15 Patients requiring complete dentures will be recruited from Dubai Health. Each patient will receive two sets of dentures with a washout period between sets. Patients will remain blinded to the fabrication method used for each set.
* Group 1: Participants will first receive conventionally fabricated dentures for both the upper and lower jaws. This set will be made using traditional techniques, including impressions, a custom tray, jaw relation recording, try-in, and final fitting. After the washout period, they will receive a second set created with the 3D-printed technique. * Group 2: Participants in this group will initially receive 3D-printed complete dentures through a digital workflow, which involves intraoral scanning, STL file export, digital design, design review with the patient, 3D printing, and final fitting. Following the washout period, they will then receive a conventionally fabricated set.

Crossover
Digital Occlusal Analysis Device
DeviceComputerized occlusal analysis performed using T-Scan and ModJaw devices to record occlusal contacts, timing, and force distribution during prosthesis fitting and function.
Occlusal Force Distribution and Contact Accuracy
Quantitative assessment of occlusal contact number, area, timing, and force distribution in digital versus conventional complete dentures, measured using T-Scan and ModJaw systems, and validated against articulating paper marks.
Oral Health-Related Quality of Life (OHRQoL)
Change in Oral Health Impact Profile (OHIP-14) total scores between digital and conventional dentures, reflecting impact on comfort, function, and psychosocial well-being.
Clinical Time Efficiency
Mean chairside time (in minutes) required for each clinical step, including impressions, jaw relation recording, try-in, and final insertion.
