The new polyether ether ketone PEEK material, as a new type of medical implant material, stands out from the crowd of medical materials with its own excellent properties, 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 strong and does not risk denting under stress; it is well insulated, avoiding 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 material uses three-dimensional technology to reshape the bone plate, one-time technology molding, embedded in the skull can be and bone window tightly docked, the shape of the shape is more perfect.
