A full set of facial photographs are required to determine being a candidate for a chin implant, due to the fact that the chin and the implants are both three-dimensional structures. The primary goal of a chin implant is to bring the chin forward. The secondary goal is to give added width to the chin area and the third injury minor goal is to give a small amount of vertical height. Chin implants are manufactured in a large array of shapes and sizes, are composed of Silastic, and are usually placed through small incisions underneath the chin as an outpatient surgical procedure.
