Immediate implant and socket preservation using sticky bone and leukocyte-platelet-rich fibrin in the anterior maxilla: A 3-year case report.

Introduction: Immediate implant in the esthetic area is a challenging procedure. Chronic infection often contributes to extensive bone loss and acute infection often precludes a safe, clean surgery. However, it is quite common to come across failing teeth in the esthetic area, where the patient often demands a faster rehabilitation.
Case Presentation: In this clinical case, a fractured upper central incisor was replaced by an immediate implant, and the perimetrical area was filled with heterologous bone blended with patient-derived leukocyte- and platelet-rich fibrin (L-PRF) in the form of sticky bone. A Maryland bridge was bonded to the adjacent teeth with the intent to guarantee minimum esthetic to the patient. After 5 months, the implant was connected to a definitive abutment and crown. The facial and interdental soft tissue was maintained with appreciable success after 2 years. The pre-treatment and 2-year- post-treatment computed tomography scans revealed marginal bone preservation.
Conclusion: The use of sticky bone and L-PRF in immediate implant sites helps prevent hard and soft-tissue collapse and may favor faster and sounder healing.
Key Points: Why is this case new information? It provides support to the efficacy of immediate implant placement with simultaneous use of L-PRF. What are the keys to successful management of this case? Having L-PRF supporting wound healing. What are the primary limitations to success in this case? Having sufficient bone apical to the existing socket and at adjacent teeth.
