Hi there, I do a fair amount of Zirconia abutments cemented to Titanium bases. I've had one (now former) client who has had a few that I've done for him where the Zirconia has debonded from the Ti base. Out of the hundreds I've done this has only happened with this one client. Have a guess whether this is frustrating the hell out of me. I've looked back at my records and there has always been other Zirc to Ti base jobs done for other clients at the same time as these problem ones and they are all still there causing no problems. I always check use by dates and use the correct materials i.e multilink, monobond etc.I know there's a whole raft of techniques and materials with which you can enhance the bond between the Ti base and the Zirconia but considering this has happened with only one Dentist, has anyone had an experince like this, and can anyone suggest a reason for this?
Also, I have one to fix now. It has an emax crown cemented to the Zirconia abutment. Can anyone suggest a way of removing the emax crown from the Zirconia? I've tried putting in the furnace to 400C to break down the cement in the past but the emax cracks.
