Mandibular Advancement Devices - is your mouth supposed to be closed ?
#21
RE: Mandibular Advancement Devices - is your mouth supposed to be closed ?
I've been using a MAD device successfully for over 7 years.  The device was slowly adjusted to give effective treatment at first.  I adjust it based on how my symptoms are being mitigated.  The device hasn't made my jaw joint sore that i remember but i have had a few times when my teeth are slightly sore after a large increase in treatment.  My mouth stays mostly closed but i do have times of excessive saliva production.

my history::  A sleep study indicated my AHI was 10 or higher and my O2 charting showed marked declines which sync'd with the times i knew i was waking up.  I did try CPAP early on but couldn't tolerate it.  I use a TAP3 custom fit device I got from my dentist.  We tried a less expensive, lighter built, option but my clenching habit cracked the device after a couple weeks.

The MAD works for me due to the nature of the apnea.  I knew from paying attention when i was rousting up at night that my jaw and tongue were sliding back and causing obstruction and lots of snoring.  My sleep habit complicates the situation as I hook a finger over my chin and pull it down which ensures obstruction.  Whenever my MAD is in the shop (a few days every few years so far) i can tell a big difference in how i feel those days.  I've tracked my O2 levels with and without the device and the difference is marked.



PS:  The CPAP listed in my profile is what my wife uses which is why i'm here.. but maybe my MAD experience is helpful.

Sorry about the really delayed reply...

I've checked my O2 a few times over the years with a logging PulseOx.  We had a finger type but have a SleepOn ring type now.

Was still worth it for the improvement in apnea but it's something to be aware of. My bite did go back to normal when I stopped using it though.

That happened to me too.

I started off with a mandibular device and moved to CPAP when my front teeth no longer touched and I could not bite.
My teeth returned to normal by themselves.

Re the OP’s question, I always mouth-breathed with the splint, but only nose-breath with a CPAP machine.
