کاربرد پلیمر پیک یا پلی اتراترکتون در ایمپلنت های ارتوپدی

The polyetheretherketone (PEEK) polymer has been identified as a promising material to be utilized in orthopedic implants. The main reason for interest in using PEEK in orthopedic implants is its mechanical properties, which could provide effective biomechanical advantages while preserving the mechanobiological benefits of implant. In other words, the mechanical and biological side effects of current metallic orthopedic implants on the bone tissue could be reduced by PEEK for better treatment of the bone injuries. a

The principle advantage of the PEEK is the close resemblance of the mechanical properties of this material with cortical human bone, which makes it a good substitutive material for metal orthopedic implants. In addition, the lack of electrochemical activity of PEEK in vivo with active ions of the body fluid should give this material excellent corrosion resistance and biocompatibility. Furthermore, the strong
intermolecular bonds have made PEEK material with considerable fatigue strength, wear resistance, tensile strength, compressive strength, and ductility. All these superior characteristics have motivated biomechanical and biomaterial researchers and orthopedic manufacturers to develop PEEK polymer in combination with other fillers such as carbon fiber, hydroxyapatite, etc. to promote the mechanical and
biological benefits of the PEEK polymer for use in orthopedic implants. a
