Multidisciplinary treatment approach for horizontal root fractures

The aim of this case report is to present a multidisciplinary treatment plan for horizontal root fracture of maxillary anterior teeth that resulted from trauma. A 16-year-old male presented a horizontal root fracture in the middle-third of teeth 11 and 21. Dislocated tooth fragments were repositioned using a composite splint technique. Follow-up examinations revealed the teeth lost vitality after trauma. Separated tooth fragments were removed by a surgical operation and then reattached using fiber post and resin cement. Teeth were replanted into the alveolar socket and splinted after root canal treatment. After 1 year of follow-up examinations, this comprehensive treatment was observed to be successful both clinically and radiographically. Horizontal root fractures can be treated successfully by extraoral reattaching of fractured segments and intentional replantation of teeth after root canal treatment.
