Title Periodontal Disease May Be A Predictor For Peri-Implantitis
Clinical Question In patients seeking dental implant therapy, does a history of periodontal disease affect the likelihood of developing peri-implantitis, and thus, the success of implant therapy as compared to healthy individuals?
Clinical Bottom Line Patients with a history of periodontal disease appear to be at greater risk for peri-implantitis and have lower implant survival rates. (See Comments on the CAT below)

#1) 20337668Roccuzzo/2010112 patients referred for dental implant placement. Grouped and treated according to periodontal statusProspective cohort study
Key resultsWith regards to bone loss of greater than or equal to 3 mm, the healthy group showed the least with 4.7%, followed by the moderately periodontally compromised with 11.2%, and then the severely periodontally compromised with 15.1%. With regards to Implant survival rate, the healthy group had 96.6%, followed by the moderately periodontally compromised with 92.8%, and the severely periodontally compromised with 90%. There was a statistically significant difference in survival rate between the healthy and severely compromised group. It was also found that there was a statistically significant difference in follow through with ideal supporting periodontal therapy between the healthy and severely compromised groups. With regards to both differences, the compromised patients showed lower survival rates and were less compliant with supportive therapy.

Comments on
The Evidence
Previous systematic reviews presented uncertain conclusions due to the inconsistencies in previous studies. Most reviewers emphasized the need for long-term data on "well-defined populations" with well-defined parameters. This study is relatively current and makes a noticeable effort to define and control for the myriad of confounding patient variables. While the study needs more refining, the authors make an attempt to improve upon previous studies on this topic.
Applicability The demographics of this study presented a relatively wide range of individuals with varied oral conditions. This study provides evidence for information one may provide to a patient regarding implant failure and the importance of supportive periodontal therapy.
