If the only reason is to eliminate the possibility of powder causing sensitivity I think I'll wait and do once right before cementation.

Sensitivity with the powder has not been an issue.

One less step to worry about. Smile


i'm not sure if i follow you. where do you save a step by not bonding directly after you prep? you are going to have to bond anyway and you are going to have to get rid of the powder as well.
maybe i'm missing something. it is monday so i could be a little slow - have been many times before!!!!

Either is fine, but know that options are available.

I think its me that's confused, I understood that you are bonding right after the prep with Sim1 and Sim2 and then again right before cementation with the Interface and the Sim2

If you don't bond again right before cementation what's your protocol to clean off the tooth after the pt. has been waiting around for 20 min.?

after the pt has sat for about 12 minutes for a crown to mill i usually put a fresh coat of sim 2 on the prep after i have scrubbed the prep with alcohol and washed that off. accordinly to JK it is not necessary, but i do it just because i have OCD!!!!

take care,
d

"12 minutes for a crown to mill "


are you using the fast mill option routinely?

the only time i don't use fast mill is in an anterior situation where the margins are routinely thin. otherwise i'm with CK; almost exclusively.
take care,

Agree 100%-- if I have a less-than ideal shoulder, I am milling in slow-mode. Otherwise, everything else gets full-speed/fast milling.

I got to get with the program and try the fast milling function.

Have you noticed any difference in appearance/fit in fast over slow Question

aurelio,
the only difference i have seem is with SEM's. they do show a rougher appearence and slightly more microscopic fractures/chips at the margin. i would almost expect this since each pass of the bur is 25 microns thicker, but i see nothing clinically.
the SEM's were taken by Lee Culp to see what was going on at the marginal area with fast milling.
take care,
d

just did my first fast mill crown, on #12. 10 min. 45 secs. not bad! and the fit and margins are as good as the regular mill.

i'm glad i'm talking to you guys, thanks Smile

Have done a few this week--

the only thing is that it makes the powder harder to get off the tooth. Any thoughts on a good solvent that won't mess up my hybridized/sealed prep?

Thanks.


This is an old thread, but I wanted to know if there was any new ideas in cleaning off the powder stuck to the Simplicity hybridized layer. Is the air inhibited layer what causes the powder to stick? If so can alcohol be used prior to powdering to remove the air inhibited layer without affecting the hybridization?

That powder is really heavy and it sticks to anything moist.

I found that it is best removed with alcohol and then a water rinse- sometimes it takes a couple of rounds.

Following rinsing and drying Sim 2 can be re-applied to freshen the surface.
