3D Printing Orientation and Film Thickness for Maxillary Complete Dentures
Sponsor: Tanta University
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
0° 3D-Printed Maxillary Complete Denture
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.
45° 3D-Printed Maxillary Complete Denture
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.
90° 3D-Printed Maxillary Complete Denture
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.
