Retentive Strength At The Zirconia Implant Abutment And Titanium Base Interface With Different Surface Treatments, Celin Arce
All ETDs from UAB
Screw-retained zirconia implant crowns with an internal titanium base have favorable mechanical properties compared to single piece zirconia implant crowns; however, they require adequate bonding between the zirconia crown and the titanium base. This study measures the retention between a titanium base and a full contour zirconia implant crown following different surface treatments of their bonded surfaces. Full contour zirconia implant crowns were fabricated to fit a 3.5mm titanium base. The crowns were bonded to the titanium bases following 4 protocols (n=15): no surface treatment (Group 1), MDP-primer on the intaglio of crown and exterior of base (Group 2), alumina …
