EIT Cellular Titanium®

EIT Cellular Titanium® structures are produced with SLM technology and allow the creation of highly porous macro-, micro- and nano-structures that are close to cortical and cancellous bone, leading to a fast and extensive bone incorporation.

EIT Cellular Titanium®

  • EIT Cellular Titanium® implants are produced with Selective Laser Melting (SLM) technique

  • EIT Cellular Titanium® consists of  ~ 80% porosity and a diamond pore size of ~ 650 μm, mimicking trabecular bone structure
    » Bone grafting is not necessary

  • Combination of solid and cellular implant architecture facilitates the rebuilding of natural cortical and cancellous bone structure
    » Provides optimal biomechanical and biological environment for natural bone ingrowth
  • Hydrophilic EIT Cellular Titanium®
    » Maximized blood contact leads to accelerated protein and mesenchymal cell attachment and bone cell differentiation
    » Proven biocompatibility of titanium alloy TiAl6V4

  • Excellent imaging characteristics
    » Implant contours visible under x-ray. Fusion area clearly visible due to high implant porosity
    » MRI and CT compatible

Macro-, Micro-, Nanostructural features

Macro-structure

  • Rough EIT Cellular Titanium® surface provides high primary implant stability
  • Modulus of elasticity close to cancellous bone avoids stress shielding and implant subsidence 

Micro-structure

  • Scaffold surface roughness and ~ 80% porosity provides maximized contact area and mechanical support of bone cells and vascular structures from one endplate to another
  • Ideal pore size of ~ 650 μm facilitates a fast natural cellular influx, leading to a solid bony fusion and subsequent secondary stability

Nano-structure

  • Chemical surface treatments create an optimal environment for bone cell formation and bone apposition over the entire EIT Cellular Titanium® lattice
  • Rough titanium alloy increases osteoblast proliferation, BMP response and stimulates an angiogenicosteogenic environment
