Having a perfect chin can highlight the contour of the face and make people look more beautiful, so everyone wants to make their chin more perfect and beautiful through chin plastic. So what kind of chin is perfect? According to the golden ratio of human aesthetics, after the lips are closed, the length of the chin is 0.6 times of 65438+ the thickness of the lips, or the length of the chin should account for one sixth of the length of the whole face, and the position of the lowest edge of the chin should be on the same vertical line with the eyebrows when viewed from the side. It is generally believed that the ideal chin length position is about the vertical line of the lower lip, while the chin is too short on the vertical line and too long outside the line. The aesthetic standard of chin The chin and mandible are a whole and inseparable in anatomical structure. They are isomorphic to the lower third of our faces. There are also certain standards in visual aesthetics: the interconnected lines should be smooth and conform to a certain curvature, the length of the lower third of the face should be less than the length of Yumei to the target, and the distance from the nose to the lower lip is about half the distance from the lower lip to the chin. If viewed from the side, the upper lip should be located behind the line from the nose to the lower edge of the chin, then there will be a sense of coordination, and it will not look good if it is insufficient or too much. Many people have the problem that the chin is too short and then shrinks, which will not only affect the appearance, but also give people a feeling of weakness, flirtation or weakness, and will also affect their old age. Therefore, they will seek plastic surgery to help rebuild the outline of the chin. Chin plastic's common fault is that his chin is backward, short and overdeveloped. We should modify his curve to meet the above aesthetic standards as much as possible. At present, in chin pad surgery, prosthesis is the main method, and swelling and silica gel are commonly used. According to your situation, chin plastic's plan is different. Chin plastic's plan 1: that is, if this is the case for beauty seekers, not only the mandible leans forward, but also the dentition has problems, so we should correct it through so-called orthognathic surgery to restore normal dentition occlusion and normal mandibular position.
