Maxillary canine substitution for the severely resorbed root of central incisor: 12-year follow-up

Ectopically erupting maxillary canines can cause problems that necessitate surgical, orthodontic, and restorative treatment. When a canine eruption disturbance causes resorption and requires subsequent extraction of the affected teeth, the resulting spaces are candidates for orthodontic repositioning and recontouring of the remaining teeth. To achieve successful results, the clinician must have a proper knowledge of tooth anatomy, root angulation, gingival margin position, restorative techniques, and occlusion. A collaborative effort from the pediatric dentist, orthodontist, and surgeon is required to produce an esthetic and functional result. This case report describes the substitution of maxillary canines for both the left central and right lateral incisors and substitution of the maxillary right lateral incisor for the maxillary right central incisor.
