Overdenture and dental implant framework

A dental prosthesis for restoring the appearance and function of a patient's missing teeth comprising an overdenture, a dental implant framework and a series of implants and abutments adapted to be placed within a patient's mouth, wherein the dental implant framework is intended to mate to the series of implants and abutments wherein the design of the overdenture and dental implant framework are based upon digital data comprising the appropriate tooth contours, gingiva contours, and the placement of the plurality of implants and abutments, said data being obtained from the patient's mouth:

• the dental implant framework further comprising a plurality of fittings to mate with the corresponding plurality of implants and abutments in the patient's mouth;
• wherein the position of the plurality of fittings has been determined through the use of digital data identifying the location of the plurality of implants and abutments in the patient's mouth;
• the dental implant framework further comprising a plurality of bridging structures attaching the plurality of fittings to one another;
• the design of the overdenture and dental implant framework being determined from digital data from the patient's mouth defining the appropriate tooth contours, gingiva contours and implant and abutment locations for the dental prosthesis;
• the overdenture further comprising a plurality of tooth and gingiva contours as defined by digital data obtained from the patient's mouth;
• wherein the overdenture consists of a monolithic design wherein the tooth and gingiva contours are included in the same body;
• the dental implant framework further comprising a plurality of retention features for retaining the overdenture;
• the overdenture being able to be removed from the dental implant framework and the plurality of retention features by the patient or doctor;
• the overdenture further comprising an overdenture mating surface for mating with the dental implant framework;
• and
• wherein the overdenture mating surface is created on the basis of a plurality of unique subtract bodies, wherein the plurality of unique subtract bodies is defined as at least one subtract body for mating with the dental implant framework.
