The Arch Design . Camber ’ s Spira implants employ a series of arches which distribute loads and stresses throughout the implant itself — and , in the process , take advantage of Wollf ’ s Law to help improve osseointegration .
Macro , Micro and Nano Surface
Topography . Because of Camber ’ s additive manufacturing approach , the implant ’ s surface topography extends down three levels , macro , micro and nano , providing cells with multiple ways to attach and proliferate . The implant ’ s surface design is trabecular bone-like with an average pore diameter of just 500 µ m .
Subsidence Resistance . It ’ s called the “ snowshoe effect .” As you can see in the attached images , these designs distribute loads widely across the endplates . More surface area , decreases bone stress ( load / area ) and reduces subsidence risk .
More Bone Graft per Implant . Finally , because of the 3D printing process , Camber , like all companies using 3D printing , can create more space within each implant for bone graft .
