Aim: Crown fractures of maxillary incisors due to trauma are among the most common dental injuries in children and young adults. Treatment becomes advantageous when reattachment of the broken piece is possible. The purpose of this case report is; Rehabilitation and follow-up of traumatized maxillary central incisor with complicated crown fracture with reattachment technique. Case Report: In the intraoral examination of a 10-year-old girl who applied to our clinic due to a traumatic dental injury, a complicated crown fracture involving the pulp was detected in the middle third of tooth number 21. Detailed intraoral and radiological examination did not reveal any changes in mobility and periodontal tissues. Since the broken piece was kept in water and brought back, it was decided to stick it in place with a reattachment. Previously, root canal treatment was applied to the involved tooth in a single session. He enamel surfaces of the teeth were roughened with 37% phosphoric acid, then washed and air dried. In the same way, the broken part was cleaned and the connection surfaces were roughened with 37% phosphoric acid for 30 seconds, washed and air-dried. A universal adhesive system (3M Scotchbond Universal Adhesive) was applied to all surfaces of both the tooth in the mouth and the broken part to be bonded, and it was light-cured for 10 seconds. A thin layer of composite (Charisma Smart Kulzer A-2) was placed between the broken piece and the tooth, adapted to the tooth with finger pressure and polymerized with a light device for 20 seconds. After finishing and polishing, the case was completed and the patient was called for controls. Clinical Considerations: The ‘reattachment’ technique gives successful results in the restoration of complicated crown fractures caused by trauma. The restoration made with the patient’s own teeth creates an aesthetic appearance that is compatible with his natural teeth.
