This randomized crossover clinical trial aims to evaluate the effect of different three-dimensional (3D) printing orientations and layer thicknesses on the trueness, dimensional accuracy, and patient satisfaction of maxillary complete dentures in completely edentulous patients. Each participant will receive two maxillary 3D-printed complete dentures fabricated using the same printing orientation (0°, 45°, or 90°) with two different layer thicknesses (50 μm and 100 μm) in a crossover sequence. The study will compare the influence of these printing parameters on denture accuracy and patient-reported outcomes to identify the optimal 3D printing settings for complete denture fabrication.

Participants will receive two maxillary complete dentures fabricated using a 0° 3D printing orientation. One denture will be printed with a 50 μm layer thickness and the other with a 100 μm layer thickness. Participants will wear each denture for three months in a crossover sequence to evaluate trueness, dimensional deviation, and patient satisfaction.
