I recently got fitted for an upper night time mouth splint and a lower daytime splint. After using both for roughly a month, I went in and they put a "pivot" on my upper night time splint. This was no more than a hard ball that is placed on the splint where my bottom left molar would hit it. This is the only point of contact when I close my mouth and supposedly "75% of patients see an improvement after 2-3 days" from this. After 3 weeks, this "pivot" is then removed. Has anyone ever heard of anything like this?
Certainly sound like the pivot appliances of old.... largely discredited now as of little chances of long term success. I would think they were trying to "recapture" your disk. Studies show that in the long term, they do NOT stay recaptured.
