Excellent Biocompatibility Non-cytotoxic, corrosion resistance non-carcinogenic, non-conductive and hydrolysis resistance Good biological characteristics and histocompatibility Capable to sustain repeated steam, ETO sterilization and Gamma irradiation Outstanding Bio-Mechnical Character Exceeding tensile strength to the native bone and provide better protection to the cerebrum Comparable mechanical strength to the artificial bone and capable to distract the stress effectively when deformity occurs Better Imaging Compatibility Non-magnetic and highly translucent to X-ray CT/MRI imaging without scattering or artifacts Better comfort after implanting Lighter weight and more comfort for bulky implant Good thermal insulation to eliminate malaise due to the different temperature Perfect Contour Reconstruction Precisely match the natural contour and convenient to implant Literature proves clinical complications rate of PEEK implant comparable to the Titanium implant High Performance Biomaterial World Leading Manufacturing Technology CAD/CAM technology allows to restore the defect models and reconstruct the natural contour of the brain Product Code Kontour innovative technology in designing and manufacturing Patient-Specific Implant was rewarded the Second Class of National Technology Award. Cert No. 2014-F-30801-2-04-R06 Block 12, No.6, Qinling Avenue, Caotang Technology Industry Base, Xi'an High-tech Zone, Xi'an, China, 710304 PEEK-OPTIMA polymer, provided by Invibio, is now recognized as a high performance biomaterial in worldwide. It is formulated to meet the most exacting in-vivo criteria and present excellent mechanical performance, plasticity, chemical resistance and biocompatibility. It is also capable to be repeatedly sterilized without impairing performance and behaves highly radiolucent CT/MRI imaging without scattering or artifacts. PEEK-OPTIMA polymer has been widely utilized in cardiovascular, dental, neurological and orthopaedic implants and globally accumulated more than 5 million implant cases 1. Resource data is quoted from FDA database In conjunction with the outstanding PEEK-OPTIMA polymer performance, Kontour Medical utilizes advanced CAD/CAM and 3D printing technologies to design and manufacture the world leading cranial implants 2.
