A Novel Use of Biomaterial Implants for Reconstruction of Orbital Floor Fracture

Abstract

Introduction: The progress in the field of biotechnology offers new materials for the reconstruction of orbital fractures. However, the choice of the best material for orbital floor repairs is still a controversial issue. In this paper the authors introduce the use of zirconium oxide implants for the first time in the reconstruction of orbital floor defects. Aim: Evaluate the clinical outcome of zirconium oxide implant material used for orbital floor repairs. Materials and Methods: From January 2008 to January 2015, six patients with orbital floor fractures referred to the Oral and Maxillofacial Surgery Department in Ramadi Teaching Hospital were surgically treated using zirconium oxide ceramic implants. The patients were examined after 7 days, 3 months and 2 years. Results: All cases achieved significant improvements in terms of diplopia and enophthalmos. No material related complications were reported in all treated cases. Post-operative radiograph and Computed Tomography Scans (CT) demonstrated that anatomical reduction of the orbital floor had been achieved.Conclusion: The study suggests that a zirconium oxide ceramic implant is a suitable implant biomaterial for the reconstruction of orbital floor fractures.
