Summary

The main goal of complete denture prosthodontics is to restore function, comfort, and aesthetics by replacing missing teeth and supporting structures. Flabby ridges, defined as mobile soft tissue on the alveolar ridge, pose challenges in creating stable dentures, as these tissues can displace under occlusal forces, compromising retention and support. Special impression techniques are necessary to manage flabby ridges effectively One widely accepted method is the window technique, which uses double spacers and window in the flabby tissue area. However, this technique is technically complex. This RCT aims to evaluate whether intraoral scanning (IOS) provides an alternative to the window technique for recording maxillary flabby ridges.

The hypothesis was that IOS will demonstrate superior clinical results in terms of both Retention and Patient satisfaction compared to the conventional window technique impression (WTI).
