Figures 25 - 27Then we covered the dentinelayers by incisal enamel andbegan working on lustreporcelain. Forming of mesialaspect is started with bluelustre porcelain, then LT-Nor LT-0 was applied—that iscalled a technique of lateralsegmentation. If we wanted toimitate a lateral crack, we couldform that zone sharper usingbrush or cutter and apply stain.Figure 28There are special brushes for thatpurpose, which allow techniciansto apply the material very finely,avoiding its penetration into thetaken layer. Porcelain should belaid very clearly on the edge ofceramics.26. 27.28.Figure 29For the photographic effectacquisition, I had to emphasizethis dye. The layer is in fact verythin, but I have shaded it bymarker ink pen.Figures 30 and 31Afterwards, we made the socalledwindow. For this, we usedmore clear transparent material,in this case LT-0.29. 30. 31.March 2011 Journal of Dental Technology 33
34.32. 33.35.Figure 32Then we worked with cream-colored tone, forthe distal aspect always is less transparent andis lighter. Cream enamel suits best of all for that.We finished shaping with LT-1 and formed toothcontour more clearly.Figures 33 and 34After that, we removed the die from the modeland shaped the proximal zones. Usually, theyhave more intense color. We placed orangeinto the contact zone, after which firing wasconducted.36.Figure 35After firing, we had this material structure. So asto not to lose all the restoration effects, a verythorough approach to the program choice wasrequired. Burning temperature could not betoo high. Otherwise, we would have gotten themelted surface (as one of candy). Underbakedceramics was also not acceptable. In this case,temperature is 925 ° with 30 seconds exposure.As a result, the surface has sugar texture. Alleffects are clearly visible and transparency is notcompromised.Figure 36After that, we contoured and corrected asnecessary.37.34 Journal of Dental Technology March 201138.Figure 37We treated it using traditional method, withdiamond stones, to create the suitable texture.For better visualization, we used ink pen or pencil.Figure 38After glazing, the surface is polished with thespecial polishing agents, in this case Pearl Surface(Noritake), which created natural shine andprovided teeth with a realistic appearance. PearlSurface exists in two variants: for final polishingand for preliminary polishing.
