Reverse Preparation & Two-Cord Impression Techniques

Is anyone out there using this technique? It seems like a great idea, however we are discouraged from using burs that are not issued by the school because we rent our equipment.

I would like to know what you guys are using and what you guys think about this concept.

I haven't had time to watch the video, and I don't know what a reverse preparation is. But I use a two-cord impression technique, as do many of my colleagues. I think it's one of the best techniques for getting retraction and minimizing bleeding, but it requires excellent placement of the cords. If done according to instructions, you'll get excellent impressions.

We are encouraged to use reverse technique but not required here at Case. I've used it on all my anterior C&B and veneers to minimize trauma to the gum tissues. Kind of overkill, I've used triple cord impression technique since third year and never had any problem with all my crowns and bridges during final deliveries.

For any of you who saw the video, did you happen to see the rapid anesthesia vid? Are any of you guys using this?

I've never had much luck with Expasyl. I like to go subgingival with my preps, and Expasyl doesn't seem to do much with that. If you're supragingival, well you don't really need cord.

I generally go 1/2mm-1mm subging as well. it works wonderfully. When you pack cord you are often tearing tissue. Its almost impossible not to. Maybe you are using expasyl incorrectly. Its obvious cord nor expasyl is not needed for a supraging prep.

Reverse prep is quite interesting. My feelings though are that you will always over-reduce your prep, just to avoid any undercuts. Still interesting though, just not for everyone ...

I'd much rather over reduce a tooth than under-prep it! And 99.9% of lab techs out there will agree with that statement.

Seriously though I haven't packed cord in about 5 years. I do my best to keep my finish lines at or lightly above the gingival margin to the point where expa-syl is wonderfull and if the tooth dictates I need to drop sub ginigival to get a finish line then I'm using my soft tissue laser to clean things up.

We've had some good luck with Expasyl where I work... always seems to stop the bleeding and leaves everything pretty clean. Not cheap though, and the little carpules dont expel 100% of their contents so there seems to be a lot of waste for such an expensive a product. Although I guess if it works, money is a non-issue.

Have you tried soaking the carpules of expa-syl in some warm/hot water for about 5 minutes before using it?? Makes it much more "flowable" without doing anything to its great hemostatic and retraction properties!👍

I used Expasyl for the first time today on a #8/9 crown case. The finish lines were just barely subgingival, and it worked great on the first try. I like your idea of soaking them in some hot water, too; I'll try that next time if I remember.
