Apparatus for facilitating acquisition of a scan and intraoral scanning procedures

A scan gauge for facilitating acquisition of a scan during an intraoral scanning procedure in a patient's mouth, comprising:

• an elongate body having an upper surface, a lower surface, and a plurality of side walls extending between peripheral edges of the upper surface and peripheral edges of the lower surface, wherein one or more of the plurality of side walls slope outwardly from the upper surface to the lower surface of the elongate body so that the upper surface and the one or more sloped side walls are observable in an intraoral scan when the scan gauge is scanned from substantially above and perpendicular to the upper surface;
• and
• an attachment portion arranged on a lower surface of the elongate body, whereby the elongate body extends substantially perpendicular to a longitudinal axis of the attachment portion, and is configured to receive a fastening element to attach the elongate body to an implant or to an intermediate component in the patient's mouth,
• wherein one or more of the plurality of side walls include at least one cut-out portion configured to enable an intraoral scanner to retrieve data from a surface of the attachment portion when the scan gauge is scanned from substantially above and perpendicular to the upper surface of the elongate body, and
• wherein the elongate body comprises one or more identifier markings on the upper surface of the elongate body or on one or more of the sloped side walls, or on both the upper surface and on one or more of the sloped side walls, wherein the identifier markings are arranged to be observable in an intraoral scan when the scan gauge is scanned from substantially above and perpendicular to the upper surface of the elongate body to provide dimensional information, tolerance information, or both dimensional and tolerance information for the elongate body.
