Abstract
The present study reports a case of coronoradicular fracture with the biological width invasion that was successfully managed by orthodontic root extrusion. Clinically, the patient presented with a subgingival fracture of the first maxillary premolar, with a tooth fragment 5.0 mm below the enamel-cementum junction. The initial examination suggested a poor prognosis for the clinical case; however, we decided to employ an orthodontic root extrusion over 5 months. After 1 year, a satisfactory prosthetic rehabilitation, associated with the periodontal health, could be observed and it can be concluded that orthodontic root extrusion is an essential tool for the management of extensive subgingival fractures.Clinical Relevance to Interdisciplinary DentistryExtrusion root is a conservative treatment.Root or coronal fractures can be treated with root extrusion.Prognosis of this type of treatment is extremely favorable.
