The skull is not only the protective layer of soft tissue in the brain, but it is also important for maintaining the aesthetics of the head. And life is often full of accidents, perhaps an inadvertent collision will make our skull lose a piece. If not repaired in time, not only the normal functional environment of the brain can not be guaranteed, but also will cause a great burden on the patient’s psychology. What are the best materials for cranial bone repair? The choice of material for cranial repair is very critical, and now there are many materials for cranial repair, which makes it difficult for patients to choose cranial repair materials, and they don’t know which material is better for cranial repair. Nowadays, most hospitals generally use titanium mesh material for cranial bone repair surgery. However, there are still some problems with titanium mesh material. For example, patients are sensitive to hot and cold reaction after the operation, there is chronic pain in the local area, and there is more subcutaneous fluid; after the repair operation, it affects the patients to receive CT, MRI and other medical examinations. At present, the repair material used in our cranial bone repair surgery is the very advanced PEEK material. It can completely restore the anatomical structure of the skull, in addition, this PEEK material is bionic bone, which can be highly compatible with the autologous skull, and in terms of elasticity, heat conduction, hardness, stability, etc., are comparable to the performance of the autologous skull, especially for children patients, and can be better adapted to the autologous cranium’s growth and development. the main advantages of the PEEK are that it does not produce CT or MRI artifacts, and the implant is more comfortable, because the material is less dense and weighs less. The material is less dense and lighter; unlike metal implants that transmit heat.
