Ivocolor re-revisited.

No that I have drug my self away from the pool in Dallas (see Skramy's post for reference) here are some cases with the ivocolor that I did last week.  

The first case is an extra bridge I had laying around that I use to test glazes on.  So it was already sintered and just need esthetic enhancement.  This a the same bridge using two different lighting scenarios to show the optics.  This is straight out of the oven and allowed to cool.  As you can see it is similar to the GC luster paste in that it looks a little grainy.  

Here it is after polishing. 

Now of course these are out of the mouth so how does it look in the mouth. 

Here is a case of two centrals.  

The patient had a very dark stump shade on #9

These are MT blocks for the finals.  There was an opaquer used on the stump to help block out the color. 

Glazing after already sintering is the current recommended method by Ivoclar.  What we are actually testing is how does it look and survive with a single firing in the blue state.  Let's take a look. 

This is a crown my assistant did in a single firing.  She did say she went a little crazy playing around with the brown in the grooves

Here is one that I did on an HT block in a single fire.  I would have had pics in the mouth but the patient's tissue was bleeding like crazy after clean up. 

And here is one fired and put in the mouth.  

My take on this material is this.  It applies very nice.  The colors stay in place and don't tend to get a blotchy.  I am still working on the consistency of the glaze(which has to be cut with liquid) and essences ( which come as powders).  However the colors are vibrant and gives a nice natural look to the restorations.  

When two fires are used you get a little bit of grainy look to it, that could be from my consistency of my mix, but with a little polish you get a nice texture that looks natural.  Very similar to luster paste.  

When you single fire you get a nice glassy glaze.  This is a low fusing ceramic so when by firing it on the higher Emax cycles you are heating the glaze way past its melting point so it becomes very smooth upon cooling.  

Also because it is a low fusing porcelain you can use it on any material that we currently glaze.  For anterior's you get something very similar to Luster Paste and for posteriors with a single firing you get a glaze that is almost as glassy as the Identco spray glaze.  Also since it is low fusing you can use the liquid glaze with the P3 faster fire cycle.   

And yes you can use it on the new Zirconium.
