Abstract
The purpose of this study was comparison of clinical and radiographic outcomes of immediate post-extraction implants with or without the use of pure platelet-rich plasma (P-PRP) in the short- and medium-term follow-up. A retrospective analysis was performed to assess soft tissue healing, implant and prosthesis survival, marginal bone level changes and biological complications. A total of 109 partially edentulous patients with 126 implants were included in this analysis. At 4-5years after loading, cumulative survival rate in test group was 97.4% and in control group was 97.8%, with no significant differences. After 5years of function, marginal bone loss (MBL) in test group was 0.8±0.35 and 1.02±0.27mm for immediate and delayed loading, respectively, and in control group was 0.6±0.16 and 0.8±0.89mm for immediate and delayed loading, respectively. No significant differences in MBL were observed intragroups and intergroups at any time point considered. Soft tissue healing score was significantly higher in test group compared to the control at 3 and 7days after surgery, with significant differences. P-PRP implant group showed a better soft tissue management and wound healing in the first 7days after surgery compared to non-P-PRP implant group. In the medium-term follow-up, comparable clinical and radiographic outcomes were noticed between two groups.
