Alveolar ridge augmentation of the maxilla with wound dehiscence. A The intraoperative baseline showed an extended horizontal alveolar ridge atrophy. An allogeneic cortical bone plate was fixed laterally to the defect by two adjusting screws. B The space between the allogeneic cortical bone plate and the local alveolar ridge bone was filled with spongious allogeneic granules and the area was covered by a porcine pericardial matrix. C After a few weeks, a dehiscence defect with an exposure of the allogeneic CP was found. D Surgical re-evaluation demonstrated a plate fracture along the screw holes (white arrows). E CBCT scan demonstrated a sufficient bone volume for implant placement. F X-ray demonstrating the inserted implants
