When the shade is not spot on…use the try in pastes to help enhance the match…or base only….just turn off dental light and headlight…no “oops” setting of the bond!
XL brightens, A4 or A3 warms to more yellow…
When taking shades in the esthetic zone, it is helpful to arrange your Vita shade guide in order of descending value rather than shade grouping.
Cut off the gingival 1/4 of the shade tabs since they are more deeply stained and not indicative of the true shade.
In addition, if you have a window nearby, have the subject stand near the window while you and your assistant match the tabs according to value in indirect light as well as direct light.
Follow this initial shade selection with a stump shade match after prepping. This will then get you closer to the final desired shade and allow you to select the appropriate block of material which can then be custom stained if necessary when trying it in.
Lastly, the Cosmedent system has true color try in gels and cements if you need to shade modify through cementation.
Good tips. I find that for veneers, typically Variolink Value +1 cement will give me a true color to the veneer shade milled after cementation with any “stump” shade from Nd1-Nd4. Once past ND4 I have to use at least a Value +2 to start to equalize for a darker tooth shade.
I like to use a combination of the vita easyshade and shade tabs to pick up any areas of characterization. 1)I use the easyshade to get the cervical body and incisla shades of the tooth or teeth. 2) I use the my shade tabs under room light, by the widow and with 5500k light. This allow me to se if there is any color variation that I can pick up and possibly add with staining. And, unless the tooth has staining I use a translucent cement.
Lee Culp when he presented at the Business of Dentistry Las Vegas event talked about how whe uses only one shade, the enamel high transluscency OM series for most veneers and most crowns. Personally surprised. He went on to explain, since these shades and transl. blocks duplicate most folks enamel, he then just works in character and color nuances via external and then minimal internal staining. He acknowledged he has all the time he needs to play with shade, since he is not involved in me appointment cases.
Yacman, that is why I like working with the higher translucency blocks too. I find them so life-like in most cases. I had posted my disappointment that only LT blocks were being made for bridges. I think that is a mistake, but I’ll have to give them a try.
Charlie, at every occasion at each conference we attend, we take the time to chat at each manufacturers’ booth.
Relate to them the desire for just that, HT EMax blocks…if we all ask…we all will eventually receive…
