What is the material of cranial bone repair peek material? Cranial defect is one of the very common and diverse human congenital anomalies, which seriously affects the physical and mental health and quality of life of patients, especially large cranial defects caused by trauma, tumor resection and vascular injury. Currently, the most common treatments used for cranial injuries are autologous bone and allogeneic bone grafts. However, autologous bone grafts often face the challenges of shape matching and limited sources, and allogeneic bone grafts are prone to immune rejection. Because of skull repair, many skull repair materials have “emerged,” with titanium mesh and PEEK being widely used. Although titanium mesh has its advantages, there are still many disadvantages. Titanium mesh manufacturers are disorganized, and because of the high technical requirements of titanium processing, the quality of shaping varies, especially for patients with osteoporosis, and poor fitting problems often occur. Second, titanium mesh is affected by temperature. Moreover, due to the inherent deficiencies of titanium mesh, it is difficult to perfectly shape the curved parts of the head, such as the forehead and the arch of the eyebrows, and there may be traces of mesh after implantation, making the visual effect less favorable. PEEK (polyetheretherketone) is a special engineering plastic that looks similar to ordinary plastic, but has many advantages such as high temperature resistance, corrosion resistance, robustness, and good toughness and fatigue resistance. It is strong but flexible, with a weight and texture very close to human bone, even if subjected to collisions without denting or deformation, PEEK cranial repair perfectly makes up for the shortcomings of titanium mesh.
