Long-Term Outcomes of Implant Treatment in Patients with a History of Moderate Periodontitis

The aim of this study was to evaluate the long-term outcome of implant treatment in patients with previous tooth loss due to a history of moderate periodontitis.

The study included 82 patients with partially edentulous and with a history of moderate periodontitis using 234 dental implants over the period from 2011 to 2021. At the baseline and at 3-month intervals, bleeding on probing (BOP), probing depth (PD) and marginal bone loss (MBL) were recorded. All patients prior implant surgery periodontal therapy were treated, which included the following: supragingival and subgingival scaling and root debridement were performed with an ultrasonic device, magnetic laser irradiation and local use of antibacterial agents.

Implant surgery was performed 3 months after periodontal therapy, when PPD < 4 mm and BOP < 10%, with stable clinical index. After 12 months in patients mean MBL 0.76 ± 0.6 mm, after 5 years MBL was 1.34 ± 0.25 mm (P > 05) and after 10 years MBL was 1.56 ± 0.28 mm (P > 05). Survival rate of implants 5 years after was 96.4%; implants 10 years after were 93.6%.

This study confirmed that implant therapy can be successfully used in patients diagnosed with moderate periodontitis who have received individualization supportive periodontal therapy and regular periodontal maintenance.
