Poly sulphide is obsolete now...u can use Zoe..for tertiary and secondary impressions..Sent from my iPhoneOn 5 Apr 2012, at 12:54, "mpt765676" <mahmudp@...> wrote:

Thank you Divya!

I did think we should use PVS( addition silicone)...but i read in someones post previously to use condensation and so I got really confused.

Ive gathered a few points from the Pink book...can you please clarify if they're correct?

1. Addition Cured: for crowns...

2. Polysulfide: for Complete denture

3. polyether: for bridge work and implants. used where increased # of preps..

It also says to use ZOE paste to record edentulous ridge or patients existing dentures.

So what to use for CD?

REALLYYYYY appreciate the help!
