OSA is solved. I had a home sleep study, sent it back off and had an APAP machine delivered all within 10 days. Mouthpieces and alternatives are halfway houses on the way to a solution, not solutions themselves.

I guess it depends on your definition of solved, but by most standards it is not close.
