Restoration of crown-root fractures with the involvement of supracrestal attached tissues represents difficulties for clinicians, as these types of fractures require a multidisciplinary approach for adequate treatment and successful prognosis. Depending on the location of the fracture, different treatment approaches, such as periodontal crown lengthening procedures, rapid orthodontic or surgical root extrusion or tooth extraction followed by fragment reattachment, direct composite restorations, veneers, and crown restorations, have been indicated.
This case report describes the management and long-term follow-up of the reattachment of a crown-root fracture using unidirectional fiber reinforcement after periodontal crown lengthening. Clinical and radiographic examinations of the reattached tooth after 7 years revealed favourable functional, physiological, and aesthetic outcomes and healthy surrounding periodontal structures, showing the success of the multidisciplinary treatment approach.
