A few years ago, I had an implant, and less than a month later, it fell out. It cost $1000 then. I went after a consultation to a good dentist in Moscow, they rolled out such a list of conditions for good survival ..... They didn't tell me anything about it, or rather: "Today you don't need the sun, and don't lift anything heavy", that's it! The doctor caught the silence after that! Our ex. But, I returned the money on my next visit!!! After all, it's strictly there if I complained to the ministry. And the center itself was super, starting with blood collection, etc.
