Various instruments have been developed for collecting bone debris during intraoral autogenous bone graft procedures in implant surgery. The aim of this study was to quantitatively determine the degree of contamination in bone debris collected by different devices.
Twelve patients underwent autogenous bone collection using a bone chisel, bone scraper, trephine drill, and bone filter during bone augmentation surgery as a part of implant therapy, and the total bacterial count in bone debris collected by each was determined.
Following anaerobic incubation, bacterial colony formation was found in all of the samples. The mean colony forming units (CFU)/g in samples collected by the trephine drill was found to be significantly lower than that of samples obtained with the other devices, while those values for samples collected by the bone scraper and bone filter was significantly higher as compared to the bone chisel and trephine drill.
The bacterial levels may still carry the infection risk. Thus prophylactic antibiotic therapy maybe indicated when using bone particles for intraoral augmentation procedures.
在种植手术的自体骨移植过程中，已经开发出各种用于收集骨屑的器械。本研究的目的是定量确定不同器械收集的骨屑的污染程度。
12 名患者在接受种植治疗的骨增量手术中分别使用骨凿、骨刮匙、环钻和骨滤器进行自体骨采集，并测定采集的骨屑中的总细菌数。
所有样本经厌氧孵育后均有细菌菌落形成。与其他器械相比，环钻采集的样本中的平均菌落形成单位（CFU）/g 明显较低，而骨刮匙和骨滤器采集的样本中的值明显高于骨凿和环钻。
细菌水平仍可能存在感染风险。因此，当使用骨颗粒进行口腔内增强程序时，可能需要预防性抗生素治疗。
