I don't see where anyone has responded to your request. (Maybe I missed
it.)

I *think* you are asking about TM Disorders (TMD) and removable
splint-type devices which you refer to as "prothsesis" [sic].  However,
you could be asking for a website concerning disorders and pathology of
the actual TMJ (temporomandibular joint) and the FDA approved prostheses
which can can used to reconstruct the TMJ (artificial joint) in the USA.
But, I think it's possible that you are posting from another country.  
You might want to think a bit more about what you are hoping to find and
submit another post with more information.

I would also like to mention that you might want to subscribe to another
newsgroup with a focus on jaw disorders.
