So I used to go directly to Denmat but they're a bit expensive and now they've opened it up to anyone who uses Zirlux. I haven't tried it from this company but I've been in touch with them and they make it and they're pretty affordable: www.custom-milling.com
My understanding is if you call it Snap-on-smile, you might be running close to copyright or TM infringement and DenMat might come after you. So you might want to be careful using that - they probably paid alot in advertising, and DDS offices have to pay a premium to be a provider. This might have changed, but just be careful. A little R at the end of something tells me to be careful when quoting a name or someone. LCM
Where I used to work we got in on the DenMat brand SnapOn and had to pay an entry fee and sign, effectively, a non-compete that we wouldn't sell anything similar. But that was a while ago.
