Why it matters for dental

In-vitro study shows scan-body extension design significantly affects accuracy of full-arch digital implant impressions.

Key points

  • Certain extension geometries produced statistically significant angular and linear deviations exceeding clinical thresholds for passive fit.
  • Shorter or asymmetric extensions improved both trueness and scanning time, lowering chairside adjustments and potential remake costs.
  • No scan body design eliminated the need for verification; clinicians should still cross-check full-arch scans with a conventional index or photogrammetry.
  • DSOs and high-volume implant practices may standardize scan body selection protocols to reduce variability across multiple surgeons and scanners.
