I placed an implant with buccal graft covered by non-PTFE membrane and buried it 4 months ago.
Graft thickness according to CBCT was 2.3mm.
I took another CBCT 4 months later and the graft has resorbed to 1.5mm and I can see the greyness of the fixture through the gingiva. I’m pretty sure when I expose the fixture for second stage it will expose some threads.
Should I re-graft the site with more particulate bone graft ? Will it osseointegrate against the current graft?
Thanks for your thoughts!
