摘要： 目的　探讨电子面弓与数显卡尺在颞下颌关节运动测量中的应用效果。方法　选择2020年10月至2022年2月入院的颞下颌关节紊乱病（TMD）16例为研究组，另以16例颞下颌关节健康体检者为对照组，分别行数显卡尺测量与电子面弓检查。比较两组最大开口度、前伸边缘运动、左侧方边缘运动及右侧方边缘运动，并比较其测量的准确性。结果　电子面弓与数显卡尺测量研究组及对照组的最大开口幅度，测量数值无统计学差异（P＞0.05）；电子面弓与数显卡尺测量两组人员的前伸边缘运动、左侧方边缘运动及右侧方边缘运动，研究组距离均高于对照组，有统计学差异（P＜0.05）；电子面弓与数显卡尺分别测量TMD患者的最大开口度、前伸边缘运动、左侧方边缘运动及右侧方边缘运动距离，差异均无统计学意义（P＞0.05）；电子面弓与数显卡尺分别测量对照组人员的最大开口度、前伸边缘运动、左侧方边缘运动及右侧方边缘运动距离，差异均无统计学意义（P＞0.05）。结论　TMD患者常伴有颞下颌关节运动异常，采用电子面弓与数显卡尺均能准确测量颞下颌关节运动情况，前者使用更加方便，功能更全面，能为临床诊疗提供更可靠的参考依据。

Abstract: Objective　To investigate the application effect of electronic facebow and digital caliper in measurement of mandibular movement. Methods　Sixteen patients with temporomandibular disorders (TMD) from October 2020 to February 2022 were selected as the research group. Sixteen healthy subjects were selected as the control group. After admission, both groups underwent digital caliper examination and electronic facebow examination respectively. The maximum opening, protrusive boarder movements, lateral left boarder movements and lateral right boarder movements were compared between the two groups, and the measurement accuracy of different examinations were compared. Results　There was no significant difference in the maximum opening measured by electronic facebow and digital caliper between the research group and control group (P>0.05). The movement distance of protrusion, left laterality and right laterality were measured by electronic facebow and digital caliper. The distance of the study group was higher than that of the control group, and the difference was statistically significant (P<0.05). There was no significant difference in the maximum opening, protrusive boarder movements, lateral left boarder movements and lateral right boarder movements distance of TMD patients measured by electronic facebow and digital caliper (P>0.05). The data of the maximum opening, protrusive boarder movements, lateral left boarder movements and lateral right boarder movements were measured by electronic facebow and digital caliper respectively, and there was no significant difference (P>0.05). Conclusion　TMD patients are often accompanied by TMD movement abnormalities, and both electronic facebow and digital caliper can accurately measure mandibular movement. The former one is more convenient to use and has more comprehensive functions, which can provide a more reliable reference basis for clinical diagnosis and treatment.
