Autogenous tooth fragment reattachment: a multidisciplinary management for complicated crown-root fracture with biologic width violation.

Fractures of multiple permanent anterior teeth can be a traumatic experience for children, with functional, esthetic and psychological aspects. The treatment of complicated crown-root fractures (CRFs) is more challenging when the biologic width is violated. This paper presents a case of 12-year boy with complicated CRF of teeth #12 and #21, and horizontal crown fracture of tooth #11. It was managed by endodontic treatment, mucoperiosteal surgery with osteotomy to visualize the fracture line for fragment reattachment, followed by fiber-post placement and restoration with polycarbonate crowns. Clinical and radiographic evaluation after 6 months was satisfactory with adequate functional and esthetic results.
