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.
Completely edentulous patients with good local and systemic health.
Patients age ranging from 50 to 70 years old.
Patients with adequate inter-arch space.
Patients with good neuromuscular control.
Patients with any oral diseases which may affect denture construction
Patients with oral parafunctional habits.
Patients with tempro-mandibular disorders
