Evaluation of the health of the peri-implant tissues around immediately placed dental implants in aggressive periodontitis patients versus periodontally healthy individuals in the maxillary esthetic zone: Controlled clinical trial

Aim To evaluate the health condition of the immediately placed dental implants in aggressive periodontitis patients compared to periodontally healthy individuals after 12 months of follow up. Materials and methods Following atraumatic tooth extraction, 70 implants were placed in two study groups: Thirty-five implants replaced hopeless teeth in aggressive periodontitis patients (test group) and thirty-five implants replaced periodontally healthy unrestrorable teeth (control group).  Results After 12 months, there were no dropouts in both groups. The criteria of the health scale showed 97.17% success in the test group versus 100% in the control group. Due to peri-implant mucosistis, only 2.85% implants in the test group showed satisfactory survival rate. It was also found that 20% of the inserted implants in both groups were covered with bone during the second stage surgery. Lack of pain, mobility, exudate and suppuration with no incidence of peri-implant diseases were clearly detected in both groups indicating the success rate. There was no statistical significant difference between the results in both groups. Conclusions  The current study highlights that immediate placement did not affect health and survival of the implants in aggressive periodontitis patients. Nearly equal results were reported between periodontally healthy and periodontally affected patients. Long- term follow up studies are recommended to examine the failure rate that could not be reported in the current short-term study.
