Study explores regenerative approach to combat peri-implantitis

Peri-implantitis is one of the most hotly debated topics in the field, and there is currently no consensus about which approach should be used to treat the disease. A recent report, however, has shown promising results following the use of leucocyte- and platelet-rich fibrin (L-PRF).
The report, written by researchers at the University of Coimbra in Portugal, presents two clinical cases where L-PRF was been used to treat peri-implantitis. Studies have associated the use of L-PRF with a number of promising results, including improved/higher rates of bone regeneration and lower levels of postoperative pain. There is also limited evidence of its use for treating peri-implantitis.
The report looked at two case studies. Both patients were non-smoking males who showed no signs of periodontitis. The first patient had one implant which had been functional for seven years and the second patient had two with four years of function. There were three peri-implant lesions between the two patients.
Initial radiographs were taken before surgery and showed bone loss in both patients. During surgery, implant surfaces were decontaminated with air-flow glycine and saline powder. Peri-implant defects were then filled with compacted L-PRF membranes.
In both cases there was no immediate post-surgical swelling or pain. Patients were evaluated at regular intervals over the next 180 days. After six months the peri-implant lesions were resolved in both cases. There was a probing depth reduction in both patients following surgery, although no clear peri-implant bone fill was evident. The authors conclude by noting that there is a limited body of evidence for this treatment method and more robust controlled trials are necessary.
This study was presented as an e-poster at the 2017 EAO Congress.
