PreFormance® Temporary Cylinders
Single Or Multi-Unit
ABUTMENT SELECTION
5. The
PreFormance Temporary Cylinders are designed to allow acrylic resin to
be added to them to develop the desired subgingival and supragingival
contour to the crown or bridge. The hexed cylinder is used for single
units and the non hexed cylinder is used for multiple unit provisional
restorations. Match the color of the implant analog to determine the
platform diameter.

6. Place the selected PreFormance Temporary Cylinders into each analog. Secure the abutments into place using a Certain® Titanium Abutment Screw for hexed cylinders or a large diameter titanium abutment screw for nonhexed cylinders and the Large Hex Driver. |
PROVISIONAL RESTORATION FABRICATION or Duplicate
the master cast with the PreFormance Temporary Cylinders in place.
Articulate, wax the provisional on the duplicate cast and process it in
acrylic resin. 8. Clear
the cylinder access hole and remove the abutment screw from the
selected cylinder. Remove the template from the cast over the
non-processed cylinders with the selected temporary cylinder inside the
acrylic. Remove the provisional from the template. Remove all excess
acrylic from around the margin areas of the provisional. Relieve the
holes for the other cylinders as necessary so the provisional can be
placed over those and removed easily. Fill in any voids. Finish the
crown or bridge to the desired contour and polish.
7. Drill
holes in the vacuum formed template in the areas of the PreFormance
Temporary Cylinders. Place the vacuum formed template on the master
cast over the temporary cylinders. Reduce the cylinders as necessary so
these fit within the template using a carbide bur. Seal the cylinder
access holes with wax or putty. Select one cylinder in an area with
dense bone to process into the provisional. Block out the retention
facets on all other cylinders with wax. Place the cast back on the
articulator. Add acrylic resin into the retention facets on the
selected cylinder and fill the tooth portion of the template with
acrylic resin. Fully seat the template on the cast over the temporary
cylinders using the articulation. Allow the acrylic to set per the
manufacturer’s instructions.

11. Place acrylic resin into the retention facets on the PreFormance Temporary Cylinder and into the cylinder area on the provisional. Seat the provisional over the cylinder and secure it into place by threading an abutment screw through the lab processed cylinder. Have the patient close into occlusion. Allow the acrylic to set per the manufacturer’s instructions. Remove the abutment screws and remove the provisional. Place the remaining PreFormance Temporary Cylinders on the implants and lute these into the provisional by repeating the prior steps. Fill in any voids. Remove any excess acrylic and polish. Screw the provisional into place with the titanium abutment screws using the Large Hex Driver. Torque the screws to 20Ncm using the Large Hex Driver Tip and a torque device. Place a temporary filling material in the access holes and seal those with composite resin. Adjust the occlusion as indicated. If a flap procedure was used during surgery, suture the tissue around the provisional. |
