How to remove a broken Ankylos abutment?

Last Updated: Sep 19, 2016

I have a case where an Ankylos Regular C/ abutment non-indexed, is broken into 2 parts which are still held together by the abutment screw. It fractured right at the implant platform. The apical conical part is still stuck inside the implant and the coronal part (with the crown still attached by cement) is freely rotating after I unscrewed the abutment screw. Despite using different retrieval techniques, I was unable to remove it. It looks like the conical part that is still inside the implant is “fused” with the implant due to such a good Morse taper fit of the conical connection. I even used the Kavo Coronoflex crown remover system to try to dislodge this conical part (by grabbing onto the crown) but to no avail. I don’t want to keep using the Coronoflex for fear of breaking the abutment screw, which is the only thing that provides leverage to dislodge the stuck conical part. Any suggestions for how to remove this?

Ankylos has a repair kit that you will have to get from your Rep. It will come with a booklet and hopefully they give you a usb as well that has vidoes on it. Each part of the abutment and screw needs a separate driver. Make sure you book in lots of time. It is really hard going. And the morse taper in the end is always hard to break loose as well. Just keep breathing and you will get there.
