A device to measure bur temperature using thermocouple technology was developed. A block of bovine bone was subjected to computerized tomography scanning to confirm bone density and configuration similar to that of a human mandible. Bone temperature was measured via a thermocouple probe. During osteotomy preparation, bur temperature was shown to exceed the surrounding bone temperature. Irrigation greatly reduced bur temperature. Osteotomies were made to depths of 8.5, 10.5, 13.5, 15.5, 18.5, and 20.5 mm. Bone density played a far greater role in bur temperature elevation than did osteotomy depth. Adding a pilot drill to the drill sequencing tended to lower bur temperature; widening of osteotomies from 2 to 3 mm wide generated as much heat as did the making of the 2-mm-wide osteotomy.
研发了一种使用热电偶技术测量牙钻温度的装置。对一块牛骨进行计算机断层扫描，以确认其骨密度和结构与人类下颌骨相似。通过热电偶探头测量骨温。在截骨术准备过程中，牙钻温度显示超过周围骨温。冲洗可大幅降低牙钻温度。截骨深度分别为8.5、10.5、13.5、15.5、18.5和20.5毫米。骨密度对牙钻温度升高的影响远大于截骨深度。在钻孔顺序中增加导向钻往往会降低牙钻温度；将截骨宽度从2毫米扩大到3毫米产生的热量与制作2毫米宽的截骨术产生的热量相同。
