Actually, @jg123456, this is nothing new. Dentists have been administering dental splints (designed for OSA) for years. Dentists are perfectly positioned to do so, as it is a device that needs to be adapted to ones teeth (like dentures).
This is a marriage made in heaven. You can quote me on that.
As to your issue with "training costs", I would go further and say that this is an example of the advantages of a large dental business versus small practices. If I want to distribute a product like this, who looks more attractive to me?: (a) a whole bunch of small practices with varying procedures/customs/standards etc, or (b) large corporate with standardised processes etc? Who is more likely to have quality controlled to the standards that I want?
And who is going to require less leg-work on my part?
I think this is just one of many examples, that shall become apparent with the passing years, of the advantages of a corporate's versus small practices. The fact that to this point, most corporate's have had a roll-them-up and get-rich-quick agenda, has meant that many have come to believe that it is a physical law, up there with F=ma, that dentistry is somehow immune from the benefits of quality corporatisation.
