Effect of platelet-derived bone enhancers used as adjuncts to deproteinized bovine bone matrix in maxillary sinus floor elevation: a systematic review and meta-analysis
Abstract Background The success of dental implant restoration is significantly influenced by the volume and density of alveolar bone in the surgical area. Maxillary sinus floor elevation (MSFE) surgery is a reliable method to increase residual bone height (RBH) before implantation. This study aimed...

| description | Abstract Background The success of dental implant restoration is significantly influenced by the volume and density of alveolar bone in the surgical area. Maxillary sinus floor elevation (MSFE) surgery is a reliable method to increase residual bone height (RBH) before implantation. This study aimed to evaluate the impact of platelet-derived bone enhancers, namely platelet-rich plasma (PRP), platelet-rich fibrin (PRF) and platelet-rich growth factor (PRGF), when used as adjuncts to deproteinized bovine bone matrix (DBBM) in MSFE on bone neoformation, implant stability, and implant survival. Methods A systematic review and meta-analysis were conducted following the PRISMA guideline. Electronic databases, including PubMed, Embase, CENTRAL, Web of Science, Scopus, and Google Scholar, were searched up to February 2025. Randomized controlled trials (RCTs), and case-control studies assessing the effect of PRP/PRF/PRGF as an adjuvant to DBBM in MSFE were included. Mean difference (MD) or risk ratio (RR) was selected as the effect size to perform the meta analysis. Results Sixteen studies met the inclusion criteria, involving 372 patients and 455 surgical procedures. The meta-analysis revealed a significant enhancement of bone neoformation (MD = 5.92, 95%CI: 2.17 ~ 9.67, p = 0.002) and reduced residual graft volume (MD = -1.93, 95%CI: -2.25 ~ -1.61, p < 0.001) when PRP/PRF/PRGF was added to DBBM. However, there was no significant difference in graft resorption rate, percentage of fibrous tissue, immediate implant stability, and implant survival rate, between the two groups. Subgroup analyses showed that PRF subgroup, and subgroups with 4 m or 6 m healing intervals and with DBBM particles of 0.25-1 mm are related to significantly enhanced bone neoformation; all subgroups except for the PRP subgroup are related to significantly decreased residual graft. Conclusions The addition of PRF or PRGF to DBBM in the first stage of MSFE significantly enhances new bone formation and reduces residual graft volume, providing a more reliable alveolar bone matrix for subsequent implant placement. No evidence support the application of PRP as an effective enhancer to DBBM in MSFE procedure. In addition, PRP/PRF/PRGF does not significantly affect the immediate stability or survival of implants in the second stage. |
