Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* The trueness of full arch digital scans when additional geometric scanning aids are coupled with the scan bodies.
* The trueness of the generated 3D-printed DIMs.
Participants will provide two types of impressions to compare after osteointegration; the first will be conventional open tray impression used as a gold standard comparator, the second will be digital scans with additional geometric scanning aids coupled with the scan bodies.
Accordingly generated 3D-printed DIMs will be printed and compared to the digital image to evaluate its accuracy.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
conventional physical impressions
Nine physical open tray impressions will be poured into a hard dental stone to obtain nine definitive implant casts with conventional implant analogs.
The impressions will be scanned to provide a gold standard reference STL files.
conventional impression stone casts digitization
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.
optical impressions with additional geometric scanning aids coupled with the scan bodies
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.
digital scanning with coupled scanning aiding device
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.
Digital Implant Model assessment of accuracy
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.
