Efficacy of Autogenous Platelet-Rich Fibrin Vs Slowly Resorbable Collagen Membrane With Immediate Implants in the Esthetic Zone

Oral rehabilitation with dental implants has been a successful treatment option for many years. Different implant protocols were developed aiming for safe placement and loading, and faster uncomplicated outcomes.¹  Earlier protocols suggested a period of 24–48 weeks for complete healing before the placement of an implant.²  Recently, modified protocols suggest immediate implant placement after tooth extraction. Immediate implant placement minimizes the alveolar bone resorption and lowers the chance of fenestration and dehiscence. Additionally, it reduces the number of surgical sessions and provides better esthetics.³  However, these advantages might be accompanied by minor drawbacks, such as the presence of deficient apical bone and unfavorable postextraction configuration, which might complicate the implant placement and stability. In addition, tension-free suturing might not be feasible when implant placement is accompanied by necessary bone grafting. Furthermore, bur chatter at the osteotomy site might further complicate the situation.⁴  Therefore, careful patient evaluation...
