Influence of Platelet Concentrates on Postextraction Socket Healing: A Literature Review

Abstract

Socket healing after extraction of teeth leads to a significant decrease in residual bone in both vertical and horizontal dimensions. This dimensional loss of bone volume poses a challenge when replacing these teeth. Implant placement and grafting procedures include the use of platelet concentrates. Platelets play a role in socket healing. Autologous blood derivatives have a high concentration of platelets. Hence, they have been used to preserve and correct defects due to loss of bone volume after extraction. The use of bioactive materials started with fibrin glue and now includes two generation of platelet products comprising various subtypes. Bioactive materials such as platelet concentrates were first used to prevent and control hemorrhage in surgical procedures. The platelet concentrates are categorized based on their preparation protocols and concentration of leukocytes and platelets. This review article aims to summarize the classification, applications, efficacy, indications, and benefits of platelet concentrates.
