ANA MARIA CRISTINA TANCU, MIHAELA PANTEA, ALEXANDRA TOTAN*, MIHAELA TANASE, MARINA IMRE 3D PRINTED DENTAL MODELS A COMPARATIVE ANALYSIS The aim of this study is to compare two different methods used for obtaining printed dental models -intraoral scanning and extraoral scanning; the comparative analysis was made in correlation to the accuracy of the traditional plaster cast model. Nine dental models were obtained: three plaster cast ones, three printed after intraoral scanning and there printed after impression scanning. A total of 137 measurements (arch and tooth measurements) were done on the three types of models and a statistical evaluation was performed (t-test, Fisher Test). Our results highlighted that 3D printed dental models represent a reliable option for clinical application.
