Autologous platelet concentrate for post-extraction socket healing : a systematic review

Autologous platelet concentrates are claimed to enhance hard and soft tissue healing due to the considerable amount of growth factors that are released after application in the surgical site. However, their actual efficacy for improving tissue healing and regeneration in oral surgery applications is controversial. Tooth extraction socket healing represents a proper model to study the effect of autologous platelet-enriched preparations due to the concomitant occurrence of different processes of both hard and soft tissue healing.
