Surgery, to the majority of patients with cranial damage to bring the gospel of recovery. With the development of science and technology, more and more new materials are used in cranial bone repair surgery, little by little replacing the traditional materials, favored by countless patients. The average patient with cranial bone damage has a heavy burden of thought. “If the bone window is missing, will it be infected to the brain tissue” “Is it that you can’t shake your head”. These concerns are normal, and if cranial repair is not performed in a timely manner or if the repair material chosen is not appropriate, it can cause the patient’s fears to become reality. In consideration of the safety and health of their own brain tissue, many patients choose the current advanced PEEK as the surgical material for cranial repair. Even though there are many successful cases, patients are still worried. Currently, there are tens of thousands of cranial bone repair surgeries in total, and every case can be said to be very successful. After the surgery, as long as the patient strictly follow the instructions of the doctor, recovery into a normal state is no problem at all. PEEK material can be three-dimensional customized, can completely restore the anatomical structure of the skull, in addition, this PEEK material is bionic bone, can be highly compatible with the autologous skull, and in the elasticity, heat conduction, hardness, stability and other aspects of the performance of the autologous skull and the autologous skull are comparable to the performance of the autologous skull, and can be better adapted to the autologous growth and development of the cranial bone.
