At Portland Perio Implant Center, we are committed to utilizing the most advanced technology to deliver predictable and long-lasting results in full-arch implant therapy. As the field of implant dentistry continues to evolve, the shift from analog to digital workflows has transformed how we plan and execute All On 4 (AO4) and All On X (AOX) treatments. One of the most important advancements in this area is the integration of photogrammetry—a digital technique that significantly enhances the accuracy and efficiency of full-arch restorations.
Analog vs. Digital Impressions in Full-Arch Implantology
Traditionally, analog impressions using splinted open-tray techniques have been the gold standard for capturing the implant position in full-arch cases. While effective, these methods are time-consuming, technique-sensitive, and uncomfortable for patients—especially those with gag reflexes or limited mouth opening. Errors can arise from material distortion, improper splinting, or movement during set time, leading to inaccuracies that may compromise the passive fit of the final prosthesis.
The introduction of digital impression techniques—especially intraoral scanning—has provided an alternative to conventional impressions. However, conventional intraoral scanning with standard scan bodies lacks the precision needed to ensure a passive fit over multiple implants in full-arch implant therapy. In edentulous cases, errors can accumulate due to stitching artifacts, angulated implants, and limited soft tissue landmarks.
This is where photogrammetry becomes a game changer.
What Is Photogrammetry?
Photogrammetry is a digital technique that uses multiple images taken from different angles to calculate the precise 3D position of implants in the mouth. Unlike traditional intraoral scanners, photogrammetry does not rely on stitching images together over a wide arch, significantly reducing distortion.
Using special high-precision scan flags (encoded abutments) and a dedicated photogrammetry camera system, such as the PIC system or Icam4D, or an intraoral scanning photogrammetry system such as the Shinning 3D, we can achieve a trueness and precision range as low as 4–10 microns. This level of accuracy far surpasses what is achievable with conventional scanning methods, which can have deviations exceeding 50 microns or more in full-arch situations.
Advantages of Photogrammetry in All On 4 and All On X Dental Implants
At Portland Perio Implant Center, we incorporate cutting-edge photogrammetry into our digital workflow for all full-arch implant treatments. Here’s how this technology benefits our patients and referring dentists:
Elevating Full-Arch Care with Photogrammetry
Incorporating photogrammetry into AO4 and AOX treatments reflects our commitment to precision, innovation, and patient-centered care. As full-arch restorations continue to demand the highest levels of accuracy, photogrammetry ensures that we deliver results that are not only functional and esthetic but also biologically sound and long-lasting.
If you’re a restorative dentist seeking a reliable surgical partner for full-arch implant cases—or a patient interested in a fixed solution for missing teeth — Portland Perio Implant Center offers state-of-the-art technology and decades of clinical expertise to support you every step of the way.
