Accuracy and Internal Fit of 3D printed Occlusal Splint, according to the printing position

Abstract

Understanding the importance of 3D printing strategies is a key to obtain predictable, optimized and consistent dental appliances using digital technologies. This study aims to present the influence of printing orientation on the intraoral fit of full arch coverage splints. Splints were designed for two patients using the CAD software and printed in a SLA 3D printer with different orientations (0, 30, and 90 degrees), and the internal fit was checked on patients’ mouth. Differen­ces between the fit of the splints were verified, with the worst results for 90º oriented splints, although more detailed studies are recommended by the authors.
