The aim of this study was to find an optimal value for tightening the Smartpegs for magnetic radiofrequency analysis devices (RFAs) devices. Thirty implants were placed in 3 cow ribs. The RFA value of each implant was measured in buccal and mesial directions after tightening the Smartpegs with 1, 3, 4, 8, 9, 10, and 11 Ncm. Additionally, 4 different examiners measured the RFA after hand tightening the Smartpegs, and the results were compared. The buccal implant stability quotient (ISQ) values when the Smartpegs were tightened to 1Ncm were significantly lower than the ISQ values when the Smartpegs were tightened to 3, 4, 8, 9, 10, and 11 Ncm (P < .05). The mesial ISQ values when the Smartpegs were tightened to 1, 3, and 4 Ncm were significantly lower than the ISQ values when the Smartpegs were tightened with higher torque values (P < .05). The buccal measurements made by 1 examiner was significantly lower than 3 Ncm (P < .05), and the buccal measurements made by 1 examiner was significantly lower than 4 Ncm (P < .05). The mesial ISQ values measured by 2 examiners were significantly lower than 3 Ncm (P < .05), and the mesial ISQ values measured by the other 2 examiners were significantly lower than 8 Ncm (P < .05). The tightening of the Smartpegs should be standardized by the manufacturer to a range of 5-8 Ncm in order to gain reliable objective RFA values, instead of leaving it to subjective finger pressure.
本研究的目的是为磁性射频分析设备（RFA）的Smartpegs拧紧找到一个最佳值。在3根牛肋骨中植入了30颗种植体。在用1、3、4、8、9、10和11 Ncm的扭矩拧紧Smartpegs后，在颊侧和近中方向测量每个种植体的RFA值。此外，4名不同的检查者在手动拧紧Smartpegs后测量RFA，并比较结果。当Smartpegs拧紧至1Ncm时的颊侧种植体稳定性商（ISQ）值显著低于当Smartpegs拧紧至3、4、8、9、10和11 Ncm时的ISQ值（P <.05）。当Smartpegs拧紧至1、3和4 Ncm时的近中ISQ值显著低于当Smartpegs用更高扭矩值拧紧时的ISQ值（P <.05）。1名检查者进行的颊侧测量显著低于3 Ncm（P <.05），1名检查者进行的颊侧测量显著低于4 Ncm（P <.05）。2名检查者测量的近中ISQ值显著低于3 Ncm（P <.05），另外2名检查者测量的近中ISQ值显著低于8 Ncm（P <.05）。Smartpegs的拧紧应由制造商标准化为5-8 Ncm的范围，以便获得可靠的客观RFA值，而不是依赖主观的手指压力。
