Pre-Surgical Fabrication Of Partially Edentulous Provisional Fixed Crown Or Brid
Pre-Surgical Fabrication Of Partially
Edentulous Provisional Fixed Crown Or Bridge
Fabrication Of Master Cast, Articulation And
Vacuum Formed Template
1. LABORATORY Over tightening the Analog Mounts outside of the Master Tubes may damage the Analog Mounts.
Select
the proper diameter and length Analog Mounts for each implant position
following the instructions provided by the surgical guide manufacturer.
Place the implant analogs onto the Analog Mounts, line up the hexes and
thread the thumb screws into these approximately two turns. Place the
Analog Mount/analog assemblies through the Master Tubes, engage the
rotational positioning notches and tighten the thumb screws using the
Square Driver.

2. Mark the planned implant locations on the preoperative cast and drill holes for each implant that is slightly larger in diameter than the implant analogs. Do not drill through the guide. Insert the implant analogs attached to the surgical guide into the holes and seat the guide onto the remaining teeth on the cast. Fixate the analogs in the cast using stone or pattern resin. Unscrew the thumb screws and remove these. Remove the surgical guide from the master cast. |

3. If a scanning appliance was fabricated on this cast, place it on the master cast and verify the fit and tooth position. Articulate the master cast with the opposing cast using the bite registration. |

|
4. Make a vacuum formed template over the scanning appliance or diagnostic setup on the cast. Remove the template and the scanning appliance or setup and separate those. Continue on to step 5 on the following pages for abutment selection and provisional fabrication. |
