GrammetryTM
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:
- Implant location accuracy
- Predictable outcome
- No need for retries
- Reduced chair time
- Elimination of tryins
- Ease of interaction with your dental lab partner
Grammetry vs Photogrammetry
Grammetry enables clinicians to experience all of the listed benefits of photogrammetry, and none of the unique challenges that photogrammetry presents.
Concerns | Photogrammetry Challenges | Grammetry Solutions |
---|---|---|
Applicability | Limited application | Multiple applications |
Learning Curve | Steep learning curve | 15 min learning curve |
Mobility | Limited mobility | Easy mobility |
Scalability | Expensive scability | Inexpensive scalability |
Upkeep | Continuous upkeep | No upkeep |
Availability | On backorder | Available now |
Cost | Expensive | 1% the cost of photogrammetry |
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.

Grammetry – Meeting you where you are
The dental community represents a wide spectrum of digital evolution and technology adoption. The purchase of a high-specific, single-utility, expensive tool is outside the reach of most. ROE has designed Grammetry to meet you where you are from a technology perspective.

Uses of the OptiSplint
The OptiSplint is appropriate for both day-of-surgery and the restorative process.
Grammetry Kit
Grammetry Kit comes in a 4, 5, or 6 scan body pack. It includes:
- OptiSplint scan bodies
- Screws
- Prosthetic scan caps
- 2 metal frames (one large and one small)
- 2 frame delivery handles
- 1 pair of frame clippers
Additional items available for this system are the ArchTracers (fiduciary markers, pack of 3). These are one-time-use items that can be autoclaved post-surgery.
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.
