Digital impressions were introduced in order to overcome some inconveniences related to conventional impression materials.The aim of this in vitro study is to determine and evaluate the way the abutment geometry influences the accuracy of both, digital and conventional impressions. Crown preparations with occlusal convergence angles (0,6,10 and 20 degrees) were created from 4 resin maxillary right incisors.Each preparation was scanned using a high resolution scanner (reference scanner) and saved in stereolithography (STL) format. Then the prepared resin teeth were scanned (PlanScan group) using an intraoral scanner and saved in STL format as well.A number of three conventional polyvinyl siloxane (PVS) impressions were made from each preparation, which were poured with Type IV dental stone and scanned using the same intraoral scanner (PVS group). All STL files were compared using metrology software (Geomagic Studio 2013), in terms of trueness and precision. Based on the findings in this study, it may be concluded that the accuracy of digital impressions is superior to conventional methods, but the difference between them is not significant.
