Dental Reshaping Using the Composite Resin Injection Technique After Dental Trauma and Orthodontic Treatment.

Abstract

Severe dental trauma can often result in tooth loss at an early age. Orthodontic space closure and reshaping of the teeth are a conservative treatment approach. The purpose of this paper is to present a fast and predictable way to reshape teeth using the composite resin injection technique. A 10-year-old female presented for orthodontic treatment with a Class II malocclusion, lateral open bite and loss of the permanent maxillary left central incisor due to trauma. The treatment plan involved mesialization of the maxillary left teeth and reshaping of the maxillary left canine and lateral incisor to the shape of the lateral and the central incisor, respectively. At the end of the orthodontic treatment, an impression was made and a transparent silicone index was fabricated based on the diagnostic wax-up. Through the index, flow composite resin was injected at the site to form the direct composite resin restorations.
