In recent years, cranial repair materials have undergone many improvements and innovations and are becoming more and more advanced. Titanium mesh is the most commonly used cranial repair material in clinical practice, but it is not ideal and still has some problems. Compared with traditional materials, titanium mesh has its advantages; however, when compared with the more advanced polyether ether ketone (PEEK) materials, the disadvantages of titanium mesh become apparent. Of course, one of the advantages 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, resulting in 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. We have used this advanced PEEK material to achieve very good repair results, which have been well received by many patients. PEEK is recommended for cranial repair, which has been recognized and praised by patients as the preferred material for cranial repair.
