In life, a defect in the skull may occur due to some unavoidable factors, such as cranial trauma, such as surgery, and so on. This necessitates cranial repair. In fact, cranial bone repair surgery is already a relatively routine surgery in neurosurgery, and some local hospitals can also do it, but there are still many, many patients who are willing to go to Beijing to receive repair surgery, mainly because of the difference in the repair material. Which cranial repair is better? At present, the more widely used cranial bone repair material is titanium mesh, but this metal material is after all quite different from the autogenous bone, and there are also many problems, so it is not the ideal repair material. However, the clinical use of the latest cranial bone repair material – polyether ether ketone (PEEK) material is favored, can achieve the ideal repair effect. Polyether ether ketone PEEK this polymer material due to the material’s biocompatibility, can be complex molding, excellent mechanical properties, good protective properties, postoperative comfort, and gradually become the latest trend of cranial bone repair materials. At the same time, it is recommended that patients with cranial defects, cranial defects must go to the regular hospital for cranial bone repair, to avoid delaying the condition, triggering complications of other diseases.
