Dan Butterman Currently, my preferred way to use an Atlantis abutment is with a cement retained crown because the workflow is so slick and seamless, but going screw retained just takes a bit more work. This is a test case on a model that I did to look at the steps for a screw retained crown. When choosing the abutment type, you select a screw retained custom base. The core file that is sent back to you will contain the screw access position and orientation in the gingival mask folder (took me a minute to find it). You just need to use form minus or circular shape tools to reduce the porcelain in the area of the screw so that when it mills you'll see the dimple of where to cut through.
