Iām curious about this as well. After I had a tooth removed, I had them restore the root with that ground up bone stuff so that it healed into a solid foundation that can support any gadget I may later wish to install. Iāve fantasized about teeth that can somehow triangulate a tongue implant and relay it to a muzzle to serve as an HID, a pointing device. I dunno.
Iāve been meaning to ask @Amal if anything every came of that magnetic post and the idea of trying to attach something to it thatās vibrated by a coil for magnetic sensation? [Tragus Implants and You (but also me) - #28 by amal] Maybe a little magnet in a drum/piston, like a maraca/cymbals, bolted into the jawbone to make an accessible osteointegrated implant for bone conductive hearing.
Even just that post itself, if itās reliable, standard, interoperable threading, makes for an appealing modular slot for swapable techno-teeth.
