Orthodontic Space Closures with Canine Substitution for Bilateral Congenitally Missing Maxillary Lateral Incisors: A Case Report
Main Article Content
Abstract
Missing maxillary lateral incisors creates an esthetic and functional issue that necessitates unique orthodontic and restorative considerations. Consequently, various patient-specif ic factors, in particular patient satisfaction, should be meticulously evaluated prior to determining whether to close the space with canine substitution or open the space with tooth replacement. This case report describes successful space closure and canine repositioning used in the orthodontic treatment of a 25-year-old female patient with Class I malocclusion with bimaxillary dental protrusion and bilateral congenitally missing maxillary lateral incisors. Enhancing a patient’s appearance and functionality requires minimizing the use of a prosthesis and improving the patient’s facial profile, which includes the canine-like size, color, and shape of the maxillary first premolar. Orthodontic treatment was completed, with favorable results. The treatment time was 25 months. Although this case required some adjunctive procedures to improve the esthetics, the patient declined as she was very satisfied with the achieved results. After two years of follow-up, a stable occlusion with a satisfactory facial profile and functional excursion without interference was achieved. Functionality and esthetics can be improved by choosing this approach, which is less invasive as well as more economical.
