Primescan perfects digital impressions With its completely new, patent pending digital impressioning technology Primescan— the new intraoral scanner from Dentsply Sirona—enables high-precision digital impressions to be taken of the entire jaw. “Dentists rightly expect products and solutions from Dentsply Sirona, that make their work at the dental practice easier, safer and better,” says Dr. Alexander Völcker, Group Vice President, CAD/ CAM and Orthodontics at Dentsply Sirona. “Primescan offers the option of faster, precise impressioning which is easy to manage in the usual practice environment, is reliable, delivers clinically flawless results, and which is simply fun to use.”

Primescan’s optical impression system has been decisively developed. The scan of the surfaces of the teeth is done with high-resolution sensors and shortwave light, capturing up to one million 3-D data points per second. With optical high-frequency contrast analysis, they can now be calculated more accurately than ever before. Dentsply Sirona has submitted a patent application for this process. With Primescan, it also is possible to scan deeper areas (up to 20 mm). This enables digital impressions even for subgingival or particularly deep preparations. Virtually all the tooth surfaces are captured, even when scanning

from very shallow angles. Primescan captures the dental surfaces immediately, in the required resolution and with a high sharpness even at great depths,

thereby ensuring a more detailed 3-D model. Find out more online at https://lp.dentsplysirona. com/en-au/primescan.html

Gum disease bug may kickstart Alzheimer’s New research has uncovered how the bacterium commonly associated with chronic gum disease, appears to drive Alzheimer’s disease (AD) pathology. A paper recently published in Science Advances details how a team of international scientists identified Porphyromonas gingivalis (Pg) in the brains of patients with AD. According to researcher Jan Potempa, from the University of Louisville, Kentucky, USA, although infectious agents have been implicated in the development

and progression of Alzheimer’s disease, the evidence of causation hasn’t been convincing. However, “we now have strong evidence connecting P. gingivalis and Alzheimer’s pathogenesis,” he said. “An even more notable aspect of this study is demonstration of the potential for a class of molecule therapies targeting major virulence factors to change the trajectory of AD, which seems to be epidemiologically and clinically associated with periodontitis,” Potempa added.

In its Federal Budget submission, the Australian Dental Health Foundation has called for an increase in government funding for oral health programs for some of Australia’s most vulnerable people. With the ADHF already delivering over $1.1m of pro bono care each year to disadvantaged Australians, ADHF chairman David Owen said the submission outlines how the Federal Government can, with funding assistance of just $226,000 over three years, help deliver over $5m of essential dental treatment to disadvantaged Australians. “Whilst the significant dollar value of services delivered by our volunteers speak for themselves, there are many stories that illustrate how the ADHF is making a difference to people’s lives across Australia,” Owen said. “With funding from the Federal Government, we will be able to increase the reach of our programs and make a difference to the lives of even more Australians by providing essential dental care that they would not otherwise be able to access.”
