A comparative analysis of the passivity of fit of complete arch implant-supported frameworks fabricated using different acquisition techniques.

Statement Of Problem: The accuracy of intraoral scanners (IOSs) in recording edentulous jaws has improved recently. However, improvement in accuracy does not necessarily imply the clinical validity of the scans, and limited information is available regarding the manufacture of passively fitting prostheses.

Purpose: The purpose of this in vitro study was to analyze the passivity of complete arch screw-retained frameworks fabricated using different acquisition techniques.
