SPECIALNIH VEZIV, ki preprečujejo nastanek
oksidanamejni plasti med titanom in keramiko
in hkrati zagotavljajo povečano trdnost spoja.
Lenz, Blume 1997
Vezivno območje„ Ti Bonder - titan ” kažetesen stik med
keramiko in titanom.
Duceratin 85 N/mm2
TiBonder 68 N/mm2
VitaTi Bond 57 N/mm (norm 25 N/mm2 DIN 13 927)
Ti Bonder in sodobnekeramikezatitan močno omejujejo
in preprečujejo nastajanjeoksidneplasti med kovino in
keramiko.
Trdnost vezi titan- porcelan lahko primerjamo strdnostjo
vezi plemenitih zlitin in keramike.

A. Psoch, A.Stadler, J. Setz, 2006
Raziskave kerami nih konstrukcij na rezkanihč
titanovih ogrodjih po 12 mesecih nošenja.
Po 12-mesečnem opazovanju 34 pacientov s
162 enotami rezkanih ogrodij v celoti
fasetiranih s sodobno titan-keramiko je bil
ugotovljen občutno nižji delež neuspehov kot
pri uporabi starejših ulivalnih postopkov in
materialov.
Rezultati so bili primerljivi s keramičnimi
prevlekami na zlato-platinski osnovi.
