What is the percentage of implant failure? I have heard other people comment on implants not lasting a long time.
I probably should answer this in two parts.
The first part, the percentage of implant failure is very low, which means the success rate is very high. A success rate of 95 to 99% is seen in the literature.
The second part, which deals with the longevity of implants has more variables in it. Implants lasting twenty years are not uncommon, but an implant that has been clinically successful for many years can eventually fail if the routine conditions of good oral hygiene and regular professional care are not followed by the patient.
For the majority of cases, implants are very long lasting.
