Correcting Screw-Access Angulation in a Maxillary Anterior Implant Bridge Using Photogrammetry
Summary & scoring by The Bell Brief (Dr. Jennifer Bell) using the Drill-Down Protocol (Drill-Down Score) — not the original publisher.
Why it matters for dental
A technique article demonstrates how photogrammetry can rescue an anterior implant bridge case when screw-access angulation is misaligned, giving restorative dentists and specialists a digital workflow to avoid remaking the prosthesis.
Key points
- Photogrammetry replaces traditional impression-taking to capture implant positions, allowing the lab to fabricate an angled screw channel without physical repositioning of the implant.
- The case illustrates a maxillary anterior 3-unit screw-retained bridge in which the original access trajectory would have compromised esthetics or required crown lengthening.
- Digital workflow steps include CBCT planning, intraoral scanning, and photogrammetric alignment files sent to the laboratory for a custom titanium interface.
- The method applies to both single-unit and multi-unit implant restorations where screw retention is preferred but access is compromised by implant angulation.
