Currently, titanium mesh is the most commonly used material for skull repair surgery, and this material is not a very good choice, and has some problems and complications. However, with the advancement of medicine, a few hospitals have introduced a more advanced PEEK material to repair the skull to achieve better results. First, let’s understand the advantages of PEEK cranial bone: 1, the biggest benefit is that he is imitating the skull, in fact, in terms of mechanical properties alone, it is even more resistant than the skull to blows. 2, embedded in the repair, a tight fit. 3, will not be affected by sudden cold and heat 4, has a very strong inert, very little stimulation of the scalp. 4, PEEK skull and supporting cranial lock material in the design, will be reserved for the placement of connecting piece of the groove, the surgical operation is very convenient. 5, the rays are all permeable and do not produce metallic artifacts. PEEK is a new material that has emerged in recent years and is recognized by the international medical community for its clinical utility. Compared to traditional materials, the cost is definitely higher. However, from a medical standpoint, health is the most important thing. The key is that PEEK is clinically effective and no similar complications have been found in clinical practice. This is the greatest significance of PEEK as a cranial repair material, as it does not negatively impact the patient’s life.
