A healthy 8-year-old male presented with an unerupted upper right central incisor (UR1) associated with two supernumerary teeth. Despite extraction of the supernumerary teeth, a gold chain bonded to the UR1 and 16 months of orthodontic traction, the UR1 failed to erupt. A decision was therefore made for extraction and replacement. At the time of surgery, it was noted that the incisal edge of the crown was significantly resorbed. This report describes the presentation, investigation and management of the ectopic, impacted UR1 with a discussion of the possible aetiology of the resorption of the crown.
CPD/Clinical Relevance: This report describes the presentation, investigation and management of the ectopic, impacted UR1 with a discussion of the possible aetiology of the resorption of the crown.
Article
A healthy 8-year-old male presented to a new patient orthodontic clinic with an unerupted upper right central incisor (UR1). On clinical and radiographic examination, two supernumerary teeth were found. In keeping with Royal College of Surgeons Management of Unerupted Maxillary Incisors,1 the initial treatment plan included the surgical removal of the supernumeraries under general anaesthetic, with an exposure and bonding of the UR1. A sectional upper fixed appliance was used to create space for the UR1. Following 16 months of orthodontic treatment (including 12 months of orthodontic traction), the UR1 failed to erupt. The case was referred to the orthodontic–restorative dentistry multidisciplinary (MDT) clinic for further investigation and treatment planning where a decision was made to extract the UR1. At the time of surgery, it was noted that the incisal edge of the crown was significantly resorbed.
This report describes the presentation, investigation and management of the ectopic, impacted UR1 with a discussion of the possible aetiology of the resorption of the crown.
