I had a historical on this from 2005…subsequent to which a Zirc was placed.
I took a look at it and knew there wasn't going to be any point in a traditional access…i.e. even if I cut a traditional access, it would be a search and try-not-to-destroy in the roots. Found four PONs. CBCT in CH to check (not shown).
So instead, I cut a wide swath through the Zirc (stepped access) and accessed each root individually…aka "dual" or "truss" access.
Pure SSW 17/V.04 shapes in all four PONs.
Amalgam crown repair.
About a 7 month followup from today.
