Some Nice Burs for Smoothing Preps
One challenge with prepping for CEREC is achieving smooth preparations. I like to refine with red strip diamonds, then I was following up with a high speed brownie point, an idea I got from Daniel Vasquez which works very well, but you burn up about one brownie per tooth, and those things are expensive.
Here is another bur that I prefer.
They are from dentsply/essix, and are meant for the removal of composite cement after finishing an ortho case. They are made of fiberglass and last a long time, in fact dozens of cases. To smooth dentin you need to run at about 40,000 rpm with copious irrigation, but these guys last and last. I prefer the pointed and the football shapes, and use them for quite a few applications. The football really smooths out the occlusal aspect and axial walls.
I hope this helps someone.
That looks like a great product for running over the bonded margins.
As for the preps, I use a stripper bur and leave the axial rough, smooth the occusal & shoulder with an end cutter and have never had a debond or fracture after placement.
