Intraoral Scanner - Difference Between Accuracy and Precision

Accuracy

Accuracy is the difference between the true measurement of what you are scanning and the results of what you scanned. The larger the difference, the less accurate.  A crown that fits perfectly would have resulted from an accurate scan.

Precision

Precision on the other hand would be how often you can achieve those accurate results or at least the same result. Another word to describe precision is repeatability. If you can consistently get the same measurement, then you’re scanning is precise. If you scan the same patient twice and get two different results, then you’re not precise.
