![]() ![]() SEM imaging revealed cells attaching to and bridging micro-topological features of the porous constructs, and cell activity was significantly greater for the porous PEEK compared to solid at multiple time points.ģD printing Bone ingrowth Fused filament fabrication PEEK Porosity Triply periodic minimal surface.Ĭopyright © 2020 Elsevier Ltd. zFuse TV supports ASS/SSA/SUP special effects subtitles, you can experience the complete special effects subtitle experience of the Mac/PC version. Average compressive properties ranged from 210 to 268 MPa for elastic modulus and 6.6-17.1 MPa for yield strength, with strength being greatest for TPMS constructs. HA is considered to be osteoconductive but not osteoinductive (Samavedi et al., 2013). zFuse TV can play all video formats and encodings, you dont need to convert the video file to MP4, you can play it on your mobile device, without file conversion. μCT imaging showed the porous networks to be open and interconnected, with porous sizes similar (p > 0.05) to the as-designed size of 600 μm. The samples were then imaged via scanning electron microscopy (SEM) to observe cell morphology. ZFUZE is a composite polymer derived from PEEK and negatively (-) charged ceramic aluminum silicate molecules. Multiple studies have shown the ZFUZE material elicits pro-reparative M2 macrophage response and significant. zfuse osteoconductive peek fda update marketplace. The porous PEEK, along with 3D printed solid PEEK, was then seeded with MC3T3-E1 preosteoblast cells for evaluation of cell proliferation and alkaline phosphatase (ALP) activity. Xiphos-ZF is the first spinal implant developed from a new biomaterial called ZFUZE. The material characteristics, including porosity, yield strength, and roughness, were evaluated using μCT, static compression testing, and optical profilometry. The designs of the porous structures were based on a simple rectilinear pattern as well as triply periodic minimal surfaces (TPMS), specifically gyroid and diamond types. Additional information for patients on reporting adverse events associated with stem cells, exosomes, or other products purporting to be regenerative medicine products can be found. In this study, we created porous PEEK via clinically-available fused filament fabrication (FFF, 3D printing) and assessed the pore structure morphology, mechanical properties, and biologic response. ZFUSE OSTEOCONDUCTIVE PEEK FDA UPDATE marketplace.Part B: Supplementary Information Sheet (SIS) The FDA monitors these reports and takes appropriate action to help ensure the safety of medical products in the U.S. Though concerns exist regarding PEEK for orthopaedic implants due to its bioinertness, the creation of porous networks has shown promising results for interaction with surrounding tissue. Due to its unique and advantageous material properties, polyetheretherketone (PEEK) is an attractive biomaterial for implantable devices. ![]()
