PEEK material, chemically named polyether ether ketone, is a special polymer material with high temperature resistance, chemical corrosion resistance and other physicochemical properties, in the aerospace field, the field of medical devices (as an artificial bone repair bone defects) and a large number of applications in the industrial field. Especially in recent years in the cranial bone repair, polyether ether ketone PEEK material with its excellent performance by the cranial bone defect patients and neurosurgeons favor, in the clinic to achieve outstanding repair results. Polyether ether ketone PEEK material performance: good mechanical properties: polyether ether ketone PEEK material has good hardness, strength, stiffness and good modulus of elasticity, can resist external impact, play a strong protective role. Tissue compatibility: polyether ether ketone PEEK material has good tissue compatibility and will not produce any rejection reaction. CT MRI compatibility: Polyetheretherketone PEEK material has no effect on radiation and magnetic fields, and will not affect the patient to receive CT MRI and other medical examinations. Three-dimensional shaping: Polyetheretherketone PEEK material can be three-dimensionally reconstructed and 3D printed according to the patient’s cranial CT data to produce a personalized material patch that highly restores the cranial structure, highly restores the cranial structure, tightly embedded in the bone window, smooth articulation, no abrasion of the scalp, and the shape of the head can be restored to the proportionality and aesthetics of the predeficiency period.
