Fig. 2From: Osseointegrative effect of rhBMP-2 covalently bound on a titan-plasma-spray-surface after modification with chromosulfuric acid in a large animal bone gap-healing model with the Göttingen minipigComparison of the BMP-2 group and the TPS group for osseoconduction. a Osteoid ongrowth and b bone ongrowth by group (BMP-2 vs. TPS) and postoperative duration (4, 8, and 12 weeks). For the osteoid to implant contact, expressed by the variable osteoid ongrowth, a significant difference between BMP-2 and TPS over the whole observation period was able to be shown, in favor of BMP-2. After 4 and 8 weeks, there was significantly more bone to implant contact (bone ongrowth) in the BMP-2 group with no statistically significant difference after 12 weeksBack to article page
