Full arch accuracy of intraoral scanners with different acquisition technologies: An in vitro study
case study
case study

Purpose

The study assessed and compared the full-arch accuracy—of five intraoral scanners (IOS), using three different acquisition technologies.

Approach

  • Used a standardized cast as recommended by ADA/ANSI 132 standard, each scanner was tested across 90 scans with three experienced operators.
  • Technologies evaluated:
    • Confocal Imaging: TRIOS5 & CS3800
    • Structured Light: Mediti700  & AlliedStar260
    • Multi-Direct Capture (MDC): iTero Lumina

Key Metrics Assessed & Findings:

  •  Trueness: Measures closeness of the scan measurements to the actual reference values.
    •  iTero Lumina (MDC) showed the lowest mean error in trueness (0.04%) outperforming all other scanners.
  • Precision: Measures consistency across repeated scans.
    • iTero Lumina (MDC) showed the lowest mean error for precision (0.032%) and highest ratio of acceptable scans (99.6%).
  • Plane Deviation: Measures vertical error from a reference plane.
    • Lumina’s mean error was lowest at 19μm, superior to other scanners, statistically significant vs CS 3800 only.
  • Inter-Operator Variability
    • iTero Lumina provided the most consistent results across operators. This could translate into reduced technique-sensitivity.

Conclusion:

  • Scanning Technology Matters:
    MDC technology (iTero Lumina) greatly improved linear accuracy (trueness and precision) in full-arch scans compared to confocal and structured-light scanners.
  • Clinical Significance:
    iTero lumina delivered the most reliable and consistent results, and may offer a more accurate, efficient and reliable digital impression solution for full-arch dentistry, though the authors emphasize the need for further research under real-world clinical conditions.
  • Future Directions:
    More research is recommended, especially for implant borne restorations in real-world.
