ABUTMENT SELECTION
5. Measure
the tissue depth in the interproximal areas at each location and select
the proper abutment collar height that will allow the margin to be at
tissue level or slightly below after preparation. Also, select the
desired emergence profile and a straight or 15º angled post. Finally,
match the color of the implant analog to determine the platform
diameter.

|
6. Place the selected PreFormance Posts into each analog. Line up the hexes and place the flat side of the post to the buccal. Press firmly until feeling and/or hearing the audible and tactile click. Secure the abutments into place using a Certain® Titanium Abutment Screw and the Large Hex Driver. |
7. Place
the vacuum formed template on the master cast over the PreFormance
Posts. Reduce the posts as necessary so these fit within the template.
Block out the undercuts on the adjacent teeth. Place the cast back on
the articulator. Apply a separator to the posts and the casts. Fill the
tooth portion of the template with acrylic resin. Fully seat the
template on the cast over the abutments using the articulation. Allow
the acrylic to set per the manufacturer’s instructions.
PROVISIONAL FABRICATION or Duplicate
the master cast with the abutments in place. Articulate, wax the
provisional on the duplicate cast and process it in acrylic resin.

9. Remove the template from the PreFormance Posts. Remove the provisional from the template. Remove all excess acrylic from around the margin areas of the provisional. Fill in any voids. Finish the crown or bridge to the desired contour and polish. OPTIONAL: Relieve each abutment area for the intraoral reline of the provisional. |

Place the implants using the surgical guide and following the surgical plan provided by the guide manufacturer.
POST SURGICAL DELIVERY OF PROVISIONAL
11. Place
each PreFormance Post into the implants, one by one, following the
tooth position numbers on the buccal. Press firmly until feeling and/or
hearing the audible and tactile click. Thread the titanium abutment
screw into each implant using the Large Hex Driver. Verify an accurate
fit of each abutment by visualizing the interfaces or take a
radiograph. Torque the abutment screws to 20Ncm using the Large Hex
Driver Tip and a torque device. Seal each access hole with a temporary
filling material. Try in the provisional over the PreFormance Posts and
verify it fits to the margins properly. Adjust the occlusion as
indicated and remove the provisional.

12. If the provisional did not fit passively, place acrylic resin into each abutment area, seat the provisional onto the abutments and have the patient close into occlusion. Allow the acrylic to set per the manufacturer’s instructions. Remove the provisional. Fill in any voids. It may be necessary to remove the PreFormance Posts and place those into the provisional to fill marginal voids. Remove any excess acrylic and polish. Place temporary cement into the provisional, seat it on the abutments and have the patient close into occlusion. Remove any excess cement from around the margin areas. Allow the cement to set per the manufacturer’s instructions. If a flap procedure was used during surgery, suture the tissue around the PreFormance Posts and the provisional. |
