Why it matters for dental
Specialists and owners evaluating digital workflows for implant cases should note that digital impressions for angulated implants may introduce clinically significant error compared with conventional methods, potentially affecting prosthetic fit and long-term outcomes.
Key points
- In vitro study directly compared conventional polyvinyl siloxane impressions versus intraoral scanner impressions on implants placed at varying angulations.
- Results quantify the magnitude of linear and angular deviation between the two techniques for each angulation tested.
- Findings are most relevant to single- and multi-unit implant restorations where angulation exceeds 15° from vertical.
- Specialists and DSOs integrating fully digital workflows should consider selective use of conventional verification jigs or hybrid protocols for high-angle cases.
