With the development of medical technology and the progress of material science, many polymer bionic materials have been applied to medical clinics. The application of a large number of polymer materials has solved the material problems of many important surgeries for doctors, and also brought the gospel to the majority of patients. As a new type of medical implant material, PEEK material stands out among many medical materials by virtue of its own excellent characteristics, and has become a popular material for cranial bone repair. PEEK is an excellent material with properties closest to those of human bones. Traditional titanium mesh materials have a modulus of elasticity that greatly exceeds that of bone. When used as a cranial bone repair material, it leads to slower bone healing and even bone degradation. PEEK, on the other hand, has a modulus of elasticity that is very close to that of bone, and the stresses on the bone are not entirely borne by the implant, resulting in healthier bones. PEEK is also strong and does not have the risk of sinking under stress; it is well insulated and avoids expansion and contraction from heat and cold. Titanium mesh material has good heat transfer, but this is a major disadvantage for patients. When the patient is subjected to external hot and cold temperature differences, there is a change in the environment of the cranial cavity, which can affect the sense of comfort. This is also the main reason for many complications in cranial repair surgery.PEEK materials use three-dimensional technology to reshape the bone plate, one-time technology molding, embedded in the skull can be and bone window tight docking, the shape of the shape is more perfect. Although PEEK material has not been used in cranial bone repair for a long time, it has not been used as a medical implant material in the clinic for a short time. Meanwhile, countless patients have undergone PEEK material repair surgeries in the past ten years, and so far, there has not been a single case of complications caused by the longevity of the cranial material. A large amount of data and facts have proved that PEEK is the best cranial bone repair material at present, and patients can be completely relieved.
