Cranial repair surgical materials are an important part of cranial repair surgery. A good material will not only increase the success rate of the surgery. It can also reduce the chances of postoperative discomfort. Thousands of years ago, doctors tried to use a variety of materials for cranial bone repair, limited to the medical knowledge and technological means backward, there is no suitable material for doctors to choose. With the advancement of medicine, more and more cranial repair materials have become 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apatite and calcium phosphate bone cement materials, which were once used in clinical practice, have been gradually withdrawn from the medical stage due to their poor clinical effects. 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. We use a new type of cranial bone repair material to do cranial bone repair surgery, the material is polyether ether ketone peek material, 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 human cranium, the use of three-dimensional molding after the PEEK bone plate, you can be completely with the cranial bone structure, do not have to worry about the accuracy and aesthetics of the problem. Numerous clinical cases show that the current has not been found PEEK skull repair materials brought discomfort, so that the PEEK material is a better material for repairing the skull.
