Recent studies confirm accuracy of Dentsply Sirona's Primescan

Several national and international studies have compared the precision and trueness of the Primescan to other intraoral scanners on the market.

Several national and international studies have found that Dentsply Sirona’s Primescan intraoral scanner offers highly accurate digital impressions of the entire jaw, according to a statement from the company.

One of these studies was conducted by researchers at the College of Dental Medicine at the Medical University of South Carolina and was later published in the Journal of Esthetic Restorative Dentistry (Volume 32, Issue 2). This study is said to have demonstrated the Primescan’s versatility since the scanner not only records natural and prepared tooth surfaces with precision but also captures materials across all substrates and for complete arch scanning. The study looked at the effect of different substrates on the trueness and precision of 8 different intraoral scanners. The Primescan ranked first in 11 of the 15 categories and ranked in the top 3 in the other categories.

The University of Giessen in Hesse, Germany completed an in-vitro study on the accuracy of digital and conventional full-arch impressions in patients. The results indicated that among the tested scanners, only Primescan showed no significant deviations to long-span accuracies obtained with conventional impressions.


An additional study at Bejing University tested the Primescan and 2 other intraoral scanners in edentulous jaws. In precision, the Primescan reportedly performed significantly better than the other scanners for maxilla. When scanning the maxilla and mandible, there was no significant difference in trueness between the scanners.

“The studies confirm again that, with Primescan, we have provided our customers with a high-quality technology that delivers truly impressive results," said Dr. Alexander Völcker, group vice president CAD/CAM at Dentsply Sirona. "We continue to add and improve workflows with Primescan as we’re convinced Primescan’s outstanding technology opens the doors for more applications in digital dentistry. Thanks to the technology of high-frequency contrast analysis, Primescan enables our customers to achieve outstanding accuracy in digital impression. And the extensive positive feedback from our respected experts and users all over the world, our most important compass, encourages us to continue to lead in this area’s development and innovation.”

An in-vitro study conducted by the University of Zurich showed that Primescan’s preparation margin accuracy was significantly better in local accuracy for single-tooth preparations compared to the other scanner systems involved in the study.
