Nowadays, medical science is more advanced, and although skull repair surgery is not a big operation, patients must choose a regular hospital and use safe and effective materials in order to ensure the safety and effect of the surgery. From before to now, there are still many materials that can be used for skull repair, such as bone cement and plexiglass in the early days, but these are no longer used due to various problems. And even the titanium mesh material, which is more widely used clinically at present, still has some problems, and the recovery effect after surgery is not ideal, and even needs to be repaired twice, which is very troublesome. Therefore, choosing a better material for repair is also a great help to the postoperative recovery. The stitches are usually removed within half a month after the skull repair, and the stitches can be removed in a shorter time for young people as the wound heals faster. Nowadays, with the improvement of technology and optimization of materials, the care and recovery time of cranial bone repair surgery is greatly shortened. More importantly, of course, is the choice of skull repair material. Many patients with no other medical conditions present after repair with PEEK material are generally free to move around three days after surgery. After a week of rehabilitation according to the doctor’s instructions, you can be discharged from the hospital to recuperate. Follow the doctor’s instructions for more rest and a light diet, and you can achieve full recovery in half a month to a month’s time. The polyether ether ketone peek is a material for repairing skull defects, on the one hand, to restore the integrity of the skull and improve the aesthetic appearance; on the other hand, to protect the brain tissue from damage, rebuild the complete closed cranial cavity, reshape the stable intracranial environment, to ensure normal intracranial activities and the normal operation of all brain and nerve functions. Polyetheretherketone peek is a new type of polymer material, through three-dimensional reconstruction, 3D printing, highly restored cranial structure, symmetrical on both sides after repair; polyetheretheretherketone peek has excellent performance, low rejection infection rate, does not affect CT MRI and other examinations, embedded repair, smooth articulation, high comfort, high mechanical strength of the material, strong impact resistance, good protection performance, polyetheretherketone peek has become the new trend of skull repair material.
