How Long Do Dental Implants LastOne of the benefits of dental implants is that they are long-lasting restorations, but just how long do they last? We often say that dental implants are a lifetime restoration because they have the ability to last for a lifetime. The first four dental implants placed by Dr. Per-Ingvar Brånemark were in place when their owner died—four decades after the procedure. We can’t guarantee that your implants will last a lifetime, but our experience—and clinical studies—suggests that they will last a long time.

Clinical Data on Implant Survival Rates

Most of the studies looking at dental implant survival rates are relatively short, 5-8 years, but there are a few good studies that go out to 20 years. We will summarize these studies briefly below:

Survival Rate Study Length Number of Implants Authors Date
91% 20 Years 69 Lekholm U, Gröndahl K, Jemt T 2006
99% 20 Years 123† Astrand P, et al. 2008
89.5% 20 Years 95 Chappuis V, et al. 2013
93.3% 20 Years‡ 12,737 Krebs M, et al. 2015

The original population of this study was 48 individuals, but 19 died before the follow-up period, so the data reflects only implants in the remaining 29 individuals.

Although the study is 20 years long, the survival rate is calculated on the basis of 17 years.

Although many of these studies are relatively small, the Krebs study makes up for them, using comprehensive data from an implant manufacturer to give a comprehensive picture of the overall implant survival rate for 20 years.

Most dental implant failures occurring within the first few years. In fact, in the Krebs study, most of the implant failures happened during the first six months after placement, with a very small number occurring after five years. With dental implant failures becoming less frequent after the first year, it seems likely that most, if not all, of the dental implants still in place at 20 years will last at least another decade and quite likely two.

Avoiding Early Implant Failure

Since most dental implant failures occur in the first year, it’s vital that you avoid these risks of early failure. That means understanding why dental implants tend to fail early. The two primary causes of early failure are peri-implantitis and failed osseointegration, which together accounted for about two-thirds of all dental implant failures.

Peri-implantitis is a form of gum disease that attacks dental implants. It’s an infection of the dental implant that damages the bone around the implant, causing the implant to loosen, and, eventually, fail.

Osseointegration is when the bone grows around and secures the dental implant. Failure of osseointegration can be related to your bone quality, smoking, whether bone grafting was used, and the surgical technique of your implant dentist.

Based on these two main factors in dental implant failure, it’s crucial that you commit to taking care of your dental implants and make a careful choice about your implant dentist.

At Rice Dentistry, we work with a periodontist, a specialist in the gums and bone surrounding teeth, to help ensure that the placement of the dental implant and management of the tissue around the dental implant are both conducted properly.
