Is Autologous Sticky Bone Better Than a Simple Mixture of Autologous PRF and Bioactive Glass in the Regeneration of Human Periodontal Intrabony Defects? An Extensive Clinical and CBCT Study

Abstract

Periodontal intrabony defects (IBDs) are commonly encountered in dental practice and are usually treated by open flap debridement (OFD) with or without bone grafts and/or guided tissue regeneration (GTR), platelet-rich fibrin (PRF), or other additives. A difficulty with these approaches is maintaining the space for bone growth at the determined location. In this report, autologous sticky bone (ASB) was used and compared to a simple mixture of PRF and bone graft (PRF-BG) using the identical graft material—bioactive glass morsels—to assess its regenerative potential in IBDs, as sticky bone is known to maintain the space, according to previous research. A total of 21 IBDs were treated by OFD, PRF-BG mixture, or ASB. Regenerative assessment was clinically and radiographically performed by CBCT at 1 year. All the treatment modalities (OFD, PRF-BG, and ASB) showed statistically significant improvements clinically and radiographically at 1 year in terms of probing pocket depth reduction (PPDR), clinical attachment level gain (CALG), CBCT defect fill (CBCT-DF), and CBCT defect resolution (CBCT-DR); P < .05. The ASB group depicted the most favorable results (P < .05) in terms of the parameters at 1 year followed by the PRF-BG group and then the OFD group. Treatment of periodontal IBDs with ASB resulted in significant improvements in clinical and CBCT parameters compared to baseline at 1 year, and intrasurgical graft handling was much better in the ASB group.
