Gold Standard in Integrated Interbody™
Only Centinel Spine merges the established advantages of titanium with the subsidence resistance and
visualization benefits of PEEK and the proven clinical success of STALIF® technology to provide spine surgeons with titanium, endplate-facing,
Integrated Interbody™ systems.
Not All Titanium Surfaces are Created Equal.
Ti-ACTIVE™ is engineered with over 15 years of science and experience to produce an optimized surface topography enabling cellular proliferation.1, 2, 3, 4
Ti-ACTIVE™ is designed and manufactured with a highly refined process with rigorous inspection. In the manufacturing process, there are specific areas
of the implant that are masked in order to ensure that the surface maintains certain thickness and tensile strength characteristics.
The re-surfacing process is conducted by a robotic arm in a vacuum environment with controlled temperature and pressure for better control over
the quality and reproducibility of the surface.

Finally, the PEEK is heated to make it more receptive to the titanium resurfacing, and provide
the optimal environment for interdigitation of the titanium into the PEEK.
To ensure the final surface meets minimum required standards, 100% of all Ti-ACTIVE™ lots are inspected to verify surface thickness,
tensile strength, and porosity versus validation requirements.
When this surface was tested using the FDA ‘metal on metal’ testing protocols, it significantly exceeded FDA standards for shear and tensile bond strength.
All Centinel devices using Ti-ACTIVE™ are sterile-packed, avoiding the cyclic shrinking/stretching rates that may cause differing materials to separate
as they are heated and cooled during the sterilization processes.

One-and-Only STALIF® Combination.
Ti-ACTIVE is the only titanium surface to be combined with the STALIF No-Profile, Stand-Alone, Integrated Interbody technology.
Only STALIF devices with Ti-ACTIVE surface provide a three-point stability advantage with increased insertion friction,
increased surface contact area with bony endplates and compressive fixation at the graft site through a lag screw design.2, 7
The Lag Effect
Compressive lag fixation ensures biomechanical stability and provides secure graft-endplate contact. Lag screws reduce the
vertebral bodies onto the PEEK Cage creating graft / endplate surface compression to provide the best opportunity for fusion.
Ti-ACTIVE™ devices maintain the radiolucent advantage of PEEK, making it easier to assess post-operative development of
fusion mass during follow-up. Images show radiographs of STALIF C-Ti™ (left group) and STALIF M-Ti™ (right group) in
