I breathe through my mouth since my nose is always stopped up.  I'm using a full face mask at this point, but it sounds like the oral appliance may be better to avoid leaks, sore spots on the bridge, etc.  Does the air go to both the mouth and the nose, or just to the nose?

I see that no one has answered your question.  I'm sorry that I don't have an answer either but have wondered about that myself.  Sometimes a stuffy nose makes me miserable enough to just stick the hose in my mouth. Hahahahah.. I don't, but it is definately tempting.  
I hope your issue has resolved. Take care

I just started using an oral appliance this past weekend. I can breathe through my mouth or my nose, which ever I prefer.

That's good news.  Does it block the mouth so pressure does not escape?

AlphaPrime...Hi just wanted to give you the information I have on the oral mask.  I ordered the Oracle452 a couple of weeks ago.  It goes in  your mouth and seals over your teeth.  There are nose plugs that you put up your nose to keep from breathing through your nose.  The instructions said that you may only have to use the nose plugs for a couple of weeks.  Since you normally mouth breathe this may not be an issue with you.  It makes your mouth (or at least mine) extremely dry.  Also had problems with mouth sores and pain in my jaws.  I have had surgery on both my upper and lower jaws, so this may be the reason for pain. So, far I have not successfully used it. Only a couple of hours at a time.  I haven't really given it a fair chance.  I have only been on cpap and now apap for about 5 months.  I am on mask number 4 and plan to get another one next month when my insurance will pay for a new one.  I hoping to get some input from cpap users who have a full face mask that works for them so I can make an educated discison when I choose my next mask.  Anyway for the good news, there are people on this site who love the Orcale452 and are having great results with it.  It's all about what you can tolerate.  I plan to give the Orcale a chance, just haven't done that yet.  Good luck and keep us posted on you progress.

It actually pulls the jaw forward, out of the airway to keep the airway clear. If this works (I have a sleep study scheduled), I'll no longer have to use cpap (this is to replace cpap).

I suffer from a nose that is blocked most of the time too. I have no problem sleeping with a dental appliance.

I am also a mouth breather (& snorer) With my appliance, I can even get a drink of water with it in! I have no problems with it at all.
