Basic procedure - Implant
retrieval instruments
Implant Retrieval Instruments are indicated for use
to remove osseointegrated dental implants withdamaged connection interfaces or fractured body byengaging the implant inner threads, enabling rotationof the implant so that it can be removed.
Implant Rescue Collars are indicated for use inconjunction with Implant Retrieval Instruments for
implants with an Internal Tri-Channel connection, when
the connection is collapsed and to prevent expansionof the implant collar when removing the implant.
In situations where the implant cannot be removed
with the Implant Retrieval Instrument alone, due tostrong osseointegration or other factors, refer to theadvanced procedure on page 15.

2 Place Trephine Drill‒ Remove any abutment or prosthetic
components from the implant.
‒ Place the Trephine Drill over the implant.

3 Drilling
Start the drilling procedure using low speed(60 – 100 rpm) and copious irrigation. When theTrephine Drill grips into the bone, the speed can beincreased (1200 – 1500 rpm).
Warning Do not apply excessive pressure to theTrephine Drill as breakage can occur.
Warning During the drilling procedure, care must be
taken to prevent damaging adjacent vital structuresdue to the increased width of the implant which is
being removed. It is recommended to use the depth
markings on the Trephine Drills as reference points inorder to ensure that the drill does not progress deeper
than planned and risk damage to vital structures.
Caution Ensure steady handling during use of theTrephine Drill as it may abruptly jump sideways before
fully surrounding the implant.
Caution Copious irrigation is important when using theTrephine Drill to avoid overheating.
Note The Trephine Drill can wear out during use. If
the cutting efficiency is poor, the instrument should
be replaced.

Abutment Retrieval
Instruments Zirconia
The Abutment Retrieval Instrument Zirconia CC isused to remove zirconia abutments. It is comprised of
two pieces: an engaging pin that is placed through thescrew access hole of the zirconia abutment/prosthesis,
and an activating needle that is inserted through theengaging pin. After using forceps to compress the twocomponents, the engaging pin engages the abutment
and lifts it vertically so that the abutment can beremoved by hand.

1 Remove abutment screw‒ For abutments without adapter (A), remove theabutment screw using the Unigrip Screwdriver.
‒ For abutments with metal adapter NobelProcera
ASC Abutment (B), remove the abutment screw
using the Omnigrip Screwdriver. The metal adapter
stays in place.
Note The abutment screw must be unthreaded
from the internal threads of the implant. If theloose abutment screw is difficult to remove, use asmall amount of sticky wax on the tip of the Unigrip
Screwdriver, which will aid retention of the abutment
screw head.

2 Insert engaging pin‒ The abutment retrieval instrument consists of twopieces, engaging pin (I) and activating needle (II).
‒ Insert the engaging pin into the abutment / metal
adapter of the abutment until it reaches a stop.
Note The engaging pin has to be pushed in rather
firmly to reach its end stop. There is first an intermediatestop that has to be passed before the pin is in final
position.

Abutment Retrieval
Instruments Titanium
The Abutment Retrieval Instrument Titanium CC and
Abutment Retrieval Tool Nobel Biocare N1 TCC are
indicated for use to facilitate the removal of titanium
abutments from a dental implant.
By applying torque with the screwdriver, theunthreaded portion of the pin comes into contact with
the implant, which pushes the abutment up so that it
can be removed by hand.

1 Remove abutment screw
Remove the abutment screw using the Unigrip
Screwdriver.
Note The abutment screw must be unthreaded fromboth the internal threads of the implant and theabutment. In case the loose abutment screw is difficult
to remove, use a small amount of sticky wax on the
tip of the screwdriver which will aid in retention of theabutment screw head.

2 Insert Abutment Retrieval Instrument
Insert the Abutment Retrieval Instrument Titanium
into the abutment and screw it into place using the
Unigrip Screwdriver until the tip of the screw touches
the bottom of the hole inside the implant.

3 Release abutment
Apply torque to the Unigrip Screwdriver or the
Omnigrip Mini Screwdriver to release the abutment
from the implant. Turn the screw clockwise and, as thethreads of the screw are designed counterclockwise,
the abutment is lifted.
