Abstract

Abstract: Objective: The aim of this retrospective cohort study was to assess factors associated with peri‐implant disease in partially edentulous patients with a history of severe periodontitis or no history of periodontitis. Methods: Partially edentulous patients with a history of severe periodontitis/without history of periodontitis who received implant surgery within the past 6 to 8 years were recalled. Clinical and radiographic examinations were recorded. Periodontal probing depth, marginal bone loss (MBL) and peri‐implantitis were considered as the primary outcome and peri‐implant bleeding on probing (BOP) was considered as the secondary outcome. The following criteria were considered as the predictors, as well: history of severe periodontitis, gender, age, smoking, brushing frequency, recall interval, full‐mouth plaque score, full‐mouth bleeding score, splinted prosthesis, open/tight interproximal contact, width of keratinized mucosa, mucosal thickness, implants placed in the grafted bone and implant type. Univariate and multivariate regression analyses were utilized. Results: A total of 88 patients (186 implants) fulfilled the study. Forty‐seven patients (108 implants) had a history of severe periodontitis and 41 patients (78 implants) had no history of periodontitis. There was a higher chance of peri‐implantitis in patients with a history of severe periodontitis (OR = 11.13; p = 0.045), implants with lack of peri‐implant KM (<2 mm) and implants placed in the grafted bone (OR = 14.94, p < 0.001; OR = 4.93, p = 0.047). The risk of peri‐implant MBL ≥3 mm was higher in patients with greater FMBS (OR = 1.20; p < 0.001). The chance of peri‐implant BOP was independently higher in patients who brushed their teeth at most once per day (OR = 3.20; p = 0.04), higher FMBS (OR = 1.16; p < 0.001) and irregular recall visits (OR = 15.34; p = 0.001). Conclusions: Partially edentulous patients with the history of severe periodontitis, lack of peri‐implant KM and implants placed in bone‐grafted sites expressed higher probability of peri‐implantitis. In addition, inadequate frequency of brushing (at most once daily) and irregular recall visits were associated with greater chance of peri‐implant BOP.
