Cranial Repair Surgery repair materials are very important. A good material will not only increase the success rate of the surgery. It can also reduce the chance of postoperative discomfort. Thousands of years ago, doctors tried to use a variety of materials for cranial bone repair, limited to the backwardness of medical knowledge and technical means, 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apatite and calcium phosphate bone cement materials, which were once used in clinical practice, have been gradually withdrawn from the medical stage due to their poor clinical effects.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 property of titanium mesh often brings consequences such as sensitive reaction to heat and cold and CT imaging errors to patients. At present, a new type of clinical cranial bone repair material, the material is polyether ether ketone peek material, which is a polymer biomaterial, 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 after the PEEK bone plate, you can and the cranial bone structure fits perfectly, do not have to worry about the accuracy and aesthetics of the problem. Numerous clinical cases have shown that there is no discomfort caused by PEEK cranial bone repair material, so PEEK material is a better material for cranial bone repair.
