In the current life there are all kinds of accidents, a falling object, a traffic accident will bring different degrees of damage to our body, such as a missing piece of skull. We all know very well that the skull is the protective layer of the brain tissue, the missing skull not only affects the appearance of the aesthetic, but also will bring irreversible damage to our health. In children, it is possible to grow back a small area of missing skull bone, but if the missing area is too large, it is unlikely to grow back on its own, and in adults, the possibility of self-healing is unlikely to be high if there is a missing skull bone. So don’t take any chances and go to the hospital to have a skull repair surgery in time. Regarding the skull repair surgery, the choice of material is very critical, many hospitals commonly use titanium mesh material for skull repair surgery, although there is a certain effect, but this material also has many shortcomings. For example, postoperative rejection reaction, affecting the future of the CT nuclear magnetic examination, the material is exposed to the need for secondary repair, etc., the patient is doubly painful and helpless. It is in the case that patients feel discouraged and desperate, a new type of polyether ether ketone material came into being, also known as PEEK material, PEEK material has a certain uniqueness and advanced, its performance is comparable to the autologous skull, but also according to the patient’s skull structure for personalized three-dimensional design and customization, highly restored to the patient’s skull shape, the effect of the postoperative effect is very beautiful. PEEK material has become a better material for cranial bone repair surgery.
