Still love my rubber base. Just wondering what you are using?
Agreed accugel system is a good system..bought a full set of trays one set of each type...I will keep neocolloid in mind....I am going to try tropicalgin soon. I did a hydrogum 5 secondary alginate impression and they almost let me use it for finals...school protocol you know....have you ever used those asa edentulous trays with the border lock on outside of the flange? I have also purchased a nice polycarbonate try system from ASA which mimics the Massad trays except they are non adjustable...They are supposed to be good for either alginate or pvs. Will try on a few patients soon....I use virtual and I get good results. I tried aquasil and I liked it at first. I can't remember why I quit using it, but it is an addition reaction silicone, not a pvs. So it might have been that the adhesive stinks to much or something like that.
If you like Hydrogum 5, you might like the neocolloid stuff. It is also from Zermack, but it has better detail.
My all time favourite impression material is accugel. The system 2 takes fantastic impression for partials, and the system one often takes e dentulous impressions that cannot be improved upon with final impressions trays when there are large bulbous ridges.
I will start using the neocolloid injected with a hydrogum or tropicalgin base....Ill let you know how that turns out because it just might be the good replacement for the accugel.I use virtual and I get good results.

Did you use a spacer to make your custom tray?View attachment 16710
Ok took a nice one today. Here it is. I used a custom tray and Coe-Flex from GC America.
I might still be inclined to do a custom tray with a 3mm spacer for an alginate final imression....I have had a few lock on to mandibular undercuts using pvs...I use virtual and I get good results.

Big fan of Kromopan.We've been taking Preliminary impressions with Alginate in stock perf trays, then I construct Permanant denture bases for the vod. If the retention is good it all good, if it's less than satisfactory, we use rubber base (permalastic reg) as an impression and reline after finish. If the Pt admits to using denture adhesive at the initial consultation then they get a tissue conditioner put into their existing prior to prelim impressions and if they say something like "Place X, couldn't get it right and finally said that was all they could do for me" then we just assume it'll be a functional impression with hydro cast instead of rubber-base impression.
We've tried Alginot, and I just wasn't impressed with the results (way too many pulls and voids),Kromopan100 stays stable for 100 hrs so why mess around with more expensive materials that yield inferior results? I wish Kromopan100 came in regular set.
I will do something similar. I will take preliminary impressions using hydrogum 5 and if necessary take a secondary impression using the longer setting neocolloid....Then do a putty bite registration witht eh patient looking up at the cieling and at the same vertiacal as thier original dentures....I will also take impressions of thier existing dentures both outside and inside and make stone models of them for reference...a wealth of information there....On the second appointment I will do border molded impressions in silicon in a custom tray with a pin tracer and upper anterior bite rim..and register that with plastogum.....I will capture a facebow reading with that....Provided I have no interferences I will proceded to the pour-up using box and beading with the silicon impression on a lght cured baseplate...From there it goes to full new baseplate with light cure and then do a full setup in wax...which I try in and do a tissue condiitoner such as coe soft or co comfort and or hydrocast with a microseal base reline as a functional reline on the third appointment....Provided the patient likes what they see, I will process it just like that....via a Ivobase processed denture....rarely have any adjustments or sore spots...and I mean rarely.....We've been taking Preliminary impressions with Alginate in stock perf trays, then I construct Permanant denture bases for the vod.
