ABSTRACT:
An extended implant is surgically inserted underneath the soft tissue and superposed on the human mandible. The implant has a convex anterior surface. The posterior surface has a concave surface for cooperating with the irregular bony surface of the mandible. The medial sagittal area of the convex surface has a protuberance for augmenting and providing a natually appearing chin contour when the implant is in place. The implant extends and tapers bilaterally from the protuberance. The superior edge has bilateral arcuate-shaped depressions for avoiding the mental nerves. The snug fit of the implant against the mandible prevents movement thereby precluding bone erosion below the lower teeth. The snug fit and the arcuate depressions preclude painful impingement of the mental nerves.
