Cranial Repair is a surgical procedure designed to help patients with traumatic brain injuries, debridement and decompression surgeries, or congenital cranial defects to return to their normal lives. A common problem with cranial repair surgery is the choice of material and price. Generally speaking, peek is the best choice of material for cranial repair. It is also the most recommended material for patients. The price of the material is linked to the area to be repaired. The specific cost can go to the hospital to consult. There is no standardized price. It depends on the size of the defect in different cases. As for cranial repair surgery, the material is the most important thing. A good material can not only improve the success rate of surgery. And it can reduce the chance of postoperative complications. There are titanium mesh and peek materials for skull repair, what is the difference between these two? As medicine advances, more and more cranial repair materials are becoming available for use. Plexiglass, light apatite and calcium phosphate bone cement materials, which were once used in clinical practice, have been gradually withdrawn from the medical arena due to their poor clinical results. Nowadays, the commonly used cranial bone repair material is titanium mesh, which is also a high-quality material that has been used for a long time with good results. However, the metal properties of titanium mesh often bring consequences such as sensitivity to hot and cold reactions and CT imaging errors to patients. Under the efforts of medical researchers, a new type of cranial bone repair material has been applied to clinical applications, that is, PEEK material. The scientific name of this material is polyether ether ketone, which is a kind of polymer biomaterials, in terms of elasticity, heat conduction, hardness, stability and other aspects of the human cranium is extremely close to the use of three-dimensional molding of the PEEK bone plate, can be a perfect fit with the skull structure, do not have to worry about the accuracy and aesthetics of the problem. Numerous clinical cases have shown that PEEK cranial bone repair materials have not been found to bring discomfort, so that PEEK is the current better choice for cranial bone repair.
