Chin, that's chin. It plays a decisive role in the influence of facial contour. If the chin is not well developed, it will cause the chin to retreat backwards, showing a slope shape, and the mouth will be pushed forward, which often gives people a feeling of anger, and even the beak will be severely deformed, making the whole face ugly. Chin augmentation is the most direct, simple, safe and effective method to correct this deformity. Aesthetic standard of chin: chin should protrude moderately. There is an obvious depression between the lower lip and chin. There should be a clear angle between chin and neck. When the mouth is closed, the front edge of the lips is located in the line between the tip of the nose and the front edge of the chin. The function of chin augmentation: it can improve the proportional relationship between forehead, nose and chin and shape the overall aesthetic feeling of the face. It can make the protruding mouth shrink back and improve the mouth shape. Under local anesthesia, the prosthesis carved in advance according to the beauty seeker's face is placed between the bone and soft tissue of the chin through a hidden small incision (in the mouth), and the position is adjusted to sew the incision. Chin material: medical silicone rubber, expanded polytetrafluoroethylene or porous high-density polyethylene. The safety has been clinically tested and you can choose with confidence. The key to the success of chin augmentation surgery lies in the carving of the prosthesis, that is, according to the facial characteristics of each beauty seeker, designing the shape of the prosthesis suitable for him plays a decisive role in the success of the operation. Secondly, the placement of the prosthesis should be correct, that is, the prosthesis should be placed in front of the lower edge of the chin, not under the chin. Otherwise, it is easy to be self-defeating. Finally, it lies in standardized surgical operation and postoperative care.
