Researchers Develop World-First Intra-Oral Device For Weight
Researchers have developed a world-first weight-loss device called DentalSlim Diet Control to help fight the global obesity epidemic. This is a safe noninvasive and reversible device that is cost-effective also. DentalSlim Diet Control is an intra-oral device fitted by a dental professional to the upper and lower back teeth.

It uses magnetic devices with unique custom-manufactured locking bolts. It allows the wearer to open their mouths only about 2mm, restricting them to a liquid diet, but it allows free speech and doesn't restrict breathing. Participants in a Dunedin-based trial lost an average of 6.36kg in two weeks and were motivated to continue with their weight loss journey.

Lead researcher, Professor Paul Brunton says the device will be an effective, safe, and affordable tool for people battling obesity. It is fitted by a dentist, can be released by the user in the case of an emergency and can be repeatedly fitted and removed. The main barrier for people for successful weight loss is compliance and this helps them establish new habits, allowing them to comply with a low-calorie diet for a period of time. It really kick-starts the process," Professor Brunton says.

"It is a non-invasive, reversible, economical and attractive alternative to surgical procedures. The tool could be particularly helpful for those having to lose weight before they can undergo surgery, and for diabetes patients for whom weight loss could initiate remission. The beauty of it is that once patients are fitted with the device, after two or three weeks they can have the magnets disengaged. They could then have a period with a less restricted diet and then go back into treatment.

This would allow for a phased approach to weight loss supported by advice from a dietician allowing long term weight loss goals to be realised. Patients are given a tool to open the device in an emergency, but none of the study participants needed to use it. While they all described the device as tolerable, the design has since been improved, making it smaller to improve functional comfort and aesthetics.

"Overall, people felt better about themselves, they had more confidence and they were committed to their weight loss journey," Professor Brunton says.
