Accuracy of Digital Impressions and Fitness of Single Crowns Based on Digital Impressions
In this study, the accuracy (precision and trueness) of digital impressions and the fitness of single crowns manufactured based on digital impressions were evaluated. #14-17 epoxy resin dentitions were made, while full-crown preparations of extracted natural teeth were embedded at #16. (1) To assess precision, deviations among repeated scan models made by intraoral scanner TRIOS and MHT and mod...
متن کاملCAD/CAM and Digital Impressions
Currently, two genres of CAD/CAM systems exist. One is used only in-office, while the other genre is a combination of in-office scanning and image transmission and milling of restorations or pouring of models in the laboratory. All systems start with scanning of the preparation, the method depending on the specific system. CAD/CAM systems have developed considerably, offering accuracy and more ...
متن کاملAccuracy of intraoral digital impressions using an artificial landmark.
STATEMENT OF PROBLEM Intraoral scanners have been reported to have limited accuracy in edentulous areas. Large amounts of mobile tissue and the lack of obvious anatomic landmarks make it difficult to acquire a precise digital impression of an edentulous area with an intraoral scanner. PURPOSE The purpose of this in vitro study was to determine the effect of an artificial landmark on a long ed...
متن کاملAccuracy of Digital Impressions Achieved from Five Different Digital Impression Systems
Dr. Duret first introduced the CAD/CAM concept to dentistry in 1973 in Lyon, France in his thesis entitled Empreinte Optique, which translates to Optical Impression. The concept of CAD/CAM systems was further developed by Dr. Mormann, a Swiss Dentist, and Mr. Brandestini, who was an electrical engineer. 8 CEREC was the first commercially available digital impression system for use in the field ...
متن کاملClinical Acceptability of the Internal Gap of CAD/CAM PD-AG Crowns Using Intraoral Digital Impressions
The purpose of this study was to compare the internal gap between CAD/CAM palladium-silver crowns and cast gold crowns generated from intraoral digital versus conventional impressions and to determine the clinical acceptability. Nickel-chrome master dies were made from the prepared resin tooth with the conventional impression method (n = 40). For ICC (Intraoral, CAD/CAM) group, 10 intraoral dig...
