The robot is used to show how well potential new products or prototypes are performing when it comes to plaque removal.
Built using a scan of a real canine mouth and jaw, the 3D-printed model replicates the normal mastication action of a dog and the pressures it might exert on a dental chew. This, the company says, allows it to test the effectiveness of different product materials and shapes more rapidly and then refine its products at a much earlier stage in the research and development process.
Dr Phil McGenity, Global Pet Oral Care Technical Leader, Mars Petcare said the robot allows them to observe the effects of a dental chew much more easily than in a real dog: "Typically, it’s very difficult to look inside the mouth of a dog while it's chewing, but this robot allows us to assess products more rapidly than we’ve ever been able to in the past. It means we can continually improve the texture and materials in our products."
Mars uses the robot to compare different textures and shapes of products by analysing how much plaque is removed from the robot’s teeth.
Phil said: "We apply a plaque mimic to the surface of the teeth, so we can observe how effectively different prototypes or textures remove this mimic. We take before and after images and, using computer analysis, we can accurately determine what percentage of plaque has been removed.
"This robot has been extremely beneficial for us, to see just how visible the effects of our products, such as DentaStix Daily Oral Care, are."
Veterinary dentist John Robinson said: "One of the key benefits of the chewing robot is it allows a preliminary testing stage before you move into clinical trials. Clinical trials are lengthy and expensive, but the chewing robot means the product can be refined and improved to ensure optimum effectiveness.
"Then you can move into the full clinical trial knowing it has already had extensive texture and plaque removal analysis."
He added: "New research developments such as the chewing robot are vital to improving home dental care in dogs and giving vets the confidence to recommend dental chews to dog owners. Although brushing is regarded as the gold standard, vets need to work more closely with owners to improve homecare via the use of dental products."
