Rescuing “hopeless” avulsed teeth using autologous platelet-rich fibrin following delayed reimplantation: Two case reports

Figure 3 Periapical radiograph and cone beam computed tomography images of Case 1 at the first visit. A: The periodontal membrane space was widened in tooth 11, the alveolar socket of tooth 21 was empty, and no high-density foreign bodies were observed; B: Cone-beam computed tomography images showed that tooth 21 had been completely replanted, and the lip side of the alveolar bone wall of teeth 11 and 21 was fractured.
