Objectives: To evaluate the clinical effects and radiographically analyze the effectiveness of fibrin-rich plasma (FRP) in post-extraction bone preservation in a resource-limited community, considering its potential to mitigate complications and facilitate future rehabilitation. Materials and Methods: A case series was conducted in San Vicente Chicoloapan, State of Mexico, analyzing four patients treated with FRP after dental extractions. The protocol included centrifugation of blood at 1300 rpm for 8 minutes to obtain FRP, which was placed in the alveolus after extraction. Clinical and radiographic follow-up was performed using Handy Dentist software to assess healing, changes in bone height, and density. Results: In all four cases, complete gingival healing was achieved without complications. The case with the longest follow-up showed 97.8% bone preservation at seven months. Radiograph...
