"It is a mandibular advancement splint that was way too expensive for pratitioners. So to get around that they used a ema mandibular advancement splint design (buccal elastic straps) and printed it to save money. Nothing new there."

We know all that, anyone who has researched OVN, whats your point Quakka?. My understanding is OVN's device has the highest efficacy next to the gold standard cpap masks. Resmed and others are doing very well despite the 50% plus of users who discontinue in the first year. USA Govt Health part funds them and with the consumables and replacement every three years OVN's revenue will be great as long as they continue signing up sleep centres etc.

Can you back up your last paragraph, sounds interesting , if you have the evidence, thanks.D
