Distancing driving the parametric model

Inspiration

Competing in ju jitsu and hockey and underwater rugby, we've both had concussions. More than that, not nearly enough of our friends wear gum shields; they're uncomfortable, finicky and expensive. With more and more focus on concussions in sports (for example in the NFL) and lives too fun to spend in recovery, we wanted to change that.

What it does

Using a custom camera & light arm, our model interacts with you as you scan your teeth. A chatbot gives you real-time feedback to ensure your capturing the correct images, until it is satisfied with the quality of pictures. Measurements can then be taken from these images to inform a CAD model unique to your teeth, before this is then printed in TPU for a ready-to-go mouthguard! Back to cage-fighting and Gaelic football you go.

How we built it

We used the build a chat assistant using the Pixtral 12B model. We prompted it to be a helpful assistant, then gave it images and used them to analyse what parts of the mouth still needed to be captured. This was converted into a friendly voice prompt which we feed into a text to speech model. We then built a parametric CAD model for which we could then use the measurements to make a custom insert for the gum-shield, which we printed in TPU before putting into a PLA outer.
