Dental implants can cause complications, including the loosening of the abutment screw or fracture. However, there is no standardized technique for removing broken abutment screws. This necessitates further research.
This study aimed to measure heat generation during screw removal to better understand its implications for dental implant procedures.
The experimental setup involved using synthetic bone blocks and titanium implants. An ultrasonically operated instrument tip was utilized for screw removal. Infrared thermometry was employed for accurate temperature measurement, considering factors such as emissivity and distance. Statistical analysis using linear regression and ANOVA was conducted.
The findings revealed an initial rapid temperature increase during the removal process, followed by a gradual decrease. The regression model demonstrated a strong correlation between time and temperature, indicating the heat generation pattern.
Heat generation during screw removal poses risks such as tissue damage and integration issues. Clinicians should minimize heat risks through an intermittent approach. The lack of a standardized technique requires further research and caution. Understanding the generated heat optimizes implant procedures.
种植牙可能会引发并发症，包括基台螺丝松动或基台螺丝折断。但是，折断的基台螺丝取出目前还没有标准化的技术，这需要进一步的研究。
本研究旨在测量螺丝取出过程中的产热情况，以便更好地了解其对种植牙手术的影响。
实验设置使用了合成骨块和钛种植体。采用超声驱动器械的工作尖来取出螺丝。考虑到发射率和距离等因素，使用红外测温技术进行精确的温度测量。采用线性回归和 ANOVA 进行统计分析。
研究结果显示，在螺丝取出过程中，温度会先快速升高，然后逐渐降低。回归模型表明，时间和温度之间存在很强的相关性，反映了产热模式。
螺丝取出过程中的产热会带来组织损伤和整合问题等风险。临床医生应通过间歇性方法将热风险最小化。由于缺乏标准化的技术，因此需要进一步研究和谨慎操作。了解产生的热量可以优化种植牙手术。
