Recurrence of a Diastema Following Orthodontic Treatment Associated with the Persistence of the Upper Labial Frenum: Indication for Frenectomy in a Pediatric Patient Using an Electric Scalpel

The presence of a low-insertion upper labial frenum is frequently associated with the persistence or recurrence of a maxillary mid-incisal diastema, even following successful prior orthodontic treatment. In paediatric patients, particularly during the mixed dentition phase, the choice of surgical technique for frenectomy requires careful consideration of haemostasis, post-operative comfort, behavioural management and cost-effectiveness. The purpose of this article is to present a case of frenectomy performed using the electrosurgery technique (electric scalpel) for recurrence of a diastema caused by the upper labial frenum, even after orthodontic treatment, in a 9-years-old child. The indications, contraindications, techniques, advantages and disadvantages for rational application in paediatric dentistry were discussed, as well as highlighting best practices for paediatric dental management.
