Abstract A reliable novel technique for superimposing intraoral and face digital scan without using any aligner or scan abutment is presented. This technique involves scanning the perioral area by incorporating parts of the upper dental arch into the perioral tissue scan. Unlike other proposed methods, including the upper dental arch scan in the perioral tissues scan, ensure accurate spatial positioning of intraoral dental arches scans within the facial scan.
