RESUMEN
The objective of this work is to report a restorative approach with composite resin applied in reverse in the aesthetic resolution of darkened anterior teeth. A 27-year-old female patient presented with the main complaint of dissatisfaction with the aesthetics of her smile due to dental darkening, a result of childhood trauma, without painful symptoms, pathological clinical signs or change in care. In the intraoral examination, a darkening of teeth 11 and 21 was observed, which radiographically showed thickening of the periodontal ligament, with disharmonious configuration of the marginal gingiva. From the clinical and radiographic characteristics, we opted for periodontal intervention for recovery and gingival levelling, followed by endodontic intervention and aesthetic restorative restoration. The restorative step was carried out sequentially by internal tooth bleaching, removal of dentin still pigmented after bleaching and enamel preservation. Soon after, it was restored in an alternative way and layered using a technique called reverse, using strips of polyethylene fiber over the dentin resin. The technique preserved the remaining enamel with the maintenance of the original remaining guides, proving to be a viable conservative alternative since of the diagnosis to the restorative conclusion in view of the longitudinal confirmation of the restorative efficacy after 1 year.
RESUMEN
ABSTRACT Permanent canines are essential for the preservation of the stomatognathic system, as they are part of the occlusal and aesthetic function and balance. During the normal development of occlusion, canines follow a long and complex trajectory until their eruption, that is, they are more likely to suffer disturbances during this process. Removal of the permanent canine should only be considered in extreme cases, where the canine itself is not susceptible to orthodontic traction. Orthodontic traction is the most indicated treatment due to the high morphofunctional and aesthetic value of the permanent canine. The aim of this study is to report a clinical case of traction surgery of the superior permanent canine included in the maxilla. A 13-year-old female patient attended the dental clinic at the Nilton Lins University accompanied by her guardian, referred by an orthodontistfor canine traction surgery. during the examIn the clinical analysis, tooth 13 was absent from the dental arch. The patient had a computed tomography scan, where it was possible to verify the actual position of the toothimpacted with the partially erupted crown on the alveolar ridge. After planning, surgery was performed to install an orthodontic button and adapt the ligature with a 0.30 mm wire. After the 10-month follow-up period, the presence of the tooth in arch, completely erupted, was observed, showing effectiveness in the proposed treatment. Therefore, the procedure for bonding the orthodontic device was performed satisfactorily without complications or intercurrences, making it possible to continue the orthodontic treatment. The patient remains under follow-up.
RESUMO Os caninos permanentes são essenciais para a preservação do sistema estomatognático, visto que, fazem parte da função e equilíbrio oclusal e estético. Durante o desenvolvimento normal da oclusão, os caninos seguem uma longa e complexa trajetória até seu irrompimento, ou seja, estão mais propensos a sofrerem distúrbios no decorrer desse processo. A extração do canino permanente só deve ser considerada em casos extremos, onde o próprio não se encontra suscetível à tração ortodôntica. O tracionamento ortodôntico é o tratamento mais indicado devido ao alto valor morfofuncional e estético do canino permanente. Sendo assim, o objetivo deste estudo é relatar um caso clínico de cirurgia de tracionamento de canino permanente superior incluso em maxila. Paciente de 13 anos, gênero feminino, compareceu a clínica odontológica da Universidade Nilton Lins acompanhado de seu responsável, encaminhada por um ortodontista para cirurgia de tracionamento de canino. Durante o exame clínico observou-se ausência do dente 13 na arcada dentária. A paciente apresentou a tomografia computadorizada, onde foi possível verificar o real posicionamento do dente impactado com a coroa parcialmente irrompida no rebordo alveolar. Após o planejamento, realizou-se a cirurgia destinada a instalação de botão ortodôntico e adaptação da amarrilha com fio 0,30 mm. Posteriormente ao período de acompanhamento de 10 meses, observou-se a presença do dente em arco, totalmente erupcionado, mostrando efetividade no tratamento proposto. Portando, o procedimento de colagem de dispositivo ortodôntico ocorreu de forma satisfatória sem complicações ou intercorrências, tornando possível a continuidade do tratamento ortodôntico. A paciente permanece em acompanhamento.
