Comparison of Three Final Impression Techniques for Severely Resorbed Mandibular Ridges

This in vivo crossover study aims to compare the accuracy of three different final impression techniques for severely resorbed mandibular ridges in completely edentulous patients. The accuracy of the impressions will be evaluated digitally using three-dimensional scanning and deviation analysis to determine differences among the impression techniques.
