Multidisciplinary Treatment of Severe Upper Incisor Root Resorption Secondary to Transposed Canine.

OBJECTIVE: Tooth transposition is a rare dental anomaly that could lead to undesirable side effects on other teeth. This case report aims to describe the multidisciplinary treatment of a patient with a severely resorbed permanent maxillary central incisor due to transposition with the permanent canine.

CLINICAL CONSIDERATIONS: A girl aged 13 years and 7 months with a chief complaint of a pink spot on her maxillary left incisor with a slightly erupted tooth above it was referred to our clinic. Her left maxillary canine was transposed to her left central incisor site. The left canine was impacted and had caused severe resorption of the left central incisor root. Her maxillary left canine was substituted for the central incisor after the compulsory extraction of her left central incisor. The canine was prosthetically restored after orthodontic treatment. The results were stable 1 year after treatment had been completed.

CONCLUSIONS: Orthodontic treatment in coordination with other dental specialties like prosthodontics, periodontology and oral and maxillofacial surgery can provide functional and esthetic outcome in cases of severely transposed canines.

CLINICAL SIGNIFICANCE: This is a rare case of transposition that shows the significant root resorption on the maxillary central incisor due to the ectopic eruption of the canine. Canine substitution for the central incisor was chosen as a treatment plan instead of placing an implant. An esthetic smile and a functional occlusion were established at the end of the treatment.
