Comparing Impression Techniques for Maxillary Complete Denture Retention
Sponsor: Aga Khan University
Summary
The primary objective of this protocol is to compare retention in maxillary complete dentures using single-versus two-step Poly-vinyl Siloxane (PVS) impressions in edentulous patients at denture delivery. Secondary objectives include assessing patient satisfaction with impression methods and denture satisfaction after a two-month adaptation and comparing post-delivery adjustment visits.
