Then sterilize ready for the patient. Now here's the part where some of the photos came out completely overexposed (a fault with the camera, not the settings, but I found that out too late!). Here we are looking end-on at the temporary crown. We take the temporary crown out and here is the sulcus. The white particles are some of the OsteoGen graft that hasn't been incorporated. I just blast that away with some air and water spray. Look at the shape of the sulcus, though. No normal sulcus former is going to fit in there whilst I'm customizing the impression post. Fortunately, I've got that sulcus former I customized earlier. Now that fits just fine. Take a laboratory implant analog, the temporary crown you've just removed and that impression post you sandblasted earlier. Screw the temporary crown into the implant analog. Mix up some impression putty and then squash it around the implant analog and temporary crown. You want all the subgingival part of the temporary crown to be covered in the putty. Unscrew the temporary crown, leaving the implant analog behind in the putty. See how I've made a groove in the putty at the front of the crown? Screw that sandblasted impression post into the implant analog, lining up the post with that groove in the putty. Use some flowable composite to fill in the gap. It should stick to the sandblasted surface of the impression post. Unscrew the impression post from the implant analog and remove the impression post from the putty. It might not look like much here, but you've perfectly captured the subgingival shape of the temporary crown. Making that customized impression post has taken some time. Thank goodness I had something in the implant to stop all that lovely soft tissue from collapsing in that time. Remove the customized sulcus former and screw in the customized impression post.
