ABUTMENT SELECTION
5. Select
the proper Conical Abutment collar height for each implant by measuring
the tissue depth on the buccal side at each location. If a 1mm
subgingival margin is desired, subtract 1mm. Next, select the proper
abutment angulation; straight, 17º or 25º. Allow approximately 2mm of
interarch distance space between the top of the abutment and the
opposing occlusion. Finally, match the color of the implant analog to
determine the platform diameter.

6. Place the selected Conical Abutments into each analog. Line up the hexes and press firmly until feeling and/or hearing the audible and tactile click. Secure the abutments into place using the Conical Abutment Screws and the Abutment Driver. |
PROVISIONAL RESTORATION FABRICATION 8. Drill
holes in the vacuum formed template in the areas of the Conical
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. or Duplicate
the master cast with the Conical Abutments and temporary cylinders in
place. Articulate, wax the provisional on the duplicate cast and
process it in acrylic resin.
7. Select
the appropriate Conical Temporary Cylinders for single or multiple
units. Place a Conical Temporary Cylinder on each of the abutments.
Secure the cylinders into place using a retaining screw and the Large
Hex Driver.
9. Clear
the cylinder access hole and remove the retaining 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 these and removed easily. Fill in any voids. Finish the
crown or bridge to the desired contour and polish.

12. If a flap procedure was used during surgery, suture the tissue around the Conical Abutments. Place acrylic resin into the retention facets on the Conical Temporary Cylinder and into the cylinder area on the provisional. Seat the provisional over the cylinder and secure it into place by threading a retaining screw through the lab processed cylinder. Have the patient close into occlusion. Allow the acrylic to set per the manufacturer’s instructions. Remove the retaining screws and remove the provisional. Place the remaining Conical Temporary Cylinders on the abutments 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 Gold-Tite® Retaining 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. |
