The titanium net compares with the PEEK skull repair material.

The titanium net compares to PEEK cranium repair materials, and PEEK are two types of material that are of great interest in cranium repair. The titanium web is an early application for skull repair. Its advantages are, first and foremost, its robustness, which provides reliable protection for the fractured parts of the skull and effectively prevents external damage to the brain. In clinical applications, titanium webs are relatively easy to process and install and are technologically mature, and many hospitals are skilled in the relevant operations. Moreover, the price of titanium webs is lower than the PEEK material, which makes it more economically acceptable to more patients. However, the titanium web is also inadequate. Although its biocompatibility is still acceptable, there are still cases where some patients may become infected, extricated, etc. after the operation, which affects recovery. At the time of the video screening, the titanium web produced a pseudo-image, which was detrimental to patients who needed CT, MRI and could interfere with the diagnosis. In addition, the plasticization of the titanium web and the compatibility of the patient ‘ s skull are sometimes less than desirable and affect beauty. PEEK materials show unique advantages. Its biocompatibility is excellent and hardly causes an exclusivist reaction in the human body, significantly reducing the risk of complications such as post-operative infections. The elasticity of the PEEK material is very close to the human skull and reacts in a manner similar to the skull when exposed to external force, which better protects the brain. It has strong plastic powers, especially in combination with 3D printing techniques, which allow for a high degree of individualization, perfect alignment with the fractures of the patient ‘ s skull and good appearance recovery. At the same time, the pseudo-image produced by PEEK during the video-testing is minimal and does not interfere with subsequent diagnosis. However, the disadvantage of the PEK material is that it is expensive, which to some extent limits its wide application. In any case, the two materials are of good or bad quality, and the doctor selects the appropriate cranium repair material based on the patient ‘ s particular circumstances.
