The study aimed to investigate the cooling performance of three different surgical methods for bone splitting during implant dentistry procedures.
An in vitro study was conducted on bovine ribs to test the cooling performance of three osteotomy methods: conventional osteotomy with standard cooling irrigation, template-assisted osteotomy with standard cooling irrigation, and modified template-assisted osteotomy with additional cooling fluid through internal irrigation channels in the surgical guide. A negative control group without cooling was also included. Temperature measurements were taken during the procedures using a contactless infrared thermometer.
The results showed that the conventional osteotomy without cooling resulted in the highest mean of the peak temperatures (114.7 °C ± 45.4), while the modified template-assisted osteotomy with additional cooling achieved the lowest mean of the peak temperatures (29.4 °C ± 7). Statistically significant differences in temperature were observed among the groups (p < 0.001).
The study rejected the null hypothesis and demonstrated that the cooling method used during bone splitting procedures significantly affected the temperature development at the surgical site. The modified template-assisted osteotomy with additional cooling provided the best cooling performance. However, caution should be exercised in interpreting the results due to the limitations of the in vitro study. Further research with stronger external validity is needed to confirm these findings and explore their applicability in clinical settings to benefit patients.
本研究旨在探讨种植牙科手术中三种不同骨切开方法的冷却性能。
在牛肋骨上进行了一项体外研究,以测试三种截骨方法的冷却性能:常规截骨伴标准冷却冲洗、模板辅助截骨伴标准冷却冲洗,以及在手术导板的内部灌溉通道中增加冷却液的改良模板辅助截骨。还包括一个无冷却的阴性对照组。使用非接触式红外测温仪在手术过程中进行温度测量。
结果表明,无冷却的常规截骨导致的最高峰值温度平均值最高(114.7°C±45.4),而附加冷却的改良模板辅助截骨的峰值温度平均值最低(29.4°C±7)。组间温度差异有统计学意义(p<0.001)。
本研究拒绝了零假设,并证明了在骨切开过程中使用的冷却方法显著影响了手术部位的温度发展。附加冷却的改良模板辅助截骨提供了最佳的冷却性能。然而,由于体外研究的局限性,在解释结果时应谨慎。需要进一步具有更强外部有效性的研究来证实这些发现,并探索其在临床环境中的适用性,以造福患者。
