Bredent B&C Speed works nice for me. Crowns tend to be slightly tight, but is dimensionally stable and perfect for long span bridges. Smooth! Fujivest Premium I use for solo crowns and small span bridges. Never had micro bubbles problem, but I did notice that smoothness is better if I don't use...

sndmn2, I have the same one! Spring broke 2 (or was it 3) times already. It can be repaired, you simply shorten it (it brakes at the end where one screw holds it). It then goes a few more years. I also would like to know where to get a spare one!

Zirkonzahn just released a new video, e-max milling with Zirkonzahn M5: Nass-Schleiffunktion - Zirkonzahn GmbH

I think those are the results of the study: Flexural Strength of YPTZirconia Sintered Using Conventional and Microwave Sintering

Charles, what is the cost for Origin scanner (or Girrbach)? ZirkonZahn sent me an offer for their scanner, PC, screen and software based on Exocad for 20.370 with VAT.

With all due respect, I don't understand why no one is considering Zirkonzahn. On specifications their scanner AND milling unit have better performance then Girbach, in the scanner you can put the whole articulator and scan the relation like this, no special mounts like with Girbach! Not to...

I told them I can't compete with the prices other local labs provide to him. I attach the new price list and he is gone.

:) Please don't be upset. We are just talking. Last year I had problems with 4 patients, 2 of them had removable total prosthesis (they were blood related and it seems both had mental problems, we relined, redid and again relined on remake, but they still couldn't accept it, we didn't charge)...

I on the other had believe that 0.25 is possible (if we are talking about remakes). If dental tech checks and refuses all questionable impressions, if he sees patient and is there with almost all phases, if he helps with choosing a color, ... I would say it is possible.

Yeah, but if you measure it it is 2,3 actually!

Isn't original big one 2,2 (measured 2,3 actually),why do you have 2,5?

I agree it is an important factor! I am one man basement lab as well, I would say my remake percentage is about 0.1 %, but I ask many times for another impression, I would say in about 5-7% of cases. In about 3-5% of cases I ask for another bite.

Ajel, interesting thoughts! I never though of that... I promise I'll weight it next time (I don't get many relines, maybe one or two per month),but I would say the packaging would be enough for some 20 or more of them. I get 25 EUR for it (32 USD),so putty would represent 45 grams or 3.6 USD...

Correct, but I do it without undercuts! This is why: sometimes the shape of the prosthesis will be such that it will be impossible to get the prosthesis out or back in to the putty. So I don't do undercuts so that I can lift putty out of the plaster and install prosthesis into it (after I...

It is interesting, that there is not much of a difference on the prep tooth, but there is quite a difference on the model as a whole. D800 has much more saturated net. Why is that? Are prep tooths scaned separately one by one? And why is data missing on D800, check palato incisal on frontal (a...

Patmo, would it be ok if you send me all your scanes and I'll upload them to the DropBox, or you upload them to your DropBox?

Labwa, can you send me some blue scans and I will upload paulg100 scans from the red to my dropbox? You can send them through this form: https://www.yousendit.com/dropbox?dropbox=scan

OK, the simplest solution is a DropBox: Dropbox - Simplify your life 2 Gb are free! It is a 2 minute work. You provide your name, email and password. You download and install application. You drop a file you want to share into a (Public) DropBox folder on your computer. File gets uploaded. On...

Patmo, do I understand correctly that 2 scans on the picture were taken with the lab scanner not intraoral scanner? Could you send me those 2 files please (I assume they are in STL)? I would like to see up close the margin area. Can anyone send me intraoral scan from Sirona (in STL)? my...

Carlos, don't you think full scan of the tooth (like MHT spectrafotometer) would be more adequate when taking color? I mean, the tooth usually is not composed of only one color but color fields...
