Why it matters for dental

Prosthodontists, restorative dentists, and laboratory technicians now have evidence that occlusal-plane inclination and the choice of digital camera can measurably alter the accuracy of maxillary cast transfer to a virtual articulator, directly affecting the fit and occlusal precision of crowns, bridges, and full-arch prostheses.

Key points

  • The study, published online 29 September 2026 in The Journal of Prosthetic Dentistry, quantifies how different occlusal-plane inclinations and digital camera systems influence the accuracy of digital cast mounting.
  • Accurate maxillary cast transfer is a foundational step for any case requiring occlusal harmony; deviations can produce high spots, non-working interferences, or premature contacts that require chairside adjustment or remake.
  • Clinics relying on intra-oral scanners and virtual articulators for same-day or lab-fabricated restorations should audit their current camera hardware and mounting protocols against the accuracy thresholds reported in this paper.
  • Specialists performing complex prosthodontic rehabilitations (full-arch, implant-supported, or esthetic cases) should incorporate camera-specific calibration routines to reduce cumulative digital-workflow error.
