I started using an OA called the SUAD device about 3 months ago.  This device allows one to titrate the amount that the lower jaw is held forward using small 1/2 and 1 millimeter spacers.  Initially it worked very well for about a week.  The I  would wake up occasionally and feel like it hadn't worked at all.  So I gradually increased the spacers to about 3 mm beyond what the dentist's initial setting for me was.  But now it doesn't seem to be working.  My spouse says that I no longer snore, but I still wake up feeling like I experienced apnea.

Today I obtained more spacers from my dentist and I'm just wondering if by increasing the amount my lower jaw is forward more and more will make the apnea stop again.......or will my jaw just get used to this increase and I will start to have apnea again.

Anybody have any input on this?

tedh,
  You might ask about scheduling a titration study with your oral appliance, to determine what setting effectively treats your apnea.

thanks Okie.  when i first got the OA, the dentist had set it for me but said i would have to titrate it on my own according to how i felt each day when i got up.  But i'll ask him if a professional can do this study, or i'll call up the company itself and ask them.
