Abstract
Abstract A complete dental implant system and method uses a standard shape if both the healing abutment, the impression coping and in the final tooth prosthesis. A series of four to five standard shapes which will oppose the gum tissue will be used for different types of teeth, and to enable control over the size and shape of material will be introduced into the patient's tissue, for a single tooth replacement beginning at the time the gums above the threaded bone penetrating implant are opened and the healing around the pre-specified shape is started. This causes the supporting adjacent tissues to have to heal but once. The impression coping and healing abutment which have the same shape facilitate the non-damaging insertion and removal from the gum area and eliminate the need for extensive work on the implant tooth prosthesis while it is within the patient's oral cavity. The system enables less work to be done on the prosthesis while the patient is in the chair, and thus more control at the dental lab. Three alternatives are disclosed for forming the final tooth prosthesis, including (1) formation of the prosthesis over coping having a shape specified collar, (2) beginning with a titanium blank, and (3) beginning with a titanium rough preparation.
