| 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. |

| 21635280 | Levin/2011 | | Retrospective review of cases | | Key results | Overall, 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. | | 18433385 | Ong/2008 | | Systematic Review | | Key results | Implant 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. |
