Thus, osteosynthesis procedures are afflicted with increased failure rates. To improve osseointegration bone morphogenetic protein\u20102 (BMP\u20102) immobilized on nanocrystalline diamond (NCD)\u2013coated implant surfaces might be 1 solution.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>By 4 weeks after irradiation of pig's mandible with a dose of 60 Gy a fracture was accomplished. Osteosynthesis was performed either with titanium osteosynthesis screws or NCD\u2010coated screws with immobilized BMP\u20102. Nonirradiated animals served as control. After 1, 2, 4, and 8 weeks screws were evaluated histologically.

Consequently, immobilized BMP\u20102 resulted in an initial increased bone contact ratio (<jats:italic>p<\/jats:italic> = .014) but demonstrated no sustainable effect compared with osseointegration in nonirradiated bone (<jats:italic>p<\/jats:italic> = .08).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Immobilized BMP\u20102 demonstrates an osteoinductive effect in irradiated bone.
