Instructions for use 2548 49 ridges on the labial side deserve maximum attention.Defining or moving the mesial and distalmarginal ridges defines the width of the tooth orallows you to influence the shape of the tooth,that is, to give it its basic shape. By positioningthe ridges in an appropriate manner, the dysharmonybetween the shape of the preparation andthe shape of the tooth that is so frequently encounteredcan be compensated for.Other structures of the labial surface – growthridges or similar – are usually weakened in agedteeth, due to years of natural abrasion. Agedteeth often exhibit a very smooth and homogenousenamel surface that needs to be replicated(Figure 49).51The next firing step is glazing. Through well-considereduse of paints and glazes, different shades,different types of lustre and other characteristicscan be achieved. It is important when glazingthat you determine and adjust your own glazingtemperature as a function of how the sur facewas prepared (polishing, application of glaze).The temperature shown in the tables can only bea rough guideline. Any minor correction requiredin the marginal region can still be performed afterglazing using the final margin materials that fuseat 680 °C. This is approximately 120 °C below theglaze-firing temperature, so that the rest of therestoration remains completely stable.The completed restoration (Figures 50 and 51)clearly shows the different effects. The anatomicaltubercle and the cervical region are characterizedby power chromas. The incisal region is a fineexample of opal effects, which have remainedstable during subsequent firing cycles. The trans -illuminated mesial and distal flanges show anatural bluish opal visual impression. All in all anexcellent shade composition. Thanks to Kiss.
