So I don't have a sandblaster but I know there will be times I want to bond metal. I work as an associate and I know they won't buy one for me, and if I buy one myself no doubt it'll get nicked. Anyway...

1) Prefab steel posts. At the moment I am giving them a few passes with a black-banded super coarse diamond bur without water spray, then rinsing with alcohol, Sur 2 and cure

2) Metallic crowns. Is it acceptable to have the lab sandblast the metal, do my tryin, then rinse with alcohol and place Sur 2?

3) Zirconia. I haven't touched these yet...

Some posts are already very rough. Nothing else is needed. I'd use a fine diamond instead of a coarse one.

2) Metallic crowns. Is it acceptable to have the lab sandblast the metal, do my tryin, then rinse with alcohol and place Sur 2?

Yes.

3) Zirconia. I haven't touched these yet...

Maybe have the lab sandblast them as well.

This is probably more suitable for the anchor forum but I don't want to keep spamming your message board, and since we're on the topic of posts anyway...

I've been placing my bonded steel post into a sea of anchor, then making the composite buildup from there - I do not light activate any of it until the whole thing gels. My rationale being that the post space has a ridiculously high C factor - is this acceptable? If it makes any difference I'm usually using the white opaque.

And yet in an endo'd molar chamber, I will place my first increment of anchor usually 2mm thick into the chamber and light activate that before placing the rest - this increment would also have a pretty high C factor - is this of any clinical consequence?

I am a huge fan of the danville micro etch-- it's in my lab and is used all day long--
You will kick yourself for not having one sooner.

Those are reasonable things to do.

Alan

Could you not buy one and take it home with you each day? They're not that expensive and they attach via quick disconnects.

JK,

I'm in the market for one as well? What are some good brands out there?

Thanks

The Danville micro etch is awesome.

Clinician's Choice used to have something to contain the particles and it fit on the end of the suction tip.

The wet/sandblaster is really a messy thing.

Danville microetcher gives 1 for free with the kit. Does help with the mess but I don't get to see where I am shooting.

Care to explain why the wet sandblaster is messy? Doesn't seem messy in youtube videos.

Thousands of particles per second flying at 3 barr bounce off hard surfaces!
