The temporary abutment is a VITA CAD and this is what Straumann has recommended for this case. I have made a putty matrix using the original fractured tooth and crown (see last photograph). I am an associate and do not have access to making a suckdown. I also don't want to put any more fees onto the patient. I'm having the lab fabricate one for me. She has already paid for a fl ipper. I am not sure why a gingival replica was not returned with the poured-up models from the lab (they always do this for me). The PVS impression was not returned with the case. Is it destroyed when poured with open-tray impression coping? Undercuts! Please see photographs of the model. I will be using a bis-acryl temporary material and my concern is locking the provisional into undercuts as setting occurs, and a screw access hole covered. I remember a technique outlined by Brad Blair in a thread where he used petroleum jelly on the abutment so that the provisional material could be removed during setting (solid phase) without having to worry about access to the screw hole. The other option would be to wax the undercuts. Thoughts? I welcome comments on my reduction of the temporary abutment as well. There are a few other things I wanted to discuss with this case, but lunch is over and a crown preparation awaits. Thank you very much! ■ JAN 20 2015 drsaul Member Since: 10/12/12 Post: 2 of 24 Easy. Use your putty pre-op matrix. Put some Teflon tape in the screw hole of the abutment. Make temporary on abutment as you would for crown and bridge. Your abutment will act as the gingival former to train the tissue. You will screw the temporary abutment into place on implant. Place Teflon in screw hole. Cement temporary abutment. You can use permanent cement. If you need to retrieve, just drill through the temporary until you get to Teflon tape. Unscrew abutment. If you need to reseat abutment, just screw it down, and repair access with flowable. ■ JAN 20 2015 Brad Blair Member Since: 01/11/08 Post: 3 of 24 36 I didn't quite follow the whole discussion, but what you have so far looks fantastic. Since you have models, I would complete the thing indirectly, as you have here. The problem with screw-retained in the anterior is that the screw hole seems to exit in the more inconvenient place. So make this one a two-piece deal. Abutment with supragingival margins, then temp crown cemented on top of that, just like a tooth.
