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.

Abstract

Vertical build orientation (90°) provided superior accuracy compared with horizontal orientation (0°). Both orientations produced acceptable guides (< 250 µm deviation), but vertical orientation improved accuracy by 40-110 µm. The molar region exhibited the greatest deviations.
