Abstract
Abstract A chin implant molded of biologically inert material is surgically inserted and positioned on the outer surface of the mandible to form a build-up of the jaw. The surgical procedure is called a menoplasty. The implant is designed to give a natural contour to the shape of the jaw for patients who have receding chins. The implant has two notches on its upper edge which are adjacent to the mental foramens. The notches allow for physical clearance between the mental nerves and the implant.
