PurposeTo assess how well torque‐limiting devices (TLDs) are known and used by European dentists, and their adherence to screw tightening protocols and screw loosening occurrence through a survey, including the correlation between the dental specialty‐of‐interest and the recognition, the tightening protocol used, and between the calibration and the occurrence of screw loosening.Materials and methodsA 10‐question survey was distributed to dentists to collect data on their specialty‐of‐interest, TLD usage, knowledge on TLDs, calibration, the term “preload,” tightening speed, tightening protocols used, and occurrence of screw loosening. Pearson test was used for correlation analysis between the specialty‐of‐interest and the recognition‐based questions, the tightening protocol used, and between the calibration and the frequency of screw loosening.ResultsOf 422 respondents, 24% calibrated their TLDs, 27% knew the term “preload,” 76% selected the correct location to read on TLDs, and 6% was aware of the effect of tightening speed. The correlation between the specialty‐of‐interest and the recognition‐based questions was nonsignificant (p < .05) but was significant for used tightening protocol (p < .001). The correlation between the calibration and the occurrence of screw loosening was nonsignificant (p = 0.16). Tightening protocols' effect on screw loosening was similar, which was mostly observed less than once a year (p < .001).ConclusionsA lack in dentists' knowledge was found on calibration, the term preload, and the effect of tightening speed, which were not impacted by the dentists' specialty‐of‐interest, which affected the preferred tightening protocol. The tightening protocol and calibration did not impact the occurrence of screw loosening, which was mostly observed less than once a year.

欧洲牙科临床医生扭矩限制装置使用情况调查


目的通过一项调查评估欧洲牙医对扭矩限制装置 （TLD） 的了解和使用程度，以及他们对螺钉拧紧方案和螺钉松动发生率的遵守情况，包括感兴趣的牙科专业与认可、使用的拧紧方案以及校准与螺钉松动发生之间的相关性。材料和方法向牙医分发了一份包含 10 个问题的调查，以收集有关他们感兴趣的专业、TLD 使用情况、TLD 知识、校准、术语“预紧力”、拧紧速度、使用的拧紧协议以及螺钉松动发生率的数据。Pearson 检验用于分析感兴趣的专业和基于识别的问题、使用的拧紧方案以及校准与拧松频率之间的相关性。结果在 422 名受访者中，24% 校准了他们的 TLD，27% 知道“预加载”一词，76% 选择了正确的 TLD 读取位置，6% 知道收紧速度的影响。感兴趣的专业和基于识别的问题之间的相关性不显著 （p < .05），但对于使用的紧缩方案 （p < .001） 是显著的。校准与螺钉松动发生之间的相关性不显著 （p = 0.16）。拧紧方案对螺钉松动的影响相似，大多数每年观察到不到一次 （p < .001）。结论发现牙医缺乏关于校准、术语预紧力和拧紧速度影响的知识，这些知识不受牙医感兴趣的专业的影响，这影响了首选的拧紧方案。 拧紧方案和校准不会影响螺钉松动的发生，大多数情况下每年观察到不到一次。
