摘要
目的:研究牙种植术中不同钻孔提拉方式及不同冷却系统对术区牙槽骨温度的影响,探讨牙种植术中温度场的变化。方法:制作48个统一标准的模拟骨块,根据不同钻孔提拉方式和不同冷却系统分为6组,每组8个骨块,进行温度场试验,测定不同骨块中温度场的温度最高值。采用SPSS12.0软件包对数据进行单因素方差分析。结果:在相同的钻孔提拉方式下,内冷却系统温度控制方式术区温度低于外冷却系统的温度控制方式:在相同的冷却系统下,2次钻孔提拉方式术区温度低于直接1次钻孔方式。其中,采用内冷却系统进行温度控制时,2次钻孔提拉方式的术区温度最低(P<0.05)。结论:牙种植术中采用多次钻孔提拉方式及内冷却系统的温度控制方式,可以有效降低术区温度,减少手术产热,提高牙种植术成功率。
PURPOSE： To study the effect of different ways of pulling the drilling burs and cooling systems on alveolar bone temperature of the surgical area, and explore the changes of temperature field in dental implants. METHODS： Forty-eight unified standard artificial （nylon） bone blocks were fabricated and divided into 6 groups according to different drilling pulling ways and cooling systems. The changes of bone temperature field were detected in 6 groups, and the highest temperature in temperature field was measured and recorded. The date was analyzed with SPSS 12.0 software package for ANOVA. RESULTS： The temperature in the surgical area using internal cooling systems under the same drilling pulling was lower than using external cooling systems. The temperature in the surgical area using secondary drilling pulling way was lower than using direct drilling methods under the same cooling systems. The temperature in the surgical area using secondary drilling pulling way was the lowest when internal cooling systems was adopted （P〈0.05）. CONCLUSIONS： Drilling pulling way and internal cooling systems can effectively reduce the temperature in the surgical area, lessen heat production and improve the success rate of dental implants.
