In recent years, cranial repair materials have undergone many improvements and innovations and are becoming more and more advanced. At present, the more commonly used cranial bone repair material is titanium mesh, which has made great progress compared with the traditional materials in the past, however, it is not particularly ideal and still has some problems. Many patients ask how much is titanium mesh for skull repair? Compared to traditional materials, titanium mesh has its advantages; however, when compared to the more advanced polyether ether ketone (PEEK) materials, the disadvantages of titanium mesh become apparent. Of course, one advantage of titanium mesh over PEEK is that it can be slightly less expensive. But its disadvantages are indeed many, such as titanium mesh is a metal material, higher thermal conductivity, insulation performance is not good, may cause sensitivity to hot and cold reactions; in addition may cause patients chronic pain, subcutaneous fluid, this metal material will also affect the future to do a variety of medical examinations, such as CT nuclear magnetic ah, will appear artifacts, causing diagnostic interference; in addition, titanium mesh tensile lightness, stability, elasticity, etc. also have a large Differences. If conditions allow, it is still recommended to do this polyetheretherketone repair. This PEEK material is bionic bone, can completely restore the anatomical structure of the skull, can be highly compatible with the autologous skull, and in terms of elasticity, heat transfer, hardness, stability, etc. are comparable to the performance of the autologous skull, especially for pediatric patients, can better adapt to the growth and development of the autologous skull.
