From the VASRD, it appears that the only way to get the 50% is via CPAP/BIPAP, etc....I think the dental device would probably bring you down to the 30%, or 0% depending upon your symptoms. Additionally, if you do switch to the dental device, you should get another sleep study done asap using the device, because the PEB/VA will most certanly kick your package back and ask for another study because baseline study was done using CPAP. Also, if you are looking for a fit finding, switching to a dental device would probably help, where switching to BIPAP would probably hurt.
