Following the vest line, A4 waist, the Internet has emerged a new wave of fashion indicators – high cranial top. You can see Liu Tianxian’s superior high cranial top, so how many female celebrities are overshadowed. So there are a lot of bottom cranial top people thinking how to have the same cranial top. There are also many strategies on the Internet, the most common is the wig piece. We do not judge this surgery this surgery, single out this material. Bone cement bone cement is actually an adhesive, which is a medical material commonly used in orthopedic surgery. Its physical properties and appearance after solidification are especially like white cement used in construction and decoration, so it has this common name, which is more graphic and easy for patients to understand. The main component of bone cement is polymethylmethacrylate, which has been used clinically since about the early 1960s. In order to facilitate transportation and storage, the bone cement is designed to be a white powder and a liquid with a colorless and irritating odor, and when used, the two are simply mixed and it begins to polymerize at room temperature. It starts in a sandy form, gradually transitions to a thin porridge and finally to a dough-like form. During the dough period, the bone cement can be kneaded and squeezed at will to form any shape, and the process of polymerization to completion of hardening takes about ten minutes. Bone cement can be used to fill and repair partial bone defects and to fill the bone defect areas. This is also commonly referred to as cranial repair surgery. Bone cement is used as a medical cranial repair material. It has the following advantages: 1. It has strong plasticity, which can precisely restore the missing part of the skull of the patient and improve the safety factor of the repaired part after the operation. 2.Patients feel comfortable after implantation, no heat and cold sensation. 3.The strength and hardness are similar to bone tissue. 4.The quality is light, so that the patient does not feel foreign body. 5.Can be sterilized by high temperature and pressure. 6.Applicable to postoperative radiation transmission. However, this material is rarely used clinically as a repair material. Replaced by a more superior performance of polyetheretherketone material. It is also commonly known as peek cranial repair material. It has better performance than bone cement and is more compatible with human tissue, making it the best choice for cranial repair. Cranial repair surgery is a kind of surgery that does not enter the brain tissue, and the surgery is done outside the cerebral cortex, especially outside the dura, or outside the scar after the first surgery, or outside the fascia. Therefore, skull repair surgery is generally safe, and the technology of surgery has been relatively mature, and the success rate of surgery is very high if you choose an experienced physician, so patients do not need to worry too much.
