is actually pretty easy.
you have three steps to this process: 1. export the scanned model *. 2. export the design file for the implant abutment plus the anatomic crown or coping to be made ** . 3. place the analog with the scan body or analog using steps 1 and 2.
this is where it gets tricky.
* technically you will scan an impression, with an analog in place. this is an impression with no wax around the analog collar that you would otherwise use when sealing the analog against the flow of stone. so a relatively easy step.
after this you will need to give the scanned impression a scan body. this means you will use a custom scan body set that uses your preferred scan body overtop of the implant analog as one piece. you will do an alignment now, not based on the scan body but the implant analog. when it aligns correctly you should have a digital model complete with implant analog in the correct position.
** now, printing that or milling that is another issue. you will go through the design phase, and make a secondary design that incorporated the adjacent tooth or teeth or gum ridge into the coping or abutment. if you print the model with the hole ready for the analog you can use this incorporated design as a jig, while you inject some silicone or glue or such to hold the analog in place.
in practice i have not yet actually done this, rather i am working on the concept to make it less time constrictive. this is going to make it take all day to make the model. this is too long. i can however say that making the custom scanbodies is virtually the easiest part of it.
