Abstract:
1. A method of manufacturing a dental prosthesis comprising a tooth prosthesis for implantation into a jawbone cavity of a pre-identified patient, the tooth prosthesis comprising a root portion, an occlusally facing portion, and a custom crown portion as an integral part of the tooth prosthesis prior to integrating the tooth prosthesis into an embedding portion of the jawbone cavity of the pre-identified patient, the crown portion comprising or integrated with the occlusally facing portion, the method comprising the steps of: receiving imaging data describing a three-dimensional shape of an outer surface portion of a root portion of a nonfunctional natural tooth of the pre-identified patient, deriving digital design data defining a three-dimensional shape of an outer surface of a root portion of the tooth prosthesis responsive to the received imaging data, and a three-dimensional shape of an outer surface of an occlusally facing interface of the root portion of the tooth prosthesis to receive the occlusally facing portion of the tooth prosthesis, manufacturing the root portion of the tooth prosthesis at least partially responsive to the digital design data to form at least a substantial portion of the root portion of the tooth prosthesis, to include shaping at least a substantial portion of the outer surface portion of the root portion of the tooth prosthesis to conform with and to substantially dimensionally match the three-dimensional shape of the outer surface of the root portion of the tooth prosthesis derived from the three-dimensional shape of the corresponding outer surface portion of the root portion of the nonfunctional natural tooth, so that the entire outer surface portion of the root portion of the tooth prosthesis that corresponds to an entire embedding jaw bone cavity surface associated with the nonfunctional natural tooth of the pre-identified patient is sized and shaped so as to not exceed dimensionally a natural pre-insertion three-dimensional shape of the respective embedding jaw bone cavity surface when the tooth prosthesis is clinically positioned therein; and manufacturing a custom-shaped dental splint configured to provide temporary primary stability to the tooth prosthesis in a final geometrical relation to the embedding portion of the jawbone cavity of the pre-identified patient, to include the steps of:
