A small or retruded chin can lead to false perceptions and effects on self-confidence and self-image. Chin advancement or chin augmentation will correct the weak chin. Chin advancement is the process of dividing the chin bone and sliding it forward through a small incision inside the mouth. Because of the bone sliding, the jaw is actually lengthened. Chin augmentation is the process of placing an implant through a small incision inside the mouth or under the chin. They both create a beautiful aesthetic result matching the chin to the overall facial aesthetics.
