How to Fabricate An Esthetic Porcelain- To-Titanium Restoration

Luke Kahng, CDT · Technical · Jan 2012

  • Figure 1 Kahng scanned the model using the NobelProcera scanner, designed the three-unit titanium bridge and sent the file to Nobel Biocare’s centralized milling center in New Jersey.

  • 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 3 Next, he sandblasted the inside of each coping on the framework.

  • Figure 4 Kahng placed the framework in an ultrasonic machine with distilled water for five minutes.

  • Figure 5 Top: Before applying the opaque, Kahng used GC’s Initial Porcelain Tiâ„¢ Bonder kit to apply a thin layer of the titanium bonder to the framework. The bonding material is important—it makes all the difference between a well-bonded restoration and one that doesn’t bond at all. Bottom: The framework after firing and sandblasting.
