I was in the same boat. Had been letting Glidewell do our temps. But, with 3Shape's new Temp solution, its became practical to make our own. In the end, i don't believe its the best (most lucrative) use of mill time, so I made the decision to not go after the bottom of the market. I went with a fee that works out to about 40% of my PFM fee. Basically I get the cases I wanted - those for which I would like to be "in the loop" during the planning and temporization phases of treatment. I make a little money on the temps, but more importantly, I'm not having to deal with someone else's idea of proper tooth arrangement and contour...
