Carestream's intraoral scanner ranks first in trueness, study finds


Carestream Dental's CS 3700 ranked first in an in-vitro study of intraoral scanner trueness.

A new comprehensive in-vitro study testing the trueness of 12 intraoral scanners when scanning full-arch implant impressions found that Carestream Dental’s CS 3700 intraoral scanner offered the truest results when capturing scan bodies in an edentulous arch.

The study compared the trueness—or how closely the digital scans matched the actual object—of 12 intraoral scanners when scanning a stone model of an edentulous arch with scan bodies. Two methods were used to assess trueness: Method 1 directly evaluated the quality/accuracy of the scan of each intraoral scanner, while Method 2 evaluated the resulting accuracy of each intraoral scanner in early stages of prothetic CAD modeling.

Carestream Dental’s newest scanner, the CS 3700, was shown to have the best trueness, with a mean error of 30.4 μm when tested by Method 1. The study found the performance differences between the scanners tested to be statistically significant, with the CS 3700 outperforming the other 11 scanners.

“Being able to confidently scan a full edentulous arch is every scanner manufacturer’s goal,” said  Ed Shellard, DMD, chief dental officer, Carestream Dental. “The CS 3700 features advanced acquisition software—CS ScanFlow—that ensures the accuracy of the dataset while making it 20 percent faster than the Carestream Dental CS 3600 intraoral scanner.”

Taking into consideration the results of both methods, the study ranked the CS 3700’s performance among the intraoral scanners with the highest accuracy, defined as having a mean error of <40 μm with Method 1 analysis and < 25 μm with Method 2 analysis. Carestream Dental’s CS 3600 intraoral scanner was also included in the study and was also listed among the scanners with the highest accuracy.

The study was conducted by BMC Oral Health. The full study can be found here.
