目的:为了评估欧洲牙医对扭矩限制装置(TLD)的了解和使用程度,通过调查,他们遵守螺钉拧紧协议和螺钉松动的发生,包括感兴趣的牙科专业和认可之间的相关性,使用的紧缩协议,以及校准和螺钉松动的发生之间。
方法:向牙医分发了10个问题的调查,以收集有关他们感兴趣的专业的数据,TLD使用情况,关于TLD的知识,校准,术语“预加载”,“拧紧速度,使用的紧缩协议,以及螺钉松动的发生。Pearson检验用于感兴趣的专业和基于识别的问题之间的相关性分析,使用的紧缩协议,以及校准和螺钉松动的频率之间。
结果:在422名受访者中,24%校准了他们的TLD,27%的人知道“预加载”这个术语,“76%的人选择了正确的位置在TLD上读取,6%的人意识到收紧速度的影响。感兴趣的专业和基于识别的问题之间的相关性不显着(p<.05),但对于使用的紧缩协议(p<.001)。校准与螺钉松动发生之间的相关性无统计学意义(p=0.16)。拧紧方案对螺钉松动的影响相似,这主要是观察不到一年一次(p<.001)。
结论:发现牙医缺乏校准知识,术语预加载,以及拧紧速度的影响,没有受到牙医感兴趣的专业的影响,这影响了首选的紧缩方案。拧紧协议和校准不会影响螺钉松动的发生。这主要是每年观察不到一次。
OBJECTIVE: To 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.
METHODS: A 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.
RESULTS: Of 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).
CONCLUSIONS: A 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.
