[Dr David Cunnington]: So, amongst dental appliances, Harry, there are some that are adjustable and some that aren't adjustable, and some fitted by dentists and not fitted by dentist, so what's the difference between them?
[Dr Harry Ball]: Yes, so there's a really big market for the what we call boil-and-bite, so it's a one-size-fit-all-type device which you can buy on the internet or in various stores. And the way they work, and I'll show you one of them. So, this is one from a large retailer. I won't mention their name, but they sell whitegoods and furniture, but they've now gone into the sleep apnoea area. To the Australian Sleep Association are quite concerned about a retailer treating sleep apnoea and the main problem is that they're selling a boil-and-bite one-size-fit-all appliance like this.
[Dr David Cunnington]: What do you mean by boil-and-bite?
[Dr Harry Ball]: Boil-and-bite. Yes, so what it means is that because you only get one go to get it right and everyone's jaw's different, they've got to make it pretty big to fit round everyone's jaw. So, it comes in a template like this or a framework like that and you put it in boiling water to soften it, then you fashion it over your teeth, and you've got to work out the right forward position of the jaw as well and this is how these work. This is one of the more sophisticated ones in that you can bring your jaw forward here, but a lot of the ones that we find our patients come in with have bought them on the internet and you can't adjust them at all. And so they're only thirty/forty dollars or so. They get a moneyback guarantee. Often, they claim that there's clinical trials and that kind of thing. But really, almost invariably people can't use them, because the main problem with this type of appliance is that they don't fit well so you've got poorer tension. It's really important that these appliances stay firmly on the teeth, so they kind of drop down. But the mouth's a sensitive place and they tend to be quite bulky as well and they put more pressure on teeth, so they're some of the problems.
