Comparison between the healing of autogenous and heterogenous bone grafts [experimental study]

ABSTRACT

In the present study, 12 male adult dogs were randomly divided into two groups, each consisting of six dogs. Surgical bone defect was created in the inferior border of the mandible. For the first group, the defects received rib autogenous graft, and Kiel bone was placed in the second group. Histological sections, using H and E stain, were performed after each sacrifice of the 2 animals at 6-, 12- and 24-week intervals [two specimens at each interval]. The results were successful and promising with autogenous and heterogenous grafts. However, Kiel bone had higher advantages, besides high osteogenic potential in terms of eliminating a second operation, as in autografts, as well as time saving, ready availability, with ease of the shape selection
