PEEK is a very mature material that has been widely used in many countries, not only as a cranial repair material but also for spinal surgery, including the arch nail, lateral block nail have peek material. Although its mechanical properties are good, and very suitable for human implants, but not many domestic do, the main reason or medical costs in the constraints of peek’s widespread use. The biggest advantage of PEEK is that it mimics cranial bone. In fact, in terms of mechanical properties alone, it is even more resistant than cranial bone, which is incomparable to titanium mesh or craniomaxillary superiority. And because it is an embedded repair, the review film is beautiful and tight after it is done. Titanium mesh can not, different manufacturers are too different, some manufacturers are really good shaping, absolutely fit; some manufacturers warp here and there, in the case of osteoporotic patients will be very troublesome. PEEK is a material that does not have this problem, and it is not a problem at all, and it is not affected by heat or cold. The skull repair surgery is a Class II procedure with very low technical difficulty, just like putting the bone flap back in place, as long as it does not press on the softened brain below, the problem is minor. In addition, PEEK material is permeable to radiation and does not produce metallic artifacts, and another great advantage is that it is inherently inert and has very little scalp irritation, which is a very prominent advantage compared to titanium mesh. PEEK is a little better in this regard, as it is designed with a groove for the connecting piece, which is a very thoughtful design so that the nail and plate do not buckle up and cause less skin irritation. Through the above introduction, I believe that you have a certain understanding of polyetheretherketone PEEK material. Therefore, doctors recommend that we all, develop good habits and pay attention to their own safety, so as not to be wrong on health hazards.
