Factors That Increase Implant Failure
In this study, the success rate of dental implants was high, as expected. Only 1.1% of implants failed in the follow-up period, a success rate of nearly 99%.
In looking at the failure rates, researchers only came up with two factors that affected failure rates: osteoporosis and gender.
Osteoporosis and Dental Implant Failure
The biggest impact on dental implant failure risk was osteoporosis. Patients with osteoporosis were more than 4.5 times more likely to experience dental implant failure.
Osteoporosis is a condition in which your bones lose density. Since dental implants depend on the support of your bones, having more porous bones reduces the amount of bone available to support dental implants. Although not all studies show that osteoporosis increases the failure risk for dental implants, they usually show that the condition reduces the amount of bone support for implants.
One of the advantages of the digital dental implant procedure that our Sydney implant dentists use is that it lets us assess the density of bone at your implant site or sites. We can analyze your risk and recommend strategies to maximize your chances of success.
Gender and Dental Implant Failure
In this study, men were about twice as likely to experience dental implant failure as women, after correcting for other potential factors. This isn’t the first study to show this correlation. Most large studies of dental implant survival show that women have lower failure rates than men.
Why do men have a higher implant failure rate? The explanation is likely quite simple: oral hygiene. In the US, men are less likely to brush their teeth than women. Unfortunately, the same is true in Australia. In a 2020 study published in the Australian Dental Journal, 98% of women brush with toothpaste at least once a day, compared to only 95% of men. This highlights the importance of good oral hygiene for maintaining your dental implants.
