Many people have to undergo cranial bone repair surgery because of one reason or another in their lives. The key to skull repair surgery is the need to choose a better skull repair material. At present, the more widely used material in the clinic is titanium mesh, this material still has some less than ideal situation, can not be complex shaping; cause painful metal cutting; titanium alloy’s heat insulation performance is not very good, easy to cause patients sensitive to hot and cold reaction after surgery; titanium alloy’s tissue compatibility is also not too perfect, some patients may appear rejection reaction; titanium alloy this metal material, may affect, patients receive post-operative CT, MRI and other medical examinations and other problems, which seriously restrict the quality of life of patients in the future. What is the cost of skull repair? Currently, the clinical use of new PEEK material, is the current medical field of emerging polymer materials, has good mechanical properties, plasticity, chemical stability and biocompatibility, can withstand high temperature steam and irradiation sterilization, and radioactive permeability and magnetic resonance scanning will not produce artifacts, smaller density, lighter weight implants more comfortable, will not conduct heat. Little to no postoperative vital rejection or adverse symptoms have been observed.
