Immediate implant placement in extraction socket with previous periapical infection

Introduction: Immediate post-extraction implant placement is a well-accepted protocol due to the preservation of aesthetics, shorter total treatment time, maintenance of socket walls, and reduced surgical time. Despite all these advantages, there is a risk of microbial intervention in cases with periapical lesions which can delay the process of osseointegration. Aim: To evaluate the successes of the immediate implant placement in areas exhibiting periapical lesions, gaining aesthetics and function by establishing a successful protocol for safe implant embedding. Surgical intervention and bone grafting were performed in advance of tooth extraction in order to resolve the infection and develop the site for immediate implantation, helping ensure the bone volume needed for high primary stability. The reported case has clinically demonstrated that interim endodontic and periapical site preparation, when performed correctly can eliminate the hopeless tooth infection, regenerate bone, and facilitate satisfactory immediate implant placement. Conclusion: This study is proof of the principle that sockets can heal naturally with immediately placed implants in infected sites and tissue shrinkage can be reduced by utilizing the least invasive surgical and prosthetic protocol
