Precision and Trueness of Computerized Optical Impressions in Maxillectomy Defects: An In Vitro 3D Comparison

To evaluate the precision and trueness of computerized optical impressions of maxillectomy defects.Three different maxillectomy defect models based on the Aramany classification system were used. Reference digitization of the models was performed with an industrial computerized tomography scanner. Each model was scanned five times using an intraoral scanner (True Definition). With the use of 3D evaluation software, the 3D datasets were...
