It would help a lot if you could put a picture of the implant for us to see. Without a picture, all I can tell you is that corevent implants had several internal connections, including one that was not threaded, but was cemented instead. The only company that carries the prosthetic parts for the old corevent implants is Zimmer dental. You also have not told us whether the implant crown is cemented or screw retained. If the crown is cemented, your best bet is to take an alginate of it prior to removing it, and then remove it by cutting a groove across the middle of it, prying the halves apart with a small screwdriver to break the cement bond and make it easy to remove. Then reprepare the abutment and take an abutment level impression for the new crown. Then use the preop alginate to fabricate a temporary crown. You can also take an implant level impression, but that would require you to have identified the implant previously in order to have the impression coping ready, and also you would need to remove the existing abutment. For the easy fix, if possible, go with the abutment level impression.

I agree with Carlos an abutment impression is the way to go especially, and if it is a cemented abutment it is the only way to go. Handle it just like a regular crown prep and impression. All should go well.
