I am inclined to agree it is a Tri-lobe just going by the mandibular implant. If it is the same surgeon, they typically use the same system, so if I was a gambling person, I would sat likely a RP Replace also. LCM
they both can be the same conical connection so zoom in on that and see if its parallel internally or not .i cant tell from this x ray if its conical it doesnt matter.have a look at the restored crown that looks like conical connection to me so compare the 2.
Active is thread design (active is very agressive). The active implant was the first Nobel design with a conical connection. Nobel then applied the conical connection to all of they're line of implants (tapered, parrallel etc).
