1. A milling adaptor system configured to position an abutment blank relative to a housing of a milling unit, the milling adaptor system comprising:
a holding device having opposing first and second ends, the holding device including:
a flange positioned at the first end and having a joining surface configured to engage the abutment blank, the flange also having an opposing lower surface opposing the joining surface,
a securing shaft extending from the opposing lower surface of the flange to the second end, and
an engagement bore extending longitudinally through the holding device with respect to a longitudinal axis of the securing shaft; and
a fastener having a fastener head and having a threaded shaft extending from the fastener head, the fastener configured to extend through the engagement bore and couple with the abutment blank, such that the flange is positioned between the securing shaft and the abutment blank;
wherein the securing shaft includes at least one securing surface for securing the holding device to the housing of the milling unit and wherein the flange includes at least one pin hole positioned between the engagement bore and a peripheral edge of the joining surface, the at least one pin hole configured to receive a corresponding pin that engages with the abutment blank to rotationally fix the abutment blank relative to the holding device.
