1. A method of manufacturing a patient-specific prosthesis, the method comprising:
acquiring scan data, via a computer system, 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, the attachment member having a body and at least two radiopaque information markers within respective radiopaque marker cavities positioned within the body at locations internal to an exterior side surface and underneath a top surface of the attachment member, the at least two radiopaque information markers being substantially equidistant from a central axis of the attachment member, the at least two radiopaque information markers configured to indicate information regarding the dental implant;
creating, via the computer system, a three-dimensional computer model from the scan data;
based on the information indicated from the at least two radiopaque information markers, modifying, via the computer system, the three-dimensional computer model to create a modified three-dimensional computer model;
designing, 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;
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 exterior side surface and the 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 exterior side surface and the top surface of the cap portion.
