My front tooth collapsed. The root was removed, before that the tooth was restored. I was just in a panic. On the advice of a friend, I turned to Andrii Volodymyrovych Korniienko, the orthopedic dentist. After examination and diagnosis, he said it was better to install the pin. I was ready for anything. Andrii Volodymyrovych did everything well, the tooth didn’t not interfere, it looked great! It is very rare to find such  professional today. I hope my feedback will be useful to someone.
