Ceramic thermal barrier coatings TBCs are now widely used in aircraft and power generation turbines to shield engine blades and other metal components from high temperatures. A new generation of engines will exploit these coatings to enable even higher operating temperatures. A significant difference was observed among all groups P <.05 for the microleakage between the bracket-adhesive interface. Metal brackets exhibited significantly more microleakage than did ceramic brackets between the bracket-adhesive interface with either of the adhesives. Clearfil Protect Bond exhibited results similar to Transbond XT.
