Why it matters for dental
Dentists adopting fully digital workflows now have the first automated method to measure the exact 3-D relationship between finish lines and the peri-sulcular soft tissues—data that can reduce open-margin risk and improve emergence-profile design.
Key points
- December 2026 Journal of Dentistry article presents an algorithm that quantifies sulcular depth and tissue thickness directly from intra-oral scans at both epi- and subgingival margins.
- Automation removes the need for manual calipers or 2-D cross-sectioning, cutting measurement time from minutes to seconds per margin.
- Authors Majed Kutaini and Sven Reich provide quantitative benchmarks for acceptable peri-sulcular dimensions that labs and clinicians can incorporate into CAD margin settings.
- Technique is limited to digital impressions; clinicians still using conventional impressions or analog workflows will not gain immediate benefit.
