Abstract

An adult female patient presented with a pronounced maxillary dental midline deviation and localized crowding in the upper right quadrant, particularly involving the canine and second molar. The maxillary right canine was buccally erupted and overlapped the lateral incisor and first premolar due to insufficient arch space and unfavorable root proximity. The mandibular arch exhibited mild anterior crowding with a flat curve of Spee. Orthodontic treatment was initiated using preadjusted fixed appliances. Extraction of the maxillary right third molar was performed to allow immediate sequential distalization of the maxillary right molars. A bypassed-canine main archwire in combination with a temporary anchorage device (TAD) placed distal to the apex of the maxillary right first molar facilitated efficient molar distalization and buccal expansion. Correction of the maxillary dental midline was achieved through total arch distalization using an additional TAD placed in the upper left posterior region. Guided eruption of the maxillary right canine was accomplished using an improved super-elastic nickel–titanium alloy wire (ISW), which delivered light, continuous forces conducive to physiological tooth movement and favorable periodontal adaptation. The treatment resulted in proper tooth alignment and inclination, stable intercuspation, optimal overjet and overbite, and bilateral Class I canine and molar relationships. A four-year post-treatment follow-up demonstrated stable occlusion and an improved facial soft tissue profile, confirming the long-term effectiveness of the treatment approach.
