It looks like they're offering an oral device that tries to fix the problem by moving the jaw forward. I was diagnosed with pretty severe sleep apnea about a dozen years ago. At first I resisted getting a CPAP machine and looked into some alternatives. A doctor recommended that I check with a local dentist that specializes in sleep apnea. His device cost on the order of $2500 (Insurance paid for most of it). It essentially just moved the jaw forward by degrees. After a couple of months of adjusting it he gave me the take-home test which showed that my apnea was actually worse with the device. Well, that was a waste of time & money. Got a CPAP machine soon after.
