About Tesera Trabecular Technology (T3)…

Tesera implants feature porous titanium surfaces which create the optimal environment for bone on-growth and in-growth. (Figure 1) Independent study of the Tesera structure proves rapid and complete bone ingrowth at 12 weeks, without press-fit or biologics. (Figure 2)

Tesera implants combine revolutionary manufacturing technology, advanced material science and bio-analogous design into cutting-edge implants that push the expectations of how spinal implants interact with the body.
