In order to effectively and accurately scan a full-arch case, Scan Gauges must be arranged to minimize IOS stitching errors.
By following these steps, it is highly likely that scan analysis will be successful.
Close Proximity
Scan Gauges are used in different lengths to "bridge" the gaps between implant/multi-unit abutment sites. For scans to be successful, the Gauges must be in close proximity to one another (<4mm).
Not Touching
Scan Gauges cannot touch one another, due to micron-specific measurements, any obstruction can mean an inaccurate scan.
Sufficient "Overlap"
Aim to have the sides of Scan Gauges overlap with the adjacent gauge.
Having the next gauge in the scanner field of view before moving to the next is necessary.
Ensure Gauge Is Fully-Seated
If the gauge is being obstructed by hard-tissue. Use a taller collar height Gauge.
Note: The greater the gap between gauge and underlying tissue, the harder it is to capture scans.
Use Retractors
To attain correct scanning data, there must not be any interference with the scanner. This means no lip, tongue or cheek. Utilize retractors for every scan to minimize interference.
No Rotation
Ensure that the Scan Gauge and the MUA are completely seated and torqued. Gauges cannot move between the Left to Right and Right to Left scans.
