Figure 5 Top: Before applying the opaque, Kahng used GCâ€™s Initial Porcelain Tiâ„¢ Bonder kit to apply a thin layer of the titanium bonder to the framework. The bonding material is importantâ€”it makes all the difference between a well-bonded restoration and one that doesnâ€™t bond at all. Bottom: The framework after firing and sandblasting.
Figure 4 Kahng placed the framework in an ultrasonic machine with distilled water for five minutes.
Figure 3 Next, he sandblasted the inside of each coping on the framework.
Figure 2 Two days later, Kahng received the milled titanium framework and prepared it for porcelain application. He ground the copings using a Komet carbide bur especially designed for titanium; for best results, grind the coping in one direction only.
Figure 1 Kahng scanned the model using the NobelProcera scanner, designed the three-unit titanium bridge and sent the file to Nobel Biocareâ€™s centralized milling center in New Jersey.
