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 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. What are the advantages and disadvantages of 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 more; 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 permit, it is still recommended to do this polyetheretherketone repair. We use this advanced PEEK material to achieve very good repair results and get good reviews from patients all over the country. PEEK is recommended for skull repair and has been recognized and praised by patients as the preferred material for skull repair.
