One of the most common mistakes when using an intraoral scanner is not following a clear scanning protocol.
When the operator moves in an unstructured way, constantly changes direction, or skips areas, the software has difficulty aligning the images correctly. This can lead to distortions in the digital model, especially in longer scans.
Intraoral scanners build the model by stitching together multiple captures that must follow a logical sequence. When this sequence is broken, the system loses reference points and accuracy decreases.
Another frequent mistake is scanning too fast.
The system needs time to capture and process the data. If the movement is too fast, references are lost and incomplete or distorted areas may appear.
How to avoid it
Follow the same scanning pattern every time
Maintain a continuous movement
Avoid abrupt direction changes
Keep a steady speed
Conclusion
A clear protocol and controlled speed are essential for accurate scans.
