Grammetry™
The digital IOS full-arch solution
Imagine going for a ride in your car today and discovering that it can fly!
Seems unrealistic, right? Well, that is what Grammetry does to your IOS. Grammetry takes that already highly-functional tool, your IOS, and offers you a new and innovative utility. To fully understand the impact of Grammetry you should have a well-rounded understanding of photogrammetry.
What is dental photogrammetry?
Dental photogrammetry is the newest and hottest topic within the full-arch dental community due to its high level of implant-capture precision. This micron-level accuracy has allowed ROE to design 1,000+ arches this year (85% same-day), including coping-free, final zirconia restorations. Photogrammetry provides the precise location and angulation of placed MUA’s or implants. Overall, the inherent benefits of photogrammetry include:
Photogrammetry and Grammetry: A Full Arch Technology Review
Grammetry enables clinicians to experience all of the listed benefits of photogrammetry, and none of the unique challenges that photogrammetry presents.
ROE’s Grammetry solution addresses each of these photogrammetry challenges. In its most basic form, Grammetry allows
- The use of approved IOS scanners for implant capture,
- Provides a simple capture protocol on the day of surgery,
- Delivers the ability to fabricate physical models (not available through photogrammetry), and
- Gives the ability to manage the full workflow from surgery to final zirconia.
- Is scalable regardless of your number of operatories/locations, the number of surgeries, or preferred surgical protocol (freehand, static-, dynamic-guided, robotics, etc).
This is all possible, affordable, and available today.

Patient Case Study
Dr. Clint Metcalf completed 5 arches in 3 days with Grammetry and was kind to share images of one of the arches. Patient received 7 implants following extraction and bone leveling. OptiSplint was scanned extraorally as per the new protocol and the healing collars and screws intraorally. Doctor printed in house and his lab person created a model to verify printer accuracy on the first case. Superb outcome.
