The nanotexturing on PEEKplus interbody fusion devices is 4 million times smaller than the dimples on a golf ball.
Vallum’s Accelerated Neutral Atom Beam (ANAB) process superimposes 20-50 nanometer concavities directly into the surface of PEEK. Like the dimples on a golf ball – only 4 million times smaller.3
According to published papers, nanotextured surfaces less than 100 nanometers, like PEEKplus®, are known to improve osseointegration. 1,2,3,4
In addition, according to published papers, nanotexturing, like PEEKplus®, changes PEEK from its natural hydrophobic state to hydrophilic, which is also known to improve osseointegration. 3,4,5,6
A substantial investment in time and capital has gone into developing our Accelerated Neutral Atom Beam (ANAB) processing technology and our nano-processing techniques and protocols to create Vallum’s FDA cleared PEEKplus® nanotextured PEEK.
