After millennia of development, current repair techniques have been perfected with low surgical risk and high efficiency. Patients also do not have to worry about not getting a good repair of the skull, resulting in potential threats to the brain tissue in the skull from the environment. Patients often ask what the price cost of cranial repair surgery is when they are repairing their skull, and this is undoubtedly a concern. The cost of skull repair depends more on the cost of the surgical material chosen for the skull repair material used PEEK, an emerging polymer material in the current medical field, so choose the regular material to be assured of the surgery. The current clinical application of a new polyetheretherketone peek material for skull repair. The PEEK material used for cranial repair is an emerging polymer material in the current medical field, with good mechanical properties, easy plasticity, chemical stability and biocompatibility, can withstand high temperature steam and irradiation sterilization, and radioactive permeability and magnetic resonance scanning will not produce artifacts, smaller density, lighter weight implants are more comfortable and do not conduct heat. Few vital rejection reactions and adverse symptoms have been observed after surgery. From the clinical cases, the patients are in good health without any complications to date. PEEK is the emerging material for cranial bone repair, allowing cranial bone repair to move into a new area of development and application. Therefore, patients are assured of treatment.
