Biolign™ Ti TLIF
> Enables optimum in-growth
> Serves as osteoconductive scaffold for bone growth into the material of the implant and vascularization
> Anatomically shaped to form part of natural end-late curvature
> 2 lateral lengths ensures large bearing surface, minimizing risk of subsidence
> Tantalum markers ensure higher flouroscopic imaging visibility than titanium
> Variety of heights 6mm - 12mm

POROUS STRUCTURE PROPERTIES
With Additive Manufacturing 3D metal networks can be CAD designed and built up together with devices’ solid parts.
Porous surface friction against bone can be adjusted according to specific needs. Example of friction coefficients obtained (Symbols identify four different porous structures tested).
Additive Manufactured metal porous structures can achieve high adhesion and cohesion strengths, in full agreement with standards.
Net to bulk adhesion strength is 3D metal network design dependent. Values showed are relative to a couple of porous structures designed and manufactured for exemplification purposes.
BIOLOGICAL POROUS STRUCTURE CHARACTERIZATION
In vitro tests have assessed cell viability and proliferation in Additive Manufactured titanium networks.
FOR PROPERLY DESIGNED AND MANUFACTURED POROUS STRUCTURES IN VIVO TESTS HAVE SHOWN:
bone ingrowth into AM lattice structures
healthy bone near the implants
improved implant fixation strength
