在种植外科的口腔内自体骨移植过程中，已经开发了各种收集骨碎屑的器械。这项研究的目的是定量确定不同装置收集的骨碎屑中的污染程度。作为种植治疗的一部分，12名患者在骨强化手术中使用骨凿、刮骨器、环钻和骨过滤器进行了自体骨收集，并测定了各自收集的骨碎片中的细菌总数。厌氧培养后，所有样品均有细菌菌落形成。环钻采集的样本的平均菌落形成单位(CFU)/g显著低于其他设备采集的样本，而刮骨器和骨过滤器收集的样本的平均集落形成单位(CFU)/g显著高于骨凿和环钻。细菌水平仍可能带有感染风险。因此，当使用骨颗粒进行口腔内隆起手术时，可能需要预防性抗生素治疗。
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.
