Magnet Instructions |
Benefits:
- No abutment
parallelism required. Corrects up to 24º
divergency.
- Lowest force
application on abutments.
- Applicable for direct
placement into root, cast coping for root, or custom keeper for implants.
- Easiest patient
insertion and removal--no path of insertion.
- Space friendly--2
sizes available.
- Double encapsulation
ensures no corrosion.
- Concave/convex
relationship between keeper and magnet provides lateral stability.
Placing the keeper

 |
| Pilot Diamond |
Sizing Diamond |
Toothpiece |
Root supported: refine the canal with the pilot diamond.
Use the sizing diamond to create the recess for the keeper. Cement the keeper
into the prepared root. Do not allow cement above the groove in the keeper, so that
the impression piece will fully seat over the keeper. *You may also fabricate a cast
coping with precious metal by waxing up to the groove line on the keeper.*
Implant supported: Select and order the custom implant
keeper by providing the following:
Implant manufacturer, and the diameter of the implant
Platform: flat, external hex, internal hex, etc
Cuff height: beginning at 2.5mm and increasing in 1mm increments
Place a drop of Ceka Bond adhesive on the threads and use the hex tool to
thread the keeper into the implant.

| The white impression/processing piece indexes to the keeper ( root or
implant) and is pulled in the impression (FIG
1).
Please note: Impression taking for
implants. Implant keepers are subject to undercuts that
need to be eliminated. Red and Blue blockout
rings are provided with each implant keeper.
Place the blue ring around the keeper to fit closely to the gingival tissue. Index
the white impression piece to the keeper. Check for exposed metal on the lateral
(side) walls of the keeper. If metal is exposed, place red rings until all exposed
metal is covered. This eliminates impression material from entering undercuts and
preventing the seating of the black keeper analogue into the impression. Besides
eliminating undercuts that can lock the prosthesis into place, the rubber rings also
creates a flared opening (funnel) in the prosthesis for easy magnet insertion.
Next, index the black keeper analogue in to the white
impression/processing piece in the impression (FIG 2). |

| DO NOT PROCESS DIRECTLY TO THE MAGNET!
The use of the rubber blockout rings will provide a flared
opening in the acrylic for easy magnet insertion. Once the acrylic is set, you may
remove the processing piece and insert the magnet (5 & 6). |

| Place the blue
rubber
blockout ring around the keeper to fit closely to
the gingival tissue. Index the white impression / processing
piece to the keeper. Check for exposed metal on the lateral
(side) walls of the keeper. |

|
| If metal is exposed,
remove the white processing piece and add red
blockout rings until all exposed metal is
covered. DO NOT PICK UP THE MAGNET in self curing resin.
Using the rubber blockout rings will prevent the white processing piece from becoming locked in
the prosthesis, while providing a flare for easy magnet insertion. |

Cut a small vent hole in the denture to allow excess
acrylic resin to escape. Do not have the patient bite. Use
finger pressure only directly over the magnets. Let the acrylic
set. Using the blade end of the tool, unthread the white impression/processing piece from the
prosthesis (FIG 5). Use the other end of the tool to thread the Smart magnet into the
prosthesis (FIG 6). Do NOT force magnet in to the
prosthesis--remove any resin flash if necessary. Do NOT over
tighten the magnet in to the prosthesis as this will crack the housing. Light finger
pressure is sufficient to place the magnet.
Intimate magnet to keeper contact is necessary for retention (eliminate
air gaps or spaces). The magnet may be vertically adjusted by threading the magnet
up or down 1/8 of a turn at a time. Do not have the magnet in premature contact with
the keeper as this will cause excessive loading of the magnet. |
