I've got two similar cases on the go at the moment upper 4321/1234 veneers. One is prepped with a 1mm shoulder at the margin, no discoloured preps and a desired shade of B1 The other isn't prepped so heavily at the margin, slightly discoloured preps and desired shade of OM2 I'm thinking the...

I’m struggling with a custom shade. It started in the usual way of the Dr choosing A2 for the shade. Needless to say that was way off. I eventually get to see the patient and the shade is a C2C3 but with a really translucent overlay all over the tooth. I just can’t get the translucency over...

I've been using Sintron for two years up till now problem free. Over the last month or so I've had porcelain cracking mostly on single wing marylands and cantilever bridges. The designs have more than adequate support. In the last week the problems got worse. Everything today that I built up on...

I know there is a similar thread running on this. I’ve got 3-3 case of wrap around veneers. I’ve milled three times but the results are poor. I’ve got the edge set to 0.2mm to give some thickness but I’m getting a lot of chipping. The nature of the preps makes some undercut areas, so fitting the...

I’ve been using Initial MC for 3 yrs or so. I’m getting lots of steam tears/ shrinkage that I haven’t experienced before. I can’t think of any thing that I’m doing differently to cause an issue. I also use Initial ZR which fires perfectly. I’ve tried building up with water and with build up...

I've got a client that likes to use temporary cement on his cement retained implant cases. This works ok for metal ceramic cases as the friction of the metal framework internally aids retention. Zr cases cement with temp cement just pop straight off. I'm looking at Ti Bases as an alternative...

Is there anyway of designing screw retained bridges with AG's version of Exocad in one piece ie not using the cementable interface? I can design single abutments using the Ti "Form" option but this is for the premilled blanks only.

Anybody got a Ney Q50 pressing furnace. I've got one that I dug out of storage and fired up at the weekend but I cant remember what vacuum level (mm) that it's supposed to achieve.

I'm looking for a sinter furnace, I'm thinking either the Nabertherm LHT 02/17 LB Speed or the Mihm Vogt HT speed. Any feedback on these ovens?

I'm looking at the green state CrCo available and the various sintering ovens available. I've seen a couple that can sinter CrCo and Zr, one made by Degudent the other by Zirkonzahn. http://www.dt-shop.com/index.php?id=22&L=1&artnr=21929&pg=12&aw=074...

I don't have a mill but I'm thinking of getting one. I see people milling screw retained bridges on Yena machines with success. What is the position with milling implant abutments? I know that premilled blanks are available with the interface/connection already finished. Is it possible to mill...

I've got the GC Initial Bleach shad kit, is it matched to a particular shade guide? I've compared the dentine tabs on the shade wheel in the kit with the Vita 3D bleach guide and it seems like a reasonable match. Any other suggestions?

I've got an implant case with four abutments on a solid model. Is there anyway of scan the individual abutments and then registering into an overall jaw scan? I've tried every variation that I can think of but no joy. I can locate one abutment ok, but if I try to register another one it alters...

I'm doing a cast implant beam for a client that decided he wanted it NP. I ordered some Cr/Co alloy from Bredent. All cast well, albeit apart from a slight rock. I sectioned and laser welded back together which is were the fun started. I always tack together on opposing quadrants, then seam...

What metal are firing pins made of? I'm forever losing them, easy to make some just bend some wire. but what wire?

What's the word on Vaniman stone vac extractors? Good or avoid?

I've got a case that's just arrived in the lab for a screw retained denture on Bredent Fast&Fixed abutments. Unfortunately we haven't been involved in the planning stage, the patient has a temporary denture that we are supposed to copy but we don't have an imp of the denture just a silicone...

Hi, I've got a case in for a root cap for a P/ and the Dr has indicate that they want the Dyna Magnet system used. The patient only has one standing tooth on the UR1, the root cap is to made on the UR3. Normally when I've done root caps before they were done in pairs (eg 3/3 etc) is having a...

Ok, how about we all compare scan speeds for the various scanners that we use? Maybe have a few bench mark scans: 1) single die 2) single die plus adjacent teeth and putty squash 3) three unit bridge plus adjacent teeth and articulated opposing model

Hi, i'm just upgrading my pc, currently running Exocad Version 5058 , what version of windows 7 (or 8?) do I need 32bit or 64? or doesn't it matter? Adam
