Orthodontic-surgical management of an unusual dilacerated maxillary incisor

Abstract

Orthodontic traction of an impacted dilacerated maxillary central incisor is clinically challenging and often results in a long treatment duration. A case of an unusual dilacerated central incisor with a 90° crown-root angulation and palatally displaced crown is presented herein. Using a single stage open window exposure of the crown on the palatal aspect with light orthodontic traction force, the impacted dilacerated central incisor crown was successfully positioned in alignment with the contralateral incisor.

Multidisciplinary Management of A Nasally Displaced Dilacerated Tooth Following Early Childhood Dental Trauma: A Case Report

“…However, there are possible limitations to this process namely, extended treatment time because of a low orthodontic force of traction needed, the root tip may perforate through the labial cortex because of rotation of the tooth in its fulcrum, the tooth may undergo necrosis because of compression of the neuromuscular bundle and forms discharging sinus that may require root amputation. These limitations should be explained to patients and parents before the treatment [13], [24], [25].…”

Tracionamento de canino mandibular impactado após cirurgia de odontoma para posterior correção da maloclusão: relato de caso

“…Se o elemento dental estiver em posição de erupção favorável (Face incisal da coroa voltada para o rebordo alveolar) e com o ápice radicular aberto, haverá grandes chances de erupção espontânea, mesmo diante de uma dilaceração radicular (17) . Já outros autores relataram que o canino impactado localizado por vestibular está associado mais frequentemente à falta de espaço no arco dentário (83%), enquanto o canino impactado localizado por lingual, em 85% dos casos não está associado ao apinhamento (18) .…”
