Hi John,

I have been using Simplicity for along time with good success. Recently, I have noticed some restorations where the margins seem to be breaking down and getting stained early on. I am concerned about this. Do you think it is possible I am not curing well enough?...or, do you think the problem may be my light. I know I haven't been pulse curing like I should, mainly because my assistant does not understand the correct process. Could you critique what I am doing so far and make suggestions so my assistant and I are on the same page?

1. Cure simplicity 10 sec.
2. Flowable 20 sec.
3. Each composite layer 10 sec.
4. Adjust & polish, then cure 10 sec. per surface.
5. Done

Thanks, Jeff

First, agitation of Sim 1 for ten seconds on cut enamel and 20 on uncut enamel. Make sure that's being done.

But I have a suspicion it's a solvent thing.

All things with acetone must be used immediately after dispensing.

Make sure the color of Sim 2 is PALE YELLOW. If it is at all darker acetone must be added to bring the color back to pale yellow.

Be certain to dispense the Sim 2 only when you're ready to use it and then use it immediately.

Have you checked your light recently?

Also- be sure to check the pulse activation protocol on this site.

The lights are brand new. I am not even sure of the name of the lights. They came with my Design Ergonomics delivery system. I used to use the UL5.

I don't have a light meter, currently. Design Ergonomics is sending me the specs on the light as we speak. Do you think I should return the lights and go back to the UL5?

hard to beat a UL5, but you can probably use what you have. You need to get a meter though.

Do you think I should switch from Simplicity to Surpass, Eric? I mentioned this to my staff and they weren't too excited about the extra step and bottle to deal with. Do you find it takes much longer than Simplicity?
For the most part, Sim has worked well for me, so why change?

I did. Works for me. The extra step isn't really an extra step, as you have to apply the Sim2 twice anyway, and it takes the same amount of time.

The thing I really like about Surpass vs Simplicity, is that it's applied the same, no matter what you're doing. No different protocols if you're doing a CBU vs filling vs bonding a ceramic crown.

Better bond strenghts are a bonus too.

Oh, and as for what your staff has to say about it.....


Who really gives a **** what they think about it????

I don't make decisions about what materials I use based on what my staff think about them. I really don't care.

Jeff, Eric is right.

That guy is right a lot.

OK, I've had some champagne, but still......
