摘要
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.
