Abstract: A method for preparing bones of cerebral cranium, including: a) selecting polyetheretherketone (PEEK) as a raw material according to data obtained by computed tomography (CT) of a patient; b) heating the PEEK material in a heating device to reach a softening point of 260°±10°; c) hot pressing the heated PEEK material obtained in step b) in a forming die, cooling and shaping the PEEK material to yield a blank; d) curing the blank, and placing the blank in a thermostat for removal of internal stress and resilience; e) removing surface crystals and impurities of the blank resulting from the hot pressing; f) mechanically processing the blank according to the CT data of the patient to yield a product having desired size and shape; and g) washing, disinfecting, and packaging the product.
