About NEST
NEST Interbody System is a hollow, rectangular implant that consists of a unique configuration of both solid and porous structures, which are built using Paonan's 3D printing Titanium technology.
The system was designed for bone in‑growth and biological fixation. Inspired by the microstructure of cancellous bone, and enabled by Paonan's 3D printing manufacturing process, this technology is deliberately designed for fusion.
Why Titanium?
To seek a new material for next generation spine surgery, Paonan Biotech started from scratch to create an osteo influential and effective implant designs. Our own Titanium material allows us to produce porous titanium cages that combine the biocompatibility of titanium material with improved bone incorporative and biomechanical qualities. The porous titanium cage combines specific macro structural, micro structural and nano structural characteristics, which synergistically influence the bony fusion process.
