Reattachment of a Complicated Crown-Root Fracture: 14 Year Follow-up
Objectives: Complicated crown-root fractures with the involvement of the biological width require immediate attention with a multidisciplinary approach for adequate treatment and successful prognosis.
This case report describes the 14-year-follow-up of the reattachment of a complicated crown-root fracture with the involvement of supracrestal attached tissues.
Methods: A 30-year-old female was referred to the Faculty of Dentistry Department of Restorative Dentistry after a traumatic dental injury caused by a car accident. Clinical and radiographical examination revealed a complicated crown-root fracture of the right endodontically treated maxillary central incisor. Upon agreeing on the reattachment of the crown-root fragment to the remnant tooth, informed consent was obtained from the patient. As the fracture was subgingivally located and extended apically to the bone crest, reattachment of the crown-root fragment was performed during an open flap surgery with osseous resection. After isolation and hemorrhage control, a two-step self-etch adhesive (Clearfil SE Bond; Kuraray) was applied on the crown-root fragment and remnant tooth and polymerized. Along with a thin layer of a flowable composite (Clearfil Majesty Flow; Kuraray) a unidirectional pre-impregnated fiber (EverStick C&B; GC) was pressed into the root canal of the remnant tooth and polymerized. Following checking the fit of the fragment, a micro-hybrid composite (G-aenial; GC) was applied to the crown-root fragment, the fragment was placed on the fracture site and the composite was polymerized through the attached tooth. The clinical situation of the reattached tooth was confirmed by clinical assessments at 1 2, 5, 7, and 14 years.
Results: Clinical and radiographical examinations of the reattached tooth after 14 years revealed favorable functional and esthetic outcomes and biomimetic characteristics of the anterior teeth and surrounding periodontal structures.
Conclusions: Reattachment of complicated crown-root fractures with the involvement of supracrestal attached tissues presents a reliable and long-term successful treatment option with the multidisciplinary treatment approach.
