 Well, that's a great question. You know, a lot of dentists, you know, they just don't know where to put regular dental implants, you know, and they haven't, you know, taken their training and their experience to the next level. And so they don't really know that that kind of treatment is out there. And if they are aware of it, they don't see it on a regular basis. So they don't know if they should be recommending it to other people.
