Resin material...Preference?

Greetings all,

I'm currently using Kerr's Revolution Formula 2 for Class 3,4,5 restorations and 3M Filek P60 for Class 1 and 2 restoration. The first one is a flowable composites. So far, I've had great success with material.

I'm just wonder what material are you using in D-school or private practice? And why?

I just want to see if there is something else better on the market that I am not aware of yet.

Also what is the main difference between the flowable and capsule type of composite? (other than the handling properties).

Thanks

You're using flowable for Class II??? I believe the main difference between flowable and packable is the percentage of filler material... Composites are glass beads suspended in a resin matrix. The less filler, the more flowable. The smaller the particles, the more polishable, but also the less wear resistant. So, using a flowable in a Class II is not a good idea, since you're giving up wear resistance. Personally, I use Premise by Kerr. It's soft enough to be sculpted, and polishes very well. I can't comment on wear strength though... I have no idea to be honest. UNLV uses it, so they must have a good reason!

We are not taught this in school, but one of the best techniques that I have seen thus far uses flowable between increments. It takes a little more time, but eliminates submargination at the cavosurface. Kinda takes the guessing out of it I guess.

I know a good number of dentists who use flowable before the first layer and/or between increments. Personally, I don't like it. I wish I had literature to back up my statements, but I'm too lazy to look it up. So I'll try to reason it through. Packable has a higher wear resistance, and likely, a higher modulus of elasticity. Flowable would be less on both counts. So if you've got enamel, dentin, packable, and flowable, you've got 4 different materials with different moduluses and different temperature expansions. The "filling" is not a solid piece, but rather an amalgamation of two materials. Thus the filling will not expand in one piece, but want to break up into component parts.

That may be a bunch of B.S. One of these days I'll ask someone smart. Until then, that's the story I'm sticking to. I use Premise which flows very well even though it is a condensable composite. If I had to use Herculite, which is a packable composite, I probably would be using flowable as the first layer.

I made the correction to my post. Only Revo 2 is a flowable.
Brainfart. Thanks for catching that.

I have to admit that seems to make sense.

I've done the flowable first, I've done the no flowable also. Personally I don't notice any difference in how the restorations look, wear, hold up, and most importantly patient post tx sensitivity!

Composite wise, I'm a Kerr fan too. In general I use their Premise composite for my anteriors (I love the way it polishes and handles in situations where I'm doing fine shaping/sculpting with either a brush or composite instrument pre-curing). I usually use Kerr's Point 4 for posteriors (I can't really explain why I use it over the premise in the posteriors except that in my hands atleast I just like the handling characteristics of the Point 4 over the Premise). If I'm going to use a flowable, I use Kerr's Revolution.

In general, my technique is: prep, apply a thin layer of Fuji Liner to any exposed dentin, etch, bonding agent (I'm partial to Jeneric-Pentrons Bond 1), composite in layers, done.

One thing that you'll find in private practice is that after a few years, you'll tend to accumulate a few brands of composite and bonding agents. You'll see an add in a dental journal/read about it online in a dental forum or see it at a dental meeting the "latest and greatest" from a manufacturer, and you'll buy one of their introductory kits, try the material on a few cases, and then realize more times than not that you still prefer your "old faithfull" material over the new stuff. You'll then tell your assistant to put the new stuff in the storage closet (or wherever your keep things you don't use very much) where it will start to collect dust. The one day 5 years later you'll come across that "special case" where you want that material and your assistant will look at you like you have 5 heads when you ask for it and then go hunting for it all the while wondering where the heck you came up with the idea to use it!🙄 Don't laugh too much, this statement will apply to just about any student here in a few years!😀

It usually turns out that:

A) Someone misplaced it so you can't find it, or
B) It expired
