| Summary: | This case report aims to document the decoronation treatment of a patient with a history of dental trauma and replacement resorption. The objective of this procedure is to preserve the volume of the alveolar bone by promoting the displacement of the resorbed root with bone tissue.
A 12-year-old girl presented to our clinic due to discoloration and infraposition of tooth #21, which was avulsed and reimplanted three years ago. Clinical and radiographic examination revealed that teeth were ankylosed and replacement resorption was noticed in the apical region. As part of the planned decoronation, the gutta-percha was removed. Following local anesthesia, the full-thickness buccal mucoperiosteal flap was raised. The Crown of the central incisor was sectioned at the enamel-cementum junction. After irrigation with saline solution, the root canal was filled with a blood clot, the wound edges were approximated without tension, and the flap was sutured. A modified Nance appliance was fabricated for the patient to prevent space loss and achieve functional and aesthetic rehabilitationxz.
Decoronation may be advisable for patients in the growth stage to avoid negative consequences due to ankylosis. Decoronation is a more reliable and conservative procedure compared to the traumatic extraction of an ankylosed tooth. Maintaining the existing space after decoronation is necessary for future implant and prosthetic treatments.
In cases where infraposition occurs as a result of ankylosis, decoronation is required to maintain alveolar growth and integrity. Decoronation treatment can offer a predictable rehabilitation option for future implant planning. |
