Accurate transfer of implant positions is critical for achieving passive fit in full-arch implant-supported prostheses. Photogrammetry has emerged as a promising digital impression technique, offering superior accuracy by eliminating cumulative stitching errors inherent to intraoral scanning. This narrative review synthesizes current evidence on photogrammetry technologies for full-arch implant rehabilitation, comparing accuracy, workflow efficiency, clinical outcomes, and limitations against conventional and intraoral scanning methods. Electronic searches of PubMed, Scopus, and Web of Science were conducted (2015-2026). Photogrammetry systems demonstrate significantly superior trueness (10-50 µm) and precision (4-18 µm) compared to intraoral scanning (trueness up to 731.7 µm in full-arch applications). A 2025 meta-analysis confirmed photogrammetry's superior trueness in distance deviation (p = .001) and angular deviation (p = .02). Intraoral photogrammetry achieves comparable accuracy to extraoral systems while capturing soft tissue in a unified scan. Navigated photogrammetry enables conversion-less provisional fabrication. While equipment costs and learning curves remain barriers, emerging smartphone-based systems promise broader accessibility. Photogrammetry represents the most accurate digital method for full-arch implant position capture, with emerging intraoral and navigated systems addressing workflow limitations.
