IMP158 - Navigating Implant Success with Photogrammetry: The How, When and Why-IMP158 Article

IMP158 Article

Pdf Summary

The article explains how photogrammetry is changing full-arch implant dentistry by making final impressions faster, simpler, and often more accurate than traditional analog workflows. Photogrammetry uses calibrated cameras to capture the 3D spatial positions of implants from 2D images, then transfers that data into CAD software for prosthesis design.<br /><br />The author contrasts this with older methods, which could take an entire morning or more and involve many error-prone steps such as verification jigs, multiple impressions, cast mounting, and extensive chairside/lab work. In practice, photogrammetry can reduce the appointment to about 30 minutes and shift much of the process to staff or a lab.<br /><br />The article outlines common systems, their benefits, and limitations. Advantages include reduced stitching errors, less sensitivity to saliva or movement, and faster capture of implant positions. However, photogrammetry is expensive, may not be practical for low-volume implant practices, and is model-less, which can make passivity checks and titanium-base cementation difficult. It also still requires an intraoral scan or conventional scan to capture soft tissue and remaining teeth.<br /><br />Evidence suggests photogrammetry is reliable and often comparable or superior to conventional impressions, though the literature is still limited and results vary depending on implant factors, workflows, and measurement methods. The author stresses careful evidence-based interpretation.<br /><br />Alternatives such as the Optisplint are introduced as lower-cost hybrid workflows that combine digital scanning with a physical verification jig. The article concludes that digital tools can improve efficiency, reduce lab burden, increase patient comfort, and help dentists manage more implant cases, but clinicians must still choose treatment based on patient needs rather than convenience.
