The objective of this clinical report is to present decoronation of young permanent ankylosed incisors as an option to preserve the alveolar process in young people where implant rehabilitation is not yet indicated. A 13‐year‐old patient presented with intrusive luxation of the permanent maxillary lateral incisor and lateral luxation of both permanent maxillary central incisors. During 6 months, clinical and radiographic evaluation showed progressive root replacement resorption, and surgical decoronation was recommended for all three incisors and left for a period of 6 years until the implant and grafting procedures be performed. Decoronation in young teeth is a reliable technique in terms of preservation of the width and height of the alveolar process, and improves the aesthetic conditions after installation of the provisional prosthetics. Decoronation may be considered an alternative strategy for complex posttraumatic clinical scenarios, such as young ankylosed incisors.
