OBJECTIVE
Irrigation with saline is one of the essential methods for reducing the heat generated during dental implant osteotomy. High irrigation volume impairs visibility of the surgical field, thus complicates the surgery. In this study, we aimed to determine the optimal irrigation volume for heat reduction during dental implant drilling.
MATERIALS AND METHODS
Thirty-two implant osteotomies were prepared on four fresh cow ribs. Heat generated during the final implant drilling was measured both with infrared thermography and thermocouple method. Initial and maximum temperatures were measured at four different irrigation volumes; 32, 44, 56, and 68 ml/min.
RESULTS
Both measurement methods showed that the amount of temperature rise is associated with the irrigation volume during implant drilling. There is no further decrease in temperature rise above irrigation volume of 56 ml/min.
CONCLUSION
Saline irrigation with 56 ml/min provides sufficient heat reduction during dental implant drilling and higher irrigation volumes are not necessary.
目的
用生理盐水冲洗是减少牙种植体截骨术中产生热量的重要方法之一。高冲洗量会影响手术视野的清晰度，从而使手术复杂化。在本研究中，我们旨在确定牙种植体钻孔过程中减少热量的最佳冲洗量。
材料与方法
在四根新鲜牛肋骨上制备32个种植体截骨术。在最终种植体钻孔过程中产生的热量通过红外热成像和热电偶方法进行测量。在四种不同冲洗量下测量初始温度和最高温度；分别为32、44、56和68毫升/分钟。
结果
两种测量方法均表明，种植体钻孔过程中温度升高的幅度与冲洗量有关。冲洗量高于56毫升/分钟时，温度升高不再进一步降低。
结论
56毫升/分钟的生理盐水冲洗在牙种植体钻孔过程中可提供足够的热量减少，无需更高的冲洗量。
