I, characterized with a class II relation on the left side and class I on the right side along with retroclined central incisors; Case: This case presenting a 13 years-old female patient class II subdivision in skeletal class I, with severe anterior and posterior crowding, anterior crossbite, right posterior scissor bite, upper midline shift to the right, SNA 80o, dental arch asymmetry,  SNB 77o, Wit’s appraisal 3 mm. Managing case: MBT.022 fixed appliances was used for this treatment, include extraction, alignment, levelling, protracting buccal segment. Resulting clockwise mandibular movement, anterior and posterior crowding, anterior crossbite, scissors bite was corrected, upper midline co-incide with lower midline, class I canine and molar, good interdigitation, and improved smile aesthetic. Treatment was completed in 31 months. Hawley retainer was use as a retention; Conclusion: This case report highlights a satisfying result of orthodontic treatment in Class II subdivision with extraction and protracting the posterior teeth and the importance of identifying the etiology in arch asymmetry cases. Keywords: class II subdivision, dental asymmetry, severe crowding
