本报告评估了从下颌骨中取出的3个钛种植体界面的骨-种植体接触（BIC）和螺纹间骨密度（BD），该下颌骨在种植体植入前用血管化骨皮肩胛骨移植物重建并采用多向牵张成骨进行翻修。对于植入物中分别翻修0次、1次和2次牵拉的植入物，BIC和BD分别为86.9%和92.8%、67.3%和80.6%以及61.3%和77.1%。3种种植体的平均BIC和BD率分别为73.9%和84.7%。目前的评估表明，即使在牵引成骨翻修后，血管化肩胛骨移植物中的植入物也有足够的骨整合。
This report assessed the bone-implant contact (BIC) and interthread bone density (BD) of 3 titanium implant interfaces retrieved from a mandible that was reconstructed with a vascularized osteocutaneous scapular graft and revised with multidirectional distraction osteogenesis before implant placement. The BICs and BDs were 86.9% and 92.8%, 67.3% and 80.6%, and 61.3% and 77.1%, respectively, for each of the implants in the graft that were revised 0 times, 1 time, and 2 times with distractions, respectively. The average rates of the BIC and BD of these 3 implants were 73.9% and 84.7%, respectively. The present assessment indicates that there was sufficient osseointegration of the implants in the vascularized scapular bone graft even after revision with distraction osteogenesis.
