Stain and glaze question

[Al.]

This is what I mean by matte, semi gloss may be a better discription.

Picky Drs I work with that take pics of their work complain about too high a paint on glaze not matching the patients natural teeth.

Once again Al. great work.

Do you mean natural teeth that are dehydrated because the mouth was open to long, which look very dull or do you mean after they are rehydrated, which tends to bring back the gloss finish.
Also, you realize that porcelain doesnt react like natural dentition, then you add the saliva effect that makes teeth look more glossy.

AL1, if I may. I think it would make sense to have the surface texture and finish of a dried natural tooth so when saliva is added to the equation it affects both surfaces the same. "Texturewise only". Shade, value and translucency should be that of a hydrated tooth.

Doug,

Thanks for the hint on the double glazes, may take an old crown stain, 2X glaze and take a prophjy jet to it. An interesting project . . .

and Al thanks for the pictures, I'll see if I can get the girls to let me take some close-up pics

what i do when im taking shades is after ive got the photos with the tabs, i get the patient to wipe across the tooth with their finger to remove any moisture.

Then i get a couple of snaps of the tooth in that state so i have a good indication of surface gloss. Its also handy if you put a tab in that photo as well, so you have a reference for surface gloss to compare.

This is the luster that works best for me on a multi unit case. Gives nice subtle light reflection and looks very natural once saliva is on the teeth.

another good example of surface finish/glaze

Crown 8 and veneer 9, both emax fully layered
Patient 18 year old female

here you may think that the luster is to low..

then in smile view with saliva



these were both glazed with glaze powder/liquid, so for those that say this leads to overglazed and fake looking crowns, maybe this will make you rethink

Hey Paul, nothing like spit to give it luster.
You nailed the surface texture and shade....love those incisal notches, makes them look so natural.......

No Charles, those incisal notches aren't just natural; they're downright sexy.

Had a interesting conversation with a technical guy from Jensen. As we've all come to the conclusion, a Prophy jet is a big no no. One thing he did bring up, and I've never heard before, is that if the oral environment is a real acidic one, that could seriously compromise the glaze\stain, and actually leave a pitted surface. He says glaze -- glaze is an alkaline formulation, which in an acidic environment would quickly erode.

Unfortunately, it's too late to get pictures of the surface texture of one set in an anteriors. Dr. had polished them using rubber wheels, and actually look quite nice despite the fact of the gingival color is gone.

Paul.

Thanks for your pictures, they're awesome.

Thanks, had a questions from dmonwaxa regarding the slight greying at the neck of no 21 (just to confirm this is no9 in US charting?).

When you see where we started from with this case i think this will explain it..

The Stump was ND9 and was a hell of a job masking with an Emax MO CAD frame. If id had the press then the MO from press would have been better or perhaps even a HO. We had to prep no9 by around 1.5mm in the end to mask.

Very Nice Paul, great job displaying how texture, reflection, and the luster play such a vital role in anteriors.

 

[dmonwaxa]

Great job Paul.
