it is called Abutment Design, if you want to do bridges as well then you also need to get the implant bar/bridge module. At this point i would simply upgrade your dongle to a complete restorative/ you get all the modules for only 700 more then your premium design seat renewal, upgrade is around 3700. If you want to just do the abutment design and implant bar/ bridge module both modules are 2500 each and yearly combined is 500. DO the math for 1500 less and 200 more a year you get all the modules, minus ortho and implant studio. you get premium design, abutment design, implant bar/bridge, removable, partial and all scan model builder. all for around 2500 a year.
