BUCCHI, Cristina; FUENTES, Franco; CANTIN, Mario  e  FUENTES, Ramón. Platelet-Rich Plasma and its Use with Dental Implants: A Retrospective Cohort Study. Int. J. Odontostomat. [online]. 2015, vol.9, n.1, pp.13-18. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2015000100002.

The objective of this study was to compare the failure rates of dental implants placed with and without Platelet-rich plasma (PRP). The study involved studying the dental records of 90 patients who had received a total of 297 implants. Of the total, 145 implants had been placed with PRP, and 152 without PRP. The overall failure rate was low (4.04%). The failure rate was lower in patients who had received PRP (2.1%) than in those who had not received PRP (5.9%). This difference is not statistically significant (p= 0.09). The reduction of the absolute risk of implant failure when PRP was used was 0.038. The relative risk, when comparing the use and the non-use of PRP, was 0.36. The reduction of relative risk was 64%. The number needed to treat was 26.3. It appears that the use of PRP may be slightly beneficial because, in clinical terms, it reduces the failure rate.
