Influence of angle of printing on fracture resistance of three-dimensional printed occlusal devices compared to conventional and milled resins : a comparative in-vitro study

Description :

Milled resins exhibited superior properties compared to 3D-printed resins in terms of fracture resistance when printing angle was not considered. These characteristics play a crucial role in the durability and overall effectiveness of the treatment. Given that acrylic resin is affected by anisotropy, this study seeks to address the following research question: "How does printing angle influence the fracture resistance of resin used for occlusal devices? When angle of printing varies, how do 3D printed occlusal device resin compare to milled and conventional resins in terms of fracture resistance ?” Samples will be fabricated using three different methods: milling, conventional self-curing, and 3D printing. For the 3D-printed samples, variations in printing angle (0°, 45°, and 90°) will be introduced based on literature recommendations and common clinical practices. The samples will undergo mechanical testing to evaluate one key property: fracture resistance. The results will be analyzed to assess the influence of fabrication method and printing parameters on the mechanical performance of the resin.
