Overview
Brief 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.

Outcomes
Primary Outcomes
Retention of maxillary denture using digital force meter
Time Frame: At the delivery appointment for each denture at an average of 2.5 week from the start of denture fabrication and at 8th week (+/- 3 days)
Three readings will be taken for each maxillary denture using digital force meter, and an average will be calculated in units for Newton (N) or Kg.m/s2.
Secondary Outcomes
- Denture satisfaction using the Denture Satisfaction (DS) questionnaire.(At 2 months)
- Patient satisfaction with impression methods via the Burdens in Dental Impression-Making Questionnaire (BiDIM-Q)(At the delivery appointment for each denture at an average of 2.5 week from the start of denture fabrication and at 8th week (+/- 3 days))
