Description
Mahnaz Arshad and three colleagues test how print angle affects temporary three-tooth bridges from a light-based printer in a 2026 study. Bridges were printed at several tilt angles along two axes, twelve per group. A profilometer measured surface roughness, and a universal machine broke samples to find fracture load. Both printing directions shaped the results clearly.
The smoothest surfaces came from one tilt paired with a steep sideways angle. The strongest bridges shared that same tilt but paired it with no sideways angle. Where on the bridge the roughness was measured made no clear difference. The best angle thus depends on the goal: smoothness for comfort and looks, zero sideways tilt for strength. Clinics can tune printing to the case.
