The use of intraorally harvested autogenous block grafts for vertical alveolar ridge augmentation: a human study.

摘要: This study presents a clinical, radiographic, laboratory, and histologic/histomorphometric analysis of the use mandibular block autografts for vertical alveolar ridge augmentation. Twelve patients were included in study. The autogenous fixated at recipient sites with screws, mixture bone marrow inorganic bovine mineral (Bio-Oss) was used periphery. At re-entry surgery, all grafts appeared well incorporated sites. Radiographic measurements revealed an average 5.75 +/- 1.29 mm augmentation 1 month after surgery 4.75 4 to 6 months surgery. indicated 17.4% resorption. Laboratory volumetric 0.84 0.34 mL 0.71 0.28 postoperatively. resorption rate according laboratory 15.5%. Linear 5.92 1.38 postoperatively 4.08 1.01 Histologic evaluation signs active remodeling activity 10 12 specimens. In one case graft became exposed infected, another autograft dislodged during implant placement Histomorphometric peripheral particulate present 33.99% 8.82% surface, while 42.43% 11.06% area occupied by fibrous tissue 23.89% 9.12% made up residual Bio-Oss particles. Residual particles tight contact newly formed along 58.57% 15.22% their perimeter.
