Brief summary
Twenty completely edentulous patients with old, removable dentures with ill-fitting maxillary dentures, proper vertical dimension, and proper occlusion will be recruited for this trial. They will be rehabilitated with duplicated complete dentures manufactured by conventional and two different 3D-printed CAD-CAM Complete Removable Dentures techniques. Outcomes will be evaluated, including denture retention, which will be evaluated using a digital force gauge, and occlusal force distribution by using a t-scan.
Detailed description
The study will be conducted at the outpatient clinic of the Oral and Maxillofacial Prosthodontics Department, Faculty of Dentistry, Ain Shams University. This within-subject controlled clinical trial will involve twenty completely edentulous patients with old, ill-fitting maxillary complete dentures, who will be selected and recruited following approval by the Research Ethics Committee of the Faculty of Dentistry, Ain Shams University (FDASU-REC). These patients will be rehabilitated with duplicated complete dentures produced through conventional methods and two distinct 3D-printed CAD/CAM techniques. 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.
Interventions
DEVICEDuplicated refitted complete denture made from conventionally heat-cured polymethyl methacrylate.
The duplication of a refitted complete removable denture will be performed using conventional heat-cured polymethyl methacrylate through the conventional heat-cured polymerization technique.
DEVICEDuplicated refitted complete denture made from 3D-printed CAD/CAM pink polymethylmethacrylate acrylic resin.
The duplication of a refitted complete removable denture will be performed using a 3D-printed CAD/CAM technique, where the denture base is printed separately with pink polymethyl methacrylate resin, and the teeth are printed as a single unit using tooth-colored resin, followed by the assembly of the two components.
DEVICEDuplicated refitted complete denture made from 3D-printed CAD/CAM white polymethylmethacrylate acrylic resin.
The duplication of a refitted complete removable denture will be performed using a 3D-printed CAD/CAM technique, where the denture base is printed as a single unit using tooth-colored resin, and the denture flange will be veneered with pink polymethyl methacrylate resin.
