Mandibular augmentation surgery, also known as mandibular augmentation surgery, is a very common plastic surgery. Many people don't know much about the plastic materials for chin augmentation. In fact, the material of chin augmentation prosthesis is basically similar to that of rhinoplasty. You can also use silicone like rhinoplasty, you can also use expansive materials, and you can also choose some new composite materials, but you should choose according to your own conditions, endurance and doctor's advice. Generally speaking, the materials of the chin are mainly solid silicone rubber, swelling material, autologous cartilage, injection filler and so on. Shijiazhuang Xingyuan plastic surgery experts pointed out that among the materials of chin implants, silica gel and expansion body are the most widely used at present, which have the following advantages: 1, easy to process sculptures, and can be molded at will to recreate a beautiful chin; 2. Mandibular augmentation with prosthesis is relatively simple, with slight pain and no need for hospitalization; 3. The prosthesis is safe, reliable, detachable and harmless to human body. Most chin augmentation operations are performed with solid silicone rubber. The operation process is mainly to make an incision in the oral cavity, then put solid silicone rubber in it, and then sew the incision, in this way to improve the defects of the chin. In fact, liquid silica gel is also one of the materials for chin augmentation, but this material has been eliminated because it is difficult to take it out in the chin.
