Autogenous bone is routinely used for regeneration of osseous defects around teeth and implants, and different instruments are available for bone harvesting.
The purpose of this study was to describe the morphology of bone particles after harvesting with 4 different instruments.
Bone particles were harvested from fresh cow ribs with 2 different types of back action chisels, a safescraper and a sonic device. The samples were examined morphologically using light microscopy and scanning electron microscopy.
The bone particles after the back action chisel I had an appearance similar to "pencil shavings." With the back action chisel II, they were like thin paper with an "accordion bellows" appearance. After removal with the safescraper, they had an irregular shape (with an irregular surface) resembling "crushed stone." Finally, the appearance of the bone particles obtained with the sonic device was homogenous, condensed and continuous, and had a "seaweed" appearance.
Harvesting of bone particles with 4 different devices produce distinctly difference sizes and shapes, which may influence the results of grafting procedures.
自体骨被常规用于牙齿和种植体周围骨缺损的再生，并且有不同的器械可用于骨采集。
本研究的目的是描述 4 种不同器械采集的骨颗粒的形态。
使用 2 种不同类型的反向骨凿、安全刮匙和超声骨刀从新鲜牛肋骨中采集骨颗粒。使用光学显微镜和扫描电子显微镜对样本进行形态学检查。
反向骨凿 I 采集的骨颗粒外观类似“铅笔屑”。使用反向骨凿 II 采集的骨颗粒则像薄纸一样，呈“手风琴风箱”样外观。使用安全刮匙去除后，其形状不规则（表面不规则），类似“碎石”。最后，使用超声骨刀采集的骨颗粒外观均匀、致密且连续，呈“海藻”样外观。
使用 4 种不同器械采集的骨颗粒大小和形状明显不同，这可能会影响移植手术的结果。
