“Trabecular MetalTM implants are fabricated of elemental tantalum metal using a vapor deposition technique to create a metallic strut configuration that is similar to trabecular bone. The resulting crystalline nano-texture permits direct bone apposition” – Zimmer Dental.
That’s a mouthful, and in essence means Zimmer’s new implant looks and acts like bone. The new design presumably results in quicker and stronger integration. The designed voids are much larger than natural bone, allowing more, and faster, ‘ingrowth’ (natural bone growing into the implant). This design provides more flexibility, and exhibits mechanical properties closer to cancellous bone than any other material.
