VALIDATED CLINICAL SUPPORT
Yomi S for Pterygoid Implants
Yomi® S and YomiPlan™ are now FDA-cleared to support pterygoid implant placement — ready for use by clinicians experienced in placing pterygoid implants. No new hardware. No new software. Just more of what Yomi S was built to do.
The clinical opportunity with pterygoids
Pterygoid implants are placed deep in the posterior arch at 17-45 degree angles — among the most mechanically demanding positions in full arch dentistry. Yomi S was designed with the dexterity across the full range of anatomies with the required accuracy.
No Sinus Lift Required
Even with significant maxillary bone resorption, the pterygoid plate provides dense, reliable anchorage — bypassing sinus anatomy entirely.
Immediate Loading
High torque and ISQ values typically achieved in pterygoid bone allow same-day provisionalization, accelerating full arch restoration.
Superior AP Spread
The posterior exit point near the first molar delivers excellent anteroposterior spread without cantilevers or compromised stability.1
Why Yomi?
How Yomi S enhances this procedure
For clinicians experienced with placing pterygoid implants
Minimally invasive approach
Freehand pterygoid placement requires large flap exposure to visualize posterior landmarks. Yomi S may reduce the need for flaps — reducing surgical trauma and recovery.2
Navigation
During pterygoid surgery, Yomi S keeps you accurately on plan, even when anatomy is close to the drill path.
Accuracy holds at steep angles
Pterygoid implants are placed at 17–45° from the occlusal plane. Yomi S maintains its accuracy specification across this entire range.
Long implants, same accuracy
At 15-24 mm, pterygoid implants are longer than conventional — magnifying any angular error. Yomi S guidance is verified to maintain spec even at these lengths.

YomiPlan bone density mapping
YomiPlan’s bone density color overlay communicates the density of bone at the implant site in real time during planning — helping surgeons target the pterygoid plate at its densest region for maximum primary stability.
Clinically validated. Formally verified.
All Tests: PASSED3 • Zero Deviations
PASSED
Robotic Accuracy for Pterygoid Implants
Confirmed Yomi S guide arm and tracking system maintain accuracy requirements while drilling with Pterygoid-length drill bits.
PASSED
Total System Accuracy for Pterygoid Implants
End-to-end accuracy verified across the full workflow: CBCT imaging, scan registration, YomiPlan, and robotic execution.
PASSED
Human Factors Validation for Pterygoid Implants
Confirmed safe and effective when used by trained dental professionals with no additional robotic training required beyond updated user manual review.
Key conclusion
Yomi S robotic accuracy and total system accuracy are fully maintained for pterygoid implant procedures. No design changes to Yomi S hardware or software were required.
Yomi S: a platform with expanding capabilities
Pterygoid support is not a new product. The same Yomi S system our customers already use is now formally validated for one of the most clinically impactful procedures in full arch dentistry. As Neocis continuously invests in expanding what Yomi can do, your commitment to robotic surgery will keep growing in clinical and commercial value.
