From the present life, it seems that the cranial repair materials have undergone many improvements and innovations and become more and more advanced. The most common cranial repair material used in clinical practice is titanium mesh, which has made great progress compared to traditional materials in the past, but is not particularly 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 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 have used this advanced PEEK material to achieve excellent repair results and have received favorable comments from patients across the country. The repair material used in the skull repair is the very advanced peek material. In addition, this PEEK material is bionic bone, which can fully restore the anatomical structure of the skull and can be highly compatible with the autologous skull, and is comparable to the autologous skull in terms of elasticity, heat transfer, hardness, stability, etc., especially for pediatric patients, which can better adapt to the growth and development of the autologous skull.
