Does not know how to do impression of front tooth, an hour and a half trying to place the bad mold he made and clicked the implant pin 8 times to remove then gave up. A nightmare, does not understand complaints, suddenly his accent gets thicker. I had to pay an expert to do a digital to create a correct crown. A nightmare that lasted a year. Can get by with an average teeth cleaning if you can tolerate rapid non stop talking. Now adays dentist can take a crash course and do implants... find a proven skilled specialist in the area.
