Why it matters for dental
Dental labs and prosthodontic teams that rely on facial scanning for smile-design or full-arch prostheses may see clinically relevant errors in the true horizontal plane if patient head position or scanner angle deviates from protocol; the study quantifies those errors.
Key points
- Peer-reviewed study published in The Journal of Prosthetic Dentistry (online 7 Oct 2026) by Revilla-León et al.
- Measured impact of head tilt and facial-scanner viewing angle on the accuracy of the true horizontal plane obtained with an app-based facial scanner.
- Findings directly apply to workflows using facial-scan data for esthetic planning, virtual articulators, and CAD/CAM restorations.
- Academia and Specialist readers (prosthodontists, lab technicians) can use the data to refine chair-side scanning protocols and reduce lab remakes.
