Overjet's Dental Assist Receives FDA Clearance to Bring AI to the Dental Practice

 Over the last 5 or so years, I've had the good fortune to be able to evaluate more than a couple of dental AI systems for radiology.  It's been an interesting time doing that because reading x-rays requires nuance and, for lack of a better description, feel.  There is an "art" to looking at an image and being able to discern very subtle differences from one part to another and then basing your diagnosis on those nuances.  It is one of those things that is very difficult to explain.  There is no user's manual or IFU for understanding and interpreting radiographs.

That's why it's been so interesting to work with some of the problems.  AI can do amazing things, but it's one thing to discern a dog from a cat in a photograph to catching incipient lesions on a bitewing radiograph.  However, dental AI systems are evolving constantly and become better and better at what they do.

Now comes the announcement that Overjet Dental Assist™ has received FDA clearance.  The evolution of medical AI continues.  Here is the press release:

Overjet, the global leader in dental artificial intelligence, today announced that it received FDA 510(k) clearance for its Overjet Dental AssistTM product. This Software as a Medical Device product applies artificial intelligence in real-time to aid dentists and hygienists. The clearance by the FDA will enable Overjet to market and sell the AI product directly to dental practices. The software supports dental professionals in measuring mesial and distal bone levels in bitewing and periapical radiographs for the diagnosis and treatment planning of periodontal disease. The condition affects an estimated 46 percent of U.S. adults, including 8.9 percent who have severe periodontitis. Left untreated, periodontitis can lead to tooth loss and painful chewing.

"Overjet's Dental Assist clearance by the FDA is a landmark moment for dental AI," said Dr. Wardah Inam, PhD, CEO and co-founder of Overjet. "All clinicians can now have at their fingertips highly accurate software to detect and measure serious dental disease and clear AI visualizations to communicate with patients. This is big for dentistry and moving toward evidence-based, patient-centric care." 

In clinical performance testing, Overjet Dental AssistTM demonstrated automated measurement capabilities comparable to a team of highly skilled dentists. Overjet had three experienced dentists independently measure bone levels on dental radiographs using a measuring tool. These measurements were then further adjudicated by an oral radiologist to establish an official consensus ground truth. Overjet's AI-powered Dental Assist measurements were then compared against this dentist consensus and had an average difference of only 0.3mm.

"We're seeing dental AI software perform at the level of a team of trained dentists with accuracy closer than the width of a needle," said Dr. Chris Balaban, DMD, Clinical Director for Overjet. "These tools unlock the ability to track the progression of disease over time for each tooth and make the case for evidence-based treatment, supported by unbiased software and clear visuals for patients."

Three-year-old Overjet was founded by a team of PhDs and dentists from MIT and Harvard. They built the company around the mission of improving oral healthcare for all. To date, the company has raised over $10.5 million in venture funding and built artificial intelligence models to detect a variety of dental conditions such as cavities, gum disease, tartar and impacted teeth. Overjet's software is already in daily use by multiple large dental insurance companies to automate and improve the accuracy of dental claims review. The company has numerous partnerships with research institutions, dental support organizations and large dental practices.
