Study: NCT06599294

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: Digital scanning
Description: . For each patient three digital files will be obtained: One reference scan, one conventional IOS scan, and one IPS scan. All the STL files will be imported to dental CAD software, and scan bodies will be converted to implant multi-unit ti-base using a digital library. The updated STL files will be imported to inspection software Mimics for trueness assessments. The three-dimensional discrepancy between 2 STL files will be evaluated in terms of linear and angular deviation. A central point \&amp; central axis of the virtual MUA ti-base was used for deviation measurements. Linear deviations will be assessed for each MUA tibase on the three-space axis (X longitudinal, Y lateral, and Z vertical) using the center of the ti-base heads for the deviation measurement. Angular deviations were assessed as the angles formed by the two lines passing perpendicularly through the centers of the test image and the reference image of each ti-base.
