full face mask problems

I have a patient that is using a Simplus FFM, his problem is in the tightening of the bottom straps, He is suffering from his jaw popping out of the socket due to tightening of the lower straps. I have tried a couple of FFM , the amara view, mirage Quattro, Quattro FX. All with the same problem. he has to tighten the bottom straps down. I tried the dreamwear mask with a chin strap but that did not work as pt was not able to get a full breath. He is on high pressures 20/9 cm. Does anyone know of a mask that might work, without having to tighten the bottom straps to the point where his jaws pop

The jaw problem should be diagnosed by a TMJ specialist. I had the problem a year ago and thought it was the Quattro FF mask that I had been using for 6 years. I went to a TMJ specialist and had special x-rays taken and was shown that my jaw bone on one side was wearing faster than the other. There are treatments for that. I elected to wait. Possible the problem is showing up because of improper fit of the mask....especially if he needs to tighten it so much.

You might want to look at the Oracle 2 mask. More information is posted in my signature block below.
