Accuracy assessment of intraoral scanner mounted with a novel isolation device for final impressions in fixed prosthodontics: in vivo study.

Description :

This study aims to evaluate the effect of a new saliva isolation device "ArArat" on the accuracy of digital impressions of fixed restorations, with different margin situations. As a result, the study will be conducted on 3 different patients, each presenting a lower molar to be crowned, with 3 different situations of the margin. on each patient, a reference conventional impression, 22 digital impressions without the device, and 22 digital impressions with the device will be transported to a superimposition software in order to study deviations between the different impressions and compare the accuracy of the different saliva isolation technics.
