Abstract
A method is set forth for making a computer model of patient's jaws on the basis of digital information. Digital data about the jaws, teeth, soft tissues and artificial teeth is joined in computer space to create aesthetic and functional plans for the removal of teeth, shaping of supporting bone and placement of dental implants. Artificial teeth and pre-manufactured prosthetic devices are made and attached to the dental implants at the time of surgery. The aesthetic and functional position of artificial teeth is determined prior to surgical removal of natural teeth and the ideal position of implants and the proper form of the remaining bone are determined prior to surgery. Surgical guides used to shape bone, record occlusal orientation and position dental implants are manufactured using computer milling or layered manufacturing.
