Abstract

Purpose: The purpose of this study was to compare data acquisition using two different intraoral scanners in the same maxillectomy patients.
Materials and Methods: Maxillectomy defects and dentate maxillary arches of 6 patients were scanned by TRIOS 3 and Trophy 3DI PRO. Areas of 3-dimensional (3D) data were calculated using 3D analysis software. Acquired polygon areas were tested for significant differences between the scanners.
Results: Scans captured residual teeth in most patients, but not entire maxillectomy defects. The areas of 3D data significantly differed between the scanners (P<0.05).
Conclusion: More scanning data were acquired in all cases by TRIOS 3 than by Trophy 3DI PRO. However, neither scanner could acquire complete maxillary defect data.
