& ltp> A: Under normal circumstances, this kind of operation will not be performed, because bone tissue is not as convenient as filling materials. In addition, bone tissue implantation has been tried as a filling material before, but the effect is not ideal, because there are smiling blood vessels and nerves in the bone, there will be a high probability of bone absorption within 2-3 years after implantation in the chin, and the bone absorption will be embarrassing, and the originally good chin line will become distorted. It will be even worse to take it out then. So this idea has been ruled out in medicine. At present, there are three kinds of chin fillings: hyaluronic acid, fat and prosthesis. I think you can consider silicone prosthesis for chin augmentation, or a material called 3D printing for chin filling. This technology is only available in South Korea at present, and it is still quite powerful, but it is a bit expensive. Many people will use this material to repair the failed contour, so it is much wrong to fill the chin. You can click on the picture below to see the details! That's my answer. I hope I can help you. & lt/p & gt； & ltp style = \ " text-align:center； \ " & gt& lta href = \ "/yiyuan/38/GL _ 10448 . html \ " target = \ " _ self \ " & gt； & ltimg src = \ "/uploadfile/image/20200317/158441625 2855497.png \" title = \ "Can mandibular angle osteotomy do chin filling \" alt=\" mandibular angle osteotomy?
