Influence of different dental scenarios on the accuracy of computerized optical impressions: an in vitro pilot study.

Objectives: This in vitro study aimed to determine the influence of various dental scenarios on the accuracy of computerized optical impressions (COIM), specifically focusing on trueness and precision.

Materials And Methods: Eight resin casts representing different dental scenarios, including fully dentate upper (UU) and lower jaws (UL), full-arch preparation (FA), single abutment preparations (SA), anterior (AB) and lateral bridge preparations (LB), partial crown preparations (PA), and veneer preparations (VE), were digitally captured using an extraoral reference scanner and an intraoral scanner. The datasets from both scanners were superimposed to calculate and statistically evaluate three-dimensional mean deviations.
