Trueness of Full Arch Scans and Generated Digital Implant Models

"Nine conventional physical open tray impressions will be poured into a hard dental stone to obtain nine definitive implant casts with conventional implant analogs to act as a reference comparator.~Impressions will be digitized to reference STL files."

Nine optical impressions will be obtained while additional geometric scanning aids are coupled with the scan bodies to get nine CAD/CAM 3D-printed polymer casts with digital implant analogs.

The nine STL files of optical scanning will serve as reference data for comparison with the digitized DIMs to evaluate the accuracy of representation of the actual position of implants in the software.
