Selective laser melted titanium implants: a new technique for the reconstruction of extensive zygomatic complex defects

Abstract

The restoration of extensive zygomatic complex defects is a surgical challenge owing to the difficulty of accurately restoring the normal anatomy, symmetry, proper facial projection and facial width. In the present study, an extensive post-traumatic zygomatic bone defect was reconstructed using a custom-made implant that was made with a selective laser melting (SLM) technique. The computer-designed implant had the proper geometry and fit perfectly into the defect without requiring any intraoperative adjustments. A one-year follow-up revealed a stable outcome with no complications.

Bioactive treatment promotes osteoblast differentiation on titanium materials fabricated by selective laser melting technology

“…This technology enables us not only to fabricate simultaneously the porous structure and the main body of the implant but also to fabricate implants with complex structures and personalized implants fitted to the defect of each patient. The clinical applications of SLM technology for reconstructive surgery have been reported for patients with facial bone defects 6,7) . Although porous titanium and its alloys have a high biocompatibility and can achieve good mechanical stability when bone has grown into the pores, they do not bond directly to living bone 8) .…”
