Abstract
ABSTRACT: Statement of problem: Multiple studies have analyzed the accuracy of digital scanners impressions in comparison to conventional impressions. Other studies compared the accuracy between partial and complete arch for different scanners. But little studies have analyzed the accuracy of digital scanners impressions for complete arch and single tooth. Purpose: The purpose of this study to compare the accuracy of various IOS (trueness, precision) for multiple and single prepared teeth. Material and methods: A typodont model was used. All ceramic full coverage preparation will be made on acrylic teeth representing 5 upper teeth with preparation depth1.5 mm and two wall angulation 6º with 1mm deep chamfer finish line. The model was reference-scanned with a highly accurate Desktop scanner (InEos X5), and scanned with 3 IOS Bluecam, Omnicam and Primescan (for complete arch and single tooth). This scans were cropped for 3D Compare Analysis (Geomagic). Accuracy was visualized , and descriptive analysis was performed. Results: For complete arch significant difference was noted between Primescan and (Omnicam, bluecam). Primescan had the highest accuracy followed by Omnicam and Bluecam. For single tooth significant difference was noted between (Primescan, Bluecam) and Omnicam. Primescan had the highest accuracy followed by Bluecam and Omnicam. Conclusions: For complete arch scanning Cerec Primescan showed more accurate results followed by CerecOmnicam followed by Cerec Bluecam. For single tooth scanning Cerec Primescan showed more accurate results followed by Cerec Bluecam followed by CerecOmnicam.
