Title Patients With Periodontitis Are More Likely To Have Implant Failure
Clinical Question Are patients with periodontitis more likely to have dental implant failure than patients who do not have periodontitis?
Clinical Bottom Line Patients with significant periodontitis have a higher dental implant failure rate than those with a healthy periodontium.

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 21635280Levin/2011Retrospective review of cases
Key resultsOverall, 97% of implants survived in patients without periodontitis or with moderate chronic periodontitis; 95% survived in patients with severe chronic periodontitis. Periodontitis was a significant (p<.01) risk factor for implant failure after, but not before, 50 months.
#2) 18433385Ong/2008Systematic Review
Key resultsImplant survival ranged from 100% in both periodontitis and non- periodontitis patients at 4 years to 79% in periodontitis and 92% in non-periodontitis patients at 10+ years

Comments on
The Evidence
Levin: Patients were followed for a mean of 54 months (+/- 36 months) post implant placement Ong: The 4 selected papers that reported on implant failure included 1 cohort study and 3 case series, with patients followed 4-10 years after implant placement. The reviewed studies were heterogeneous both in design and in reporting of results, preventing the quantification of risk added, if any, by periodontitis.
Applicability Patients with severe chronic periodontitis will have the least successful survival rate of implants. According to Levin, "after 50 months hazard for implant failure is eight times greater for severe periodontitis patients." Patients who have been diagnosed with periodontal disease should be aware that there is a probability of implant failures and that they should first treat periodontal disease.
