This is my negative review: 1/ My implant crown lasted less than 10 years 2/ At the bottom, the crown has a tiny neck call the abutment. It is less than 1/8 of an inch in diameter, it is not made to last forever If your bite is not even, it can fracture the abutment, you will then need a new crown. 3/ After the first 18 month of using my implant crown, Dr Balogh recommended a bite adjustment on a adjacent tooth, even though my bite was even. After this adjustment, there was a heavier contact on my implant crown. Later on, this implant crown became loose, I can actually twist it back and forth. Dr.Balogh said if it gets worst he will adjust the bite. However, the abutment eventually broke off . Had the bite adjustment not been done, this may never have happen.
