STUDY PRECISION INTERNAL FIT OF ARTIFICIAL CROWNS TO THE CULT OF THE REFERENCE TOOTH AND THE DIMENSIONAL ACCURACY OF DIGITAL IMPRESSIONS IN THE EXPERIMENT

One of the main factors that reduce the period of use of fixed dentures is the reduction in the quality of the internal fit of the crowns to the tooth. Causes of invalid boundary clearance are different, in particular the violation of the art clinical and laboratory stages of prosthesis. Feature of orthopedic treatment is that the prosthesis is not a doctor, and a dental technician in the laboratory. In this link a doctor's office and laboratory is the impression prosthetic bed. One of the latest modern methods of obtaining the impression is the system volume intraoral scanning, allowing obtaining digital prints. The aim of this study was to study the internal fit of artificial crowns made on digital impressions obtained with intraoral scanner.
