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

Figure 4 Periapical radiograph and cone beam computed tomography images of Case 2 at the first visit. A: The alveolar socket of tooth 22 was empty, and no high-density foreign bodies were present; B: Cone-beam computed tomography image showed that tooth 22 had been replanted completely, and no alveolar fractures were noted around the empty tooth socket; C: Cone-beam computed tomography image showed that the fracture edge of tooth 21 was approximately 3 mm above the top of the alveolar crest.
