Horizontal guided bone regeneration in the posterior maxilla using recombinant human platelet-derived growth factor: a case report.

This clinical case report describes and demonstrates the successful use of purified recombinant human platelet-derived growth factor in conjunction with autogenous bone, an organic bovine bone-derived mineral, and a barrier membrane to reconstruct severe alveolar bone defects. Significant horizontal bone regeneration was achieved in the posterior maxillary region. Three implants were placed into the newly formed ridge and demonstrated stable crestal bone after 36 months of loading.
