How does the Scanguide solve the common problems with fiducial markers and full-arch scanning?
Traditional photogrammetry and intraoral full-arch capture present several well-known obstacles. The Scanguide was engineered specifically to address them.
The problems with conventional fiducial markers and scanning:
| Common Problem | Why It Causes Trouble |
|---|---|
| Inconsistent fiducial markers | Markers vary in shape, size, material, and manufacturer, and are rarely placed in consistent positions |
| Random placement | Markers land in the palate, ramus, or labial vestibule with no standardized location |
| Marker movement | Poorly anchored markers or mobile teeth can shift or fall out, losing the reference |
| Bloody, moving field | Blood, sutures, and flapping tissue make it hard for scanners to capture clean data |
| Repeating shapes | Identical scan bodies, suture caps, and healing collars confuse the scanner during stitching |
How the Scanguide resolves these issues:
The Scanguide provides a pre-created, fully integrated fiducial rather than relying on practitioner-placed markers and discretion. Its design delivers non-repeating geometries that let the scanner flow smoothly across the arch, and it masks the irregular surgical surface so the scanner captures stable, clean structures. Scan bodies, healing collars, or photogrammetry flags protrude through the Scanguide for capture.
Importantly, the system accommodates sedated patients without requiring cooperation or multiple bite registrations, and it removes the need for difficult ramus-to-contralateral-arch scanning patterns. The metal Fixation Base acts as "the constant," preserving spatial relationships throughout the entire surgical and digital workflow.
