Summary & scoring by The Bell Brief (Dr. Jennifer Bell) using the Drill-Down Protocol (Drill-Down Score) — not the original publisher.
Why it matters for dental
Specialists placing or restoring full-arch implant cases can achieve tighter linear and angular accuracy with a metallic ring-based splinted scan protocol than with conventional scan bodies, potentially reducing framework misfit and remake risk.
Key points
- A completely edentulous arch with six implants was scanned twenty times with each protocol: conventional scan bodies and a customized metallic ring-based calibrated framework.
- The metallic ring-based calibrated framework produced mean linear deviation of 0.034 mm versus 0.124 mm for conventional scan bodies (p < 0.01).
- Mean angular deviation measured 0.31 degrees with the metallic ring-based framework versus 0.55 degrees with conventional scan bodies (p < 0.01).
- Trueness was defined as absolute deviation from coordinate measuring machine reference data; precision was defined as variability among repeated scans.
