Segmental retraction in Orthodontic Treatment of Patient with Ectopic Eruption of Maxillary Canine: A Case Report

Abstract

Abstract
Introduction: Ectopic canines are permanent teeth that develop outside of their normal position in the jaw and can be caused by genetic or environmental factors. And require orthodontic treatment to correct it. Objective: This case report involves orthodontic treatment using segmental retraction to correct ectopic maxillary canine. Case Report: A 13-year old girl complained that her canine tooth was above the other teeth in the right maxilla. The maxillary midline shifted to the right by 3 mm. Cephalometrics showed SNA 810, SNB 770, ANB 40, and overjet and overbite were normal. The molar and canine relation on the right side was class II, and the left side was class I. The patient was treated with segmental retraction to correct the position of the maxillary right canine with extraction of the maxillary right first premolar and extraction of the maxillary left premolar to fix the right shifted midline. After 19 months of orthodontic treatment, facial profile changes were achieved (convex to straight tendency), and ectopic maxillary right canine and shifted midline were corrected. Conclusion : Segmental retraction in orthodontic treatment of ectopic canine provides satisfactory results and quick correction for patients and improves occlusion function and aesthetics.
