Accuracy of Digital vs Conventional Denture Impressions: An In Vivo Study

The goal of this clinical trial is to compare the accuracy of two denture impression techniques, digital intraoral scanning and conventional border-molded impressions, in adults who have lost all their teeth (fully edentulous patients). The main questions it aims to answer are: Is a digital intraoral scan as accurate as a conventional impression for capturing the shape of the mouth, including movable gum areas? Are repeated digital scans consistent (precise) when taken multiple times on the same patient? Researchers will compare digital impressions taken with an intraoral scanner to conventional impressions made with custom trays and border molding to see if digital scans can match the accuracy of the traditional "gold standard" method. Participants will: Attend Dubai Dental Hospital for two study visits. Have their mouth scanned three times using a digital intraoral scanner. Have a conventional impression taken using a custom tray and high-accuracy material after border molding. Provide informed consent and allow their impression data to be analyzed for accuracy.
