The cranium, also commonly known as the skull, plays a protective role for the human brain, and the human brain is the brain for the higher part of the nervous system, is the organ of thought, dominates all the activities in the organism and regulates the balance between the organism and the surrounding environment, so the cerebral cortex is the material basis of the higher neural activity. If a patient has a cranial defect, it is easy for the patient’s brain to be hurt by the outside world, and in serious cases, it will jeopardize the patient’s life. Therefore, when there is a defect in the cranial bone, the patient should have a cranial repair surgery as soon as possible when the physical condition permits. Cranial bone repair surgery is a conventional surgery, at present for patients to do cranial bone repair material or more, such as titanium mesh, titanium mesh is a traditional repair material, due to poor tissue compatibility, rejection and other reactions, so it is not recommended to take titanium mesh material to do cranial bone repair surgery. Currently a new polymer material PEEK material, PEEK material is good tissue compatibility, not easy to infection, PEEK material is based on the patient’s cranial CT data for three-dimensional shaping, the use of 3d printing, highly restore the physiological structure of the skull, the operation is mosaic surgery, no need for intraoperative molding, so that the safety of the operation and the effectiveness of the operation has been greatly enhanced. And through the recovery of the patient, and review found that the PEEK material can be repeated high temperature and high pressure sterilization, the effect is good. Warm tips: The above is a detailed introduction of what is 3D cranial bone repair, I hope it will help you. It is recommended that patients with cranial defects go to regular hospitals as soon as possible to choose the right material for repair and regain their health as soon as possible.
