Attachment members with internally located radiopaque information markers for CT scan

An attachment member for mating with a dental implant, comprising:

• a non-rotational structure configured to mate with a corresponding non-rotational feature of the dental implant, the non-rotational structure defining a first screw access through bore;
• a body extending from the non-rotational structure and defining a second screw access through bore extending though the entire body, the body having a first body portion and a second body portion, the first body portion having a first top surface defining at least one first recess, the second body portion having a bottom surface defining at least one second recess that corresponds to the at least one first recess in the first body portion to form a radiopaque marker cavity, the second body portion having an exterior top surface that is exposed through the gingival tissue;
• at least one radiopaque information marker located within the radiopaque marker cavity internal to an exterior side surface of the first and second body portions and the exterior top surface of the second body portion, the at least one radiopaque information marker indicating information regarding the dental implant that is revealed in response to a scan from a computerized tomography (CT) scanner;
• and
• a screw configured to extend through the first screw access through bore and the second screw access through bore to couple the non-rotational structure and the body to the dental implant.
