Impact of Build Orientation on the Dimensional Accuracy of DLP-Printed Implant Surgical Guides: An In Vitro Study

Key Points

• This study aims to evaluate how different build orientations affect the dimensional accuracy of DLP-printed surgical guides.
• Compared vertical (90°) and horizontal (0°) build orientations in 3D printing.
• Measured deviations in printed surgical guides.
• Assessed accuracy based on mean deviation less than 250 µm.
• Vertical orientation resulted in 40-110 µm greater accuracy than horizontal orientation.
• Both orientations produced acceptable guides with deviations under 250 µm.
• The molar region showed the highest deviations in both orientations.
