Please note! It is very dangerous to be treated at Katan Dent dentistry on Karl Liebknecht 15, because they do not give you any checks and documents that you were treated by them, and in case of problems they send you away! This is what the owner of the clinic, Evgeny Alexandrovich Katan, does! I faced the problem of an irresponsible attitude when channels were made for me in 5 minutes and the material was removed from the top of the root by 35-40 mm, and when there were natural hellish pains, they simply sent and closed the door to such an abuse of the body! Now I'm going to have a complicated operation, resection of the tip of the root, at my own expense. It wasn't just me who was so unlucky, one girl complained that the implants were put in such a way that they flew out after half a year and no one returned the money for the installation. Another girl had an implant placed in such a way that it fell out into the maxillary cavity and had to undergo a complex endoscopic operation at her own expense to remove this implant from the maxillary sinus through the nose under general anesthesia. And how many more victims who did not share information about their sad experience!
