In recent years, cranial repair materials have undergone many improvements and innovations and are becoming more and more advanced. The titanium mesh is the most commonly used cranial repair material in clinical practice, but it is not ideal and still has some problems compared to traditional materials. 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 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, 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 polyether ether ketone repair, we use this advanced PEEK material, to achieve very good repair results, to obtain the praise of patients from all over the country. In addition, this PEEK material is bionic bone, can fully 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.
