Full-arch scans are more prone to errors than partial scans.
As the scan progresses, small deviations accumulate, leading to distortions in the final model. This is related to the stitching process used by the software.
An unstable technique or interruptions increase this problem.
Operator experience also plays a key role.
Errors in technique, speed, or scanning strategy directly affect the outcome, even when using high-end scanners.
How to avoid it
Follow a continuous protocol
Avoid interruptions
Maintain stable reference points
Practice regularly
Become familiar with the system
Conclusion
Full-arch scans require greater control, and operator experience is essential for accuracy.
