In a 2024 meta-analysis, about 92% of implants followed in prospective studies were still in place after 20 years.
Smokers had higher odds of failure in a meta-analysis (odds ratio 2.402).
Fees depend on the parts, any grafting and the number of visits, so a single average figure would mislead more than it helps.
A pooled estimate put implant loss after a sinus lift at 0.43% a year.
How we writeEditorial policy
Each guide starts from published research: systematic reviews and meta-analyses where they exist, then clinical trials, then patient information from professional bodies such as the American Dental Association. Every figure on a page names the study it comes from.
Numbers are copied from the source, not rounded into new claims, and kept with their conditions: follow-up period, patient group and confidence interval. A result that was not statistically significant is described that way.
The guides explain published clinical practice. They are not a diagnosis or a treatment plan, and they do not replace an examination by a dentist.
Guides are written by the Implants Dental editorial team. We do not list reviewers we do not have. When a source is updated or withdrawn, the guide that cites it is revised.
