Summary
In vivo prospective clinical study will be designed, 12 participants will be included. After intraoral scanning, a conventional impression is made for each patient. The groups will be compared for accuracy.
Detailed description
* Recruit 12 eligible edentulous patients * Scanning Process: Perform five intraoral scans (IOS) of the maxillary flabby ridges for each patient. . WTI: perform five WTI for each patient * STL Export: Export scans and corresponding cast scans obtained via the Window Technique Impression (WTI) as STL files using the intraoral scanner software. * 3D Distance Measurement: Import IOS and cast STL files into Geomagic Wrap 2017 for a two-phase best-fit alignment, using the Cast scan as the reference for evaluating trueness and precision. * Comparison of Scans: * Compare the IOS scan and corresponding cast scan obtained via the Window Technique Impression (WTI) to calculate trueness -compare WTI and corresponding cast scan obtained via the Window Technique Impression (WTI) to calculate trueness- * Compare each of the five IOS impressions by using each scan as a reference against the others to calculate precision. * Compare each of the five WTI impressions by using each scan as a reference against the others to calculate precision. • Deviation Analysis: Generate a color difference map of each superimposition for visual analysis of deviation patterns.
