Peek material is slightly more expensive than titanium mesh, but its repair effect is really superior to any material currently available. At present, it is recommended to go to a large hospital in Beijing to find a more formal hospital and an experienced doctor to repair the skull with peek material. There are many patients who have had their skull repaired with this material and have had little or no discomfort after surgery. The titanium mesh, which is widely used nowadays, can cause complications in some patients after use in different cases, such as local pain, hot and cold sensitivity, interfering with medical examination, and poor cosmetic results. In contrast, peek materials have been used in surgical procedures for more than twenty years, and the good postoperative recovery of most patients has proven the excellence of peek materials. Indeed, peek material is excellent in all properties. In terms of its mechanical properties, it is extremely resistant to blows and can fully protect the brain tissue inside the skull; peek material can precisely replicate the defective part of the human skull and reconstruct the design through advanced 3D printing technology based on CT data to precisely match the defective area and meet the high requirements of patients for perfect recovery at the wound; its non-metallic material is more conducive to postoperative follow-up inspection and does not make the inspection Its non-metallic material is more conducive to post-operative follow-up examination, and will not cause artifacts in the examination results, and there is no headache and discomfort caused by thermal expansion and contraction; at the same time, the performance of peek material is stable, and there is basically no post-operative infection after repeated autoclaving. The skull repair with peek material is an embedded repair, unlike the titanium mesh which is an overlay repair that may bring cutting injury, and the skull appearance is very smooth after the repair with peek material. Therefore, peek material is the most ideal material for skull repair.
