Which is the best material for cranial repair? Cranial repair is a common cranial defect surgery, in the cranial repair of the material used is very important, in the cranial repair of the time many people will ask to repair the material which is good this problem, then the following to understand in detail. At present, the first choice of cranial bone repair surgery material is polyether ether ketone (peek) material, the physical and chemical properties of this material and the human body’s own cranial bone properties are comparable to the organization of good compatibility, the modulus of elasticity and the autologous bone similar to the chemical properties of stability, resistance to high temperature and high pressure, resistance to the strike ability is strong, does not affect the postoperative radiological examination, and at the same time, good insulation, and will not be sensitive to heat and cold reaction. As early as thousands of years ago, human beings began the attempt of cranial bone repair. After thousands of years of development, the cranial bone repair material has gone through the development from animal bone, autologous bone to light apatite and calcium phosphate bone cement material, to metal material, titanium mesh, and finally to today’s most advanced polyether ether ketone material, it can be said that it has reached a considerable height. What is the best cranial bone repair material? Polyether ether ketone (PEEK) is the most advanced material used for cranial bone repair surgery, which can achieve relatively good results. This material is based on three-dimensional reconstruction of the patient’s cranial CT data, highly restored anatomical structure of the skull, precise anastomosis of the defective area, and this special material can be fused with the autologous skull, all in one, it is a very good cranial bone repair material.
