Claim 13:
14. A method of manufacturing a patient-specific prosthesis, the method comprising:
receiving, via a computer system, attachment member data;
receiving, via the computer system, scan data of a patient's mouth including at least gingival tissue and an attachment member coupled to a dental implant installed in the patient's mouth when the attachment member is installed in the patient's mouth, wherein the attachment member has a body with an integrated supragingival portion and subgingival portion, the integrated supragingival portion and subgingival portion being operable to receive a fastener to couple the attachment member to the dental implant, the subgingival portion being insertable into the dental implant, the attachment member including at least two radiopaque information markers within respective radiopaque marker cavities positioned within the body at locations internal to an outermost exterior side surface and underneath an outermost top surface of the attachment member, wherein at least one radiopaque information marker of the at least two radiopaque information markers indicates a location of a central axis of the attachment member in the scan data;
based on information indicated from the attachment member data and the scan data of the at least two radiopaque information markers, modifying, via the computer system, a three-dimensional computer model of the attachment member to create a modified three-dimensional computer model;
providing, via the computer system, a three-dimensional computer model of at least a portion of the patient-specific prosthesis using the modified three-dimensional computer model,
wherein the providing of the three-dimensional computer model of the at least a portion of the patient-specific prosthesis improves restorative flexibility during design and installation of the patient-specific prosthesis; and
attaching the attachment member to the dental implant installed in the patient's mouth, wherein attaching the attachment member to the dental implant installed in the patient's mouth comprises:
inserting a fastener through an insert portion of the attachment member,
engaging the dental implant with the fastener, and
removably connecting a cap portion of the attachment member to the insert portion, wherein the cap portion of the attachment member includes the outermost exterior side surface and the outermost top surface of the attachment member, and wherein the at least two radiopaque information markers are located within a space defined at least in part by the outermost exterior side surface and the outermost top surface of the cap portion.
