The history of cranial repair is also very long, and after a long time of development, the technology of cranial repair has been progressing and improving, and under modern medical conditions, cranial repair has become very mature. The factors that have a great influence on the effect of cranial repair are the selection of cranial repair materials. The most common cranial repair material used in clinical practice is titanium mesh material. The performance of this technical material is somewhat advanced compared to the more traditional materials of the past, but there are also certain problems. In the process of clinical use, there may be some defects and shortcomings, such as postoperative infection rejection, wear and tear of the scalp resulting in scalp damage, material exposure; material is not insulated, the patient may be sensitive to the external hot and cold environment after surgery, resulting in discomfort; material hardness is not enough, it is easy to deformation by external force, resulting in scalp collapse; in addition, this titanium mesh metal material will also affect the patient to receive ct nuclear magnetic and other medical The examination, and so on. Therefore, although titanium mesh is more commonly used, it is not the ideal material for skull repair. At present, there is a more advanced new cranial repair material – polyether ether ketone peek material, which is a new type of special polymer material, its performance is almost equivalent to the human cranial bone, in terms of hardness, elasticity, thermal insulation, histocompatibility, etc. are very good, can achieve more ideal results, very good It overcomes the above-mentioned problems that may arise from titanium mesh. What’s more, this peek material can be shaped by personalized 3D reconstruction according to the patient’s skull shape, which can highly restore the skull structure of the patient’s head and achieve a well-proportioned and beautiful appearance.
