This study was conducted to evaluate the use of plasma rich in growth factors (PRGFs) with immediate implant placement in periodontally compromised extraction sites.
Fifteen patients with chronic periodontitis were included. Each received two implants placed immediately after extraction in the anterior region of the mandible.
One of the two implants was treated with PRGFs (group I), while the other was not and served as a control (group II). Implant survival, plaque index (PI), bleeding index (BI), probing pocket depth (PPD), and marginal bone loss (MBL) were evaluated for both groups.
Complete soft tissue healing occurred in all patients and all implants were successfully osseointegrated over 12 months. At 12 months, results showed mean PPD values of 3.8 ± 0.3 mm at the control site (group II) and 3.4 ± 0.4 mm at the test site (group I);
The mean MBL values were 1.1 ± 0.1 mm at the control site and 0.6 ± 0.1 mm at the test site. There were no statistically significant differences between the test and control groups regarding PI or BI, while there were statistical differences between the test and control groups regarding PPD and MBL throughout the follow-up period.
