Clinical Data on Implant Survival Rates
Most studies on dental implant survival rates are relatively short, 5-8 years, but a few good studies extend to 20 years. We will summarize these studies 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 |
| 94% | 22 Years* | 10,871 | French D, Ofec R, Levin L | 2021 |
†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 based on 17 years.
* Although the study is 22 years long, the survival rate is calculated based on 15 years.
Although many of these studies are relatively small, the Krebs and French studies make up for them, with comprehensive data that gives a complete picture of the overall implant survival rate approaching 20 years.
Most dental implant failures occur within the first few years. In the Krebs study, most implant failures happened during the first six months after placement, with a minimal number occurring after five years. With dental implant failures becoming less frequent after the first year, most, if not all, dental implants still in place at 20 years will last at least another decade and probably two.
We don’t know the point at which wear and tear will increase the implant failure rate, indicating the end of their expected lifetime. However long that is, it seems to be more than 20 years, at least.
Learning from Dental Implant Successes
The first dental implant was placed in 1965. The patient who got that first set of dental implants, Gösta Larsson, passed away in 2006, with his original implants in place more than forty years after receiving them.
The second patient to get dental implants was Sven Johansson, who got them in 1967. He had his implant-supported dentures for nearly 50 years!
Mr. Johansson had 11 dental implants used to support a permanently affixed implant-supported dental bridge made of gold and acrylic. Over the years, he needed to replace the bridge but not his implants.
What You Can Do to Make Your Dental Implants Last 50 Years or More
Getting dental implants placed is one thing, and having them last 50 years is another. There are many essential elements to making dental implants last.
- First, it’s crucial to ensure that the implants are good quality, as is the denture or other restoration that will top them. The best material for a dental implant is titanium. It’s corrosion-resistant and integrates well with the body’s hard tissues. Titanium is used for similar situations, like knee and hip replacements.
- Next, patients must have a good, long-standing relationship with their Irvine implant dentist. Dental implant care–like other oral health care–has to change as patients age to meet changing needs. It may mean more visits or changes in home care and/or diet.
- Finally, patients need to care for dental implants like natural teeth. That means practicing good oral hygiene: brushing and flossing twice a day and visiting their Irvine dental implant dentist at least twice a year.
If you want dental implants that will last 50 years–or more–you must commit to your implants, Irvine dentist, and personal care.
Avoid Early Implant Failure
Since most dental implant failures occur in the first year, you must avoid the risk of early loss. That means understanding why dental implants tend to fail early. The two primary causes of premature failure are peri-implantitis and failed osseointegration. These together account 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 it, causing it to loosen and eventually fail. This is why it’s imperative that you take care of your dental implants like you would natural teeth, or you might lose them to peri-implantitis.
- Osseointegration is when the bone grows around and secures the dental implant. Failure of osseointegration can be related to your bone quality, smoking or using other tobacco products, whether bone grafting was used, and the surgical technique of your implant dentist.
Based on these two main factors in dental implant failure, you must commit to taking care of your dental implants and make a careful choice about your implant dentist. If you have tooth extraction due to gum disease, postponing your dental implant procedure until after gum disease treatment might be worth it.
At Rice Dentistry in Irvine, 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 it is appropriately conducted.
