Its defined as "Implanted Corneal Lens"
:a plastic lens cemented into a section of decalcified tooth that is then stitched into an opening cut in a totally opaque cornea to restore vision. The lens may be implanted after normal corneal grafting has failed.

This is actually a very new procedure, medically speaking, and there have been modifications altered to increase periphery visions. ‘te this is rather ‘new and uncharted territory, so to say.
What they try to do is determine whether key properties of extracelluar matrix macromolecules can be replicated within tissue-engineered biosynthetic matrices to influence celluar properties and behavior. This does work because the hydrated collagen and N-isopropylacrylamide copolymer-based ECM are fabricated; the structural and immunological simplicity of the cornea and the importance of the extensive innervention allows this symbiosis to occur. The teeth has such capabilities. What happens is that they graft the laminin adhesion pentapeptide motif, YIGSR and this actually promotes epithelial stratification and neurite in-growth. It actually regenerates the corneal epithelium, stroma, and the nerves. In particular, functional nerves will regenerate in implants. As we know there are mulitple nerves within the facio-skeletal structure. Hypothetically speaking 'te, they can even use this to stimulate neuritic-in growth in other nervous regions. The problem is making it small enough to allow regrowth of small nerves in the cranial super structure or the regrowth in broken spinal column without harming the spinal nerves (which if done could kill the person). But hypothetically they can even harness this and allow nervitic re-growth of spinal nerves.
Technology will have to develop to allow the procedure to introduce such laminin micromolecularly.
And to do this, science and researchers need to test this on animal models before they can even proceed with human models. Then it will take more years to pass a medical board, a review board, etc etc.
Its possible. The problem is the method in completing it. Technology is still a lingering problem.

Its weird, how such a simple tooth can allow this. But its explained biochemically.
‘te, the way God designed us is IMPECCABLE.
That’s all I can say.
