I am going into lab today to work on my preps, I will look for the bur number.

The company IUSD buys from is Kimberly Clark and they nicely package and label everything in bur cases and ours so happens to be labeled: "Small chamfer, large chamfer [a fine and course diamond for each], interproximal, small shoulder, and large shoulder." This is our everyday bur block, but then we have about 9 million other bur blocks they give us.

Check back here around 1 pm whatever timezone Indy is in.

The company is actually Brasseler USA, not Kimberly Clark

it would have to be a 701, 702, or a #8 round bur. that is it.

Doc Smile,

I thought you were knocking on my post with your reply! Thnx for posting the pic, our kits at Temple don't have the "small chamfer" etc designations on them. As a matter of fact, for my PFMs, I start out with that "large chamfer" on a high speed for the facial, then make my shoulder your "large shoulder" on a slow speed.


Also, your shoulders have tapers while the one in my kit is a straight cylinder.

I am sarcastic at times, but it is usually obvious when I'm sarcastic 😛

I really like that our burs have tapers. At times I wish they didn't so I could better control my overall taper, but, especially on the distolingual line angle of the mandibular right teefers, the tapered bur helps me with making sure I am NOT undercut. You follow?

Since we just started doing ACC crowns, and my technique has greatly improved on the 15 or so teeth I have practiced on, I now like to use my 'small chamfer' on everything (occlusal reduction, axial reduction, interproximal, and getting the width of my finish line). Then, I switch over to a carbide finishing bur, I think Brasseler labels it s H851 or something - it is a straight cylinder with a flat-ish end. The end is 1mm thick which is perfect for the ACC finish line. It really smoothens up the prep, makes it shine, and allows me to get the second plane of occlusion without getting too much tooth structure taken off, and the rounded internal line angles where needed. However, this bur does leave a little lip of unsupported enamel so I go in with either a fine large shoulder, or an enamel hatchet, and take that lip of to give me what equates to a shoulder finish line. I have really come to dislike the shoulder burs because: 1) they are not end cutting, and, 2) if you done angle them parallel with your finish line, they take step-like divots out of your finish line - which happened to one little spot on my finish line from my project I just turned in...
