3D Printing Orientation and Film Thickness for Maxillary Complete Dentures
Clinical and Laboratory Assessment of 3D Printing Orientation and Film Thickness on the Accuracy and Patient Satisfaction of Maxillary Complete Dentures

Conditions
Summary
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.

Interventions
Participants will receive maxillary complete dentures fabricated using a 0° three-dimensional (3D) printing orientation. Each participant will receive two dentures printed with 50 μm and 100 μm layer thicknesses in a crossover sequence. This intervention is intended to evaluate the effect of the 0° build orientation on denture trueness, dimensional deviation, and patient satisfaction.
Participants will receive maxillary complete dentures fabricated using a 45° three-dimensional (3D) printing orientation. Each participant will receive two dentures printed with 50 μm and 100 μm layer thicknesses in a crossover sequence. This intervention is intended to evaluate the effect of the 45° build orientation on denture trueness, dimensional deviation, and patient satisfaction.
Participants will receive maxillary complete dentures fabricated using a 90° three-dimensional (3D) printing orientation. Each participant will receive two dentures printed with 50 μm and 100 μm layer thicknesses in a crossover sequence. This intervention is intended to evaluate the effect of the 90° build orientation on denture trueness, dimensional deviation, and patient satisfaction.
