How to Use the Abutment Retrieval Kit by Nobel Biocare™
The great thing about modern implants is that the abutments have been engineered to stay in place once they have been torqued down. But sometimes you need to remove an abutment that has already been torqued. The Abutment Retrieval Kit from Nobel Biocare™ is designed specifically for such instances.

This abutment removal kit includes specific tools that allow dentists to easily and predictably remove abutments from integrated implants in their patients’ mouths. However, it’s important to note that the kit is only designed to use on Conical Connection implants.

What You Need to Know About the Abutment Removal Kit
Inside of the Abutment Retrieval Kit, you’ll find three different types of tools. They can only be used on your implant if the abutment screw has already been removed. If the screw is broken, you will need to use a separate screw retrieval kit before proceeding with using one of these abutment retrieval instruments.
Types of Implant Abutment Removal Tools
The first tool in the Nobel Biocare™ Abutment Retrieval Kit is called an Abutment Release Pin. It’s compatible on all Nobel abutments and is quick and easy to use. Usually, a release pin is going to be the best tool to start with, regardless of your abutment type.
Abutment Release Pin
To use the release pin, insert it into the abutment and then gently rocked it back and forth to loosen the abutment from the implant. Once you feel the abutment start to loosen, it can usually be lifted out of the implant.

The other two tools in the retrieval kit are each designed for specific types of abutments.
They include the Abutment Retrieval Instrument Titanium and the Abutment Retrieval Instrument Zirconia.

The Abutment Retrieval Instrument Titanium is specifically made to use with NobelProcera CAD titanium abutments with internal screw threading.

The tool looks like a normal dental implant screw, except that it's taller and the threads are higher up on the screw body. It’s designed to be able to screw into the abutment itself. Once fully inserted, the bottom of the retrieval device comes into full contact with the bottom of the implant screw hole, at which point it forces the abutment up and out of the implant.

Remember, this specific retrieval tool will only work for titanium abutments with internal threading. If you have a full zirconia abutment or a zirconia abutment with a titanium base, you will want to use the Abutment Retrieval Instrument Zirconia.The zirconia tool is a two-piece system that’s comprised of an (1) engaging pin and (2) activating needle.
To use this two-piece removal tool, you will separate the pieces and then insert the engaging pin into the abutment until it comes to a complete stop.
Next, insert the activating needle into the engaging pin. Push down firmly until the top of the needle is completely flush with the top of the engaging pin.

At this point, you may need to use hemostats to help get these two pieces to fully mate. This essential process activates the wings of the engaging pin, so that they are completely locked underneath the bottom edge of the abutment interface.
Once the two pieces are fully engaged, you can lift out the engaging pin, which will then pull the abutment out with it.
