Bone augmentation and biopsy: clinical report

A mixture of demineralized freeze-dried cortical bone and beta-tricalcium phosphate covered by titanium-reinforced expanded polytetrafluoroethylene membranes was used for bone augmentation in an accident case in which a young female patient suffered anterior maxillary damage. Hydroxyapatite-coated implants were placed in the newly formed bone-like material before prosthodontic reconstruction. A biopsy suggests the bone-like material was essentially normal lamellar and woven bone.
