title: Surgical extrusion of multiple teeth with crown-root fractures: a case report with 18-months follow up.
abstract: The objective of this case report is to describe the treatment procedure involved in surgical extrusion of multiple crown-root fractures and review the critical factors to be considered for successful and predictable outcome. The treatment of complicated crown-root fracture in anterior teeth is likely to compromise function and aesthetics when approached with conventional surgical crown lengthening. Orthodontic extrusion has also been suggested; however, it is time-consuming, aesthetically compromising and hardly applicable on multiple anterior crown-root fractures due to the limited source of anchorage. To overcome the shortcomings of suggested treatment modalities, we performed atraumatic surgical extrusion of four anterior fractured teeth along with their rotation within the sockets. The teeth were gently luxated and extruded to the desired position, minimizing damage to the marginal alveolar bone and root surfaces without rigid splint. The treated teeth were functioning normally 18 months after the procedure, and the mobility and probing depths were within normal limits. Radiographs revealed functional periodontal ligament space along with lamina dura formation around the extruded roots. There was neither root resorption nor significant marginal bone loss. This technique might be a promising alternative to conventional crown lengthening, especially in the anterior zone to avoid functional or aesthetic complications.
