Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Group I: The duplication of a refitted complete removable denture will be performed using the conventional heat-cured technique.
Group II: The refitted complete denture will be duplicated using a 3D-printed CAD/CAM technique, where the denture base will be printed separately with pink resin, and the teeth will be printed as a single unit in tooth-colored resin, followed by assembly of the two components.
Group III: The refitted complete denture will be duplicated using a 3D-printed CAD/CAM technique, with the entire denture printed as a single unit in tooth-colored resin, and the denture flange veneered with pink resin.
Outcomes will be evaluated by measuring denture retention with a digital force gauge and occlusal force distribution using the T-Scan system. The collected data will be recorded, tabulated, and subjected to statistical analysis using appropriate tests for group comparisons.
