Intra-oral Luting of Implant Verification Jig and Pick-up Impression for Mandibular Hybrid
Label each individual GC pattern covered direct impression transfer post with it's appropriate location.
Hand tighten each post onto the appropriate implant.
Ensure the GC pattern resin is not touching when in place.
If margins are subgingival and seating verification cannot be visualized, peri-apical radiographs may be necessary to verify complete seating of the transfer posts.
Isolate the area from saliva using cotton rolls and gauze.
Brush bead the gaps between each direct transfer post with GC pattern resin.
Ensure the GC pattern resin fills the space entirely.
Allow, GC pattern resin to polymerize for 10 minutes.
Loosen impression screws and remove from the patient's mouth.
Place the verification jig on the original cast and verify passivity of fit.
If the jig seats completely and passively on the preliminary cast no verification jig pick-up impression is needed.
If the jig does not seat passively proceed with the custom tray verification jig pick-up impression.
Re-attach the verification jig to the implants in the patient's mouth and hand tighten.
Verify fit of the custom tray over the verification jig while in the mouth
Make adjustments to the tray if necessary
Apply adhesive to the inner surface of the tray.
Isolate the verification jig in the mouth from saliva.
Apply light body polyvinylsilosane around the verification jig.
Apply heavy body polyvinylsiloxane to the internal aspect of the tray simultaneously.
Insert into the patient's mouth and wipe away excess from the screw access holes. Have the pooch and smile to border mold
Leave impression material in place with patient relaxed for 5 minutes.
