- Abstract
<bold>Purpose: </bold>The aim of this study was to evaluate the feasibility and accuracy of using an intraoral scanner to digitize edentulous maxillectomy defects.<bold>Materials and Methods: </bold>A total of 20 maxillectomy models with two defect types were digitized using cone beam computed tomography. Conventional and digital impressions were made using silicone impression material and a laboratory optical scanner as well as a chairside intraoral scanner. The 3D datasets were analyzed using 3D evaluation software.<bold>Results: </bold>Two-way analysis of variance revealed no interaction between defect types and impression methods, and the accuracy of the impression methods was significantly different (P = .0374).<bold>Conclusion: </bold>Digitizing edentulous maxillectomy defect models using a chairside intraoral scanner appears to be feasible and accurate.
