Experimental rationale for the manufacture of ceramic inlays using an optical impression by the scanner of russian production

Abstract

The results of the experimental study are presented, in which cavities under the all-ceramic inserts of the in-ley type were prepared on 20 premolars and molars of both jaws removed medically. Optical impressions were obtained with the help of a domestic VT Dental scanner. The tabs were made using the CAD \ CAM method. After fixing the inserts, longitudinal teeth sections were made to study the accuracy of the attachment of the inserts by scanning electron microscopy. Conclusions: The tightness of the all-ceramic inlays in the cavities, which are made using the VT Dental scanner (Russia), has the same results as the best world analogues of the scanning device.
