An acquaintance spent a lot of time and effort to find a clinic in Moscow where All-on-6 implantation would be performed with high quality. So now, based on her experience, I can tell you that it makes the best sense to go to this site - https://maki-clinic.ru/stomatologiya/all-on-6-/ ! You won't find anything better.
I'm glad your friend found a good clinic for All on 6 implantation. It's a big decision! While this isn't something I need right now, I'll definitely keep the Maki Clinic website bookmarked in case anyone I know asks. Thanks for sharing!
