title: Intentional replantation with 180 degrees rotation of a crown-root fracture: a case report.
abstract: Crown root fractures are frequently difficult to treat and have a bad prognosis. To restore the biological space, intentional replantation can be chosen when osteotomy/osteoplasty and dental traction are not viable. Intentional replantation with tooth rotation consists of extraction, 180 degrees rotation and replantation, thus restoring the biological space. After treatment of inflammatory resorption with calcium hydroxide, endodontic treatment was completed. The patient was followed up with clinical examination (mobility test, gingival sulcus depth) and radiographic analysis (to analyze root resorption: inflammatory and/or substitution, and the integrity of the alveolar cortex and the periodontal space) for 3 years and there were no signs of resorption.
