Machined Surface Technology
TiCro® machined surface technology is CTL Amedica's proprietary texture included on titanium and hybrid interbodies. This unique surface provides greater implant surface area when compared to predicates, enhances bone interlocking qualities, and helps to ensure cage placement.
Increased Surface Area
The unique pattern of TiCro®™ adds up to a 200% increase to the surface area of our implants, giving optimum space for bone purchase.
Enhanced Bone Interlocking
The dovetail pattern of the TiCro® surface texture not only gives enhanced purchase upon implantation, but upon fusion creates a dovetail joint...significantly increasing bone interlocking properties.
THE DOVETAIL JOINT
A dovetail is a joinery technique most commonly used in woodworking joinery (carpentry), including furniture, cabinets, log buildings, and traditional timber framing.
The dovetail joint is noted for its resistance to being pulled apart (tensile strength).
The dovetail joint technique probably pre-dates written history. Some of the earliest known examples of the dovetail joint are in ancient Egyptian furniture entombed with mummies dating from First Dynasty, the tombs of Chinese emperors, and a stone pillar at the Vazhappally Maha Siva Temple in India.
The dovetail joint is very strong because of the way the 'tails' and 'pins' are shaped. This makes it difficult to pull the joint apart and virtually impossible when glue is added.
This type of joint is used in box constructions such as drawers, jewelry boxes, cabinets and other pieces of furniture where strength is required. It is a difficult joint to make manually, requiring skilled workmanship.
What does this mean
At the point of fusion, CTL Amedica's TiCro® reverse dovetail surface texture increases bone interlocking strength by completing the dovetail joint as described above.
This design also provides up to a 200% increase in implant surface area over predicate devices.
The combination of increased surface area for bone growth, and the innate strength of a dovetail joint completed upon fusion, creates a surface texture that truly meets the needs of a spinal interbody.
