The MouthPad, a clever wordplay on the word 'mousepad', is a retainer-style contraption equipped with a touchpad, battery, and Bluetooth connectivity. Developed by Augmental Technologies Inc, a spin-off from MIT Media Lab, the device is crafted from KeySplint Soft resin, a dental-grade material commonly used in aligners, bite guards, and similar oral appliances. The battery is produced by a company called Varta, renowned for its history of producing safe, medical implant-grade batteries, according to the creators of MouthPad.The mouthpiece closely resembles an Invisalign retainer, though it lacks the section covering the front teeth and incorporates computer components. Similar to a conventional retainer, individuals must provide dental impressions during the ordering process. Subsequently, the retainer is 3D-printed based on the individual's dental structure.
