 Posted: Wed Aug 29, 2012 10:19 am Post subject: Enhancing my surpass bond |
 |
|
Utter failure yesterday doing a build-up on a salvage job. Only wall still present was lingual cusp, decent enamel margin all around. Tooth has been exposed to oral fluids with MOD resoration and buccal cusp missing for I'm not sure how long. Tested vital to cold, would like to avoid endo if possible.
Good isolation, all caries removed (used Sable Seek), Surpass 1, 2, and 3 with Titan mixed, Anchor build-up. Let it gel, 40 seconds cure.
Prepping for crown, entire BU went right up the suction. Managed to still get a crude temp over what's there, but wondering how (or if) the bond could be enhanced best.
Did not use air abrasion yet.
Any other suggestions? Will probably lose it in time, but I didn't have anything better to do, and I like challenges.

What color was the Anchor? What's the expiration date?

White is tough because no light really gets through it well. You might a thin layer of Titan WO followed by Anchor A2. That will demarcate the buildup margin.

Material sets in 4 minutes, on its own, correct?
Should I wait longer to do my prep?

It usually does, but modulus takes more time to develop. If you need to stress it early, then try my suggestion. I know it will work.

I've done Titan WO thin layer, then rest Anchor for years now. BU's never fall out.

Is the reason you demarcate the BU margin with Titan WO, to make sure you bring the crown margin below the BU and has nothing to do with retention of the BU?
As regards retention of the BU, it would be Surpass then Titan WO and cure,
Seamfree and then Anchor. Now at this point would you let the Anchor gel on its own before light curing it? How long should you wait after placing the Anchor and curing before prepping the crown?
It would be good to feel more secure that BUs are not going to fall out either when the tooth is prepped or when the temp is taken off. |

no, you can barely tell the difference between the White Titan layer, and the White Anchor that makes up the rest of the build up. The thin layer of Titan is to make sure you have excellent adhesion and adaptation to the tooth.
I don't use Seamfree between the layers, but I'm sure it wouldn't hurt.
I let the Anchor gel for 5 minutes before the assistant lights it up. Gives me time to check Dentaltown... er a hygiene patient!
I start prepping the tooth right after the assistant has finished curing.

| So, is it important to use Titan WO in this method? I probably don't look at the shade of the Titan too often. It's probably A2. Why does the WO (white opaque?) work better holding the BU on the tooth? |

A2 would work fine too. Just make sure you drop your margin past it. I personally like white build ups. Easier to see.

This topic is perfect for me right now. I've had two buildups come off in the past week and it's concerning me. Nothing in my protocal has changed. One was surpass with WO then regular composite and the other was surpass with WO then anchor.
Seems the common between the two is maybe too much WO or not enough light activation of them? I generally place a little of the WO with the #3 then cure with the valo light for 10 seconds, then place another 1-1.5mm of the WO, light cure with valo for 10 second. After that either composite from a compule in layers or anchor. The anchor I let gel for about 2 minutes then light cure.
So please critique this protocal. Also I'm wondering with the WO should it be cured longer with the valo? My anchor recently for some reason seems to be taking longer to gel but maybe my imagination. I bonded an emax the other day and at 2:30 it wasn't really gelled yet but at 3 minutes it seemed really hard.
Please help.
Thanks.

WO takes a long time to properly and fully harden and light does not pass thorugh it easily since it is WO.
You might try applying some Titan and lightp-activating that first and then WO in thinner layers, light activating each one separately if you feel you need the white.
Another option is to place a layer of WO Titan over the Surpass and then regular A2 Anchor over that. That provides you with a white layer demarcating the tooth structure.

How long do you normally cure the WO for with a valo light on ten second mode?
You might try applying some Titan and lightp-activating that first and then WO in thinner layers, light activating each one separately if you feel you need the white.
I normally place a small amount of WO with the surpass 3 then LC together. Are you suggesting not using WO with the 3 but a conventional titan shade?

This is EXACTLY what I do and for the reason.
