Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* 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.
