The Best Thing Next to Bone™ Introducing osseoincorporation to implant dentistry.

TRABECULAR METAL TECHNOLOGY Trabecular Metal Technology is an innovative material utilized by Zimmer for over 15 years in implantable orthopaedic devices. Uses of Trabecular Metal Material are varied and have included joint reconstruction, bone void filling and soft tissue repair.13 Zimmer Dental is currently working on multiple ways to integrate Trabecular Metal Technology into its oral rehabilitation portfolio. What is Trabecular Metal Technology? Trabecular Metal Technology is a three-dimensional material, not an implant surface or coating. Its structure is similar to cancellous bone.4 6 Figure...

How is Trabecular Metal Material Made? Trabecular Metal Material is fabricated in Zimmer’s TMT facility in Parsippany, New Jersey. The Trabecular Metal material process demands strict specifications for pore size, shape and interconnectivity to ensure a cancellous bone-like structure is obtained. Utilizing a thermal deposition process, elemental tantalum is deposited onto a substrate, creating a nanotextured surface topography to build Trabecular Metal Material, one atom at a time. This proprietary process utilizes the physical and biological properties of tantalum to create a unique material...

potential for bone ingrowth a Topography A glimpse inside Trabecular Metal Material reveals its uniform three-dimensional cellular architecture with up to 80% porosity.2-4,6,24,25 The entire surface area of Trabecular Metal Material exhibits a nanotextured topography.26,27 Figure 8 Nanotextured surface topography of Trabecular Metal struts Osseoincorporation Conventional textured or coated implant surfaces achieve bone-to-implant contact, or ongrowth.17 However, Trabecular Metal Material’s consistent, open and interconnected network of pores is designed for both ongrowth AND ingrowth, or osseoincorporation.2,4,24...

Bone Ingrowth in Canine Mandibular Models BONE TRABECULAR METAL In a study of Trabecular Metal Implants placed in canine mandibular models, evidence of ingrowth by maturing bone has been documented as early as two weeks after implantation.33,34 Further research is required to determine the rate of ingrowth and its effects on secondary stability in human dental applications. Figure 12 Documented ingrowth in canine mandible While other manufacturers have tried to mimic the attributes of Trabecular Metal Technology, sintered bead and other conventional porous coatings and materials differ significantly...
