Porous Titanium Granules in comparison with Autogenous Bone Graft in Femoral Osseous Defects: A Histomorphometric Study of Bone Regeneration and Osseointegration in Rabbits

Figure 3

Comparison of defect healing and histological osseointegration in the three treatment groups (views of complete defects above and overview images of the lateral condyle below). The control group (resorbable membrane alone) showed very little new bone tissue in the marrow compartment of the defect. Bone formation was clearly stronger in the group treated with autogenous bone. Osseointegrated remnants of the graft (asterisks) were still present. In the defect filled with PTG, many titanium granules were detectable and well integrated into new bone tissue. The composite of granules and surrounding bone fills the defect to a larger extent than is the case in the other groups. Black dashed lines indicate the borders of the drill holes (microphotograph of horizontal undecalcified thin‐ground sections, Levai–Laczko stained).
