【摘要】：目的:分析伴有颞下颌关节紊乱病(TMD)的安氏Ⅱ类错患者在CO-CR位的髁突位置变化。方法:利用髁突移位测量仪(MCD)记录15例伴有TMD的安氏Ⅱ类错患者CO-CR位的髁突位置。结果:15例患者髁突CO-CR位矢状向偏移量均值左侧为0.99 mm;右侧1.22 mm,左右髁突矢状向偏移量均有统计学意义;矢状向上70.0%(21/30)CR位髁突位于CO位的后方,其中左侧比率为66.7%(10/15)。垂直向偏移量均值左侧为1.09 mm,右侧1.37 mm,左右髁突垂直向偏移量均有统计学意义;垂直向63.3%(19/30)CR位髁突位于CO位的上方,其中左侧比率为60.0%(9/15)。髁突垂直向偏移量均值(1.23 mm)髁突矢状向偏移量均值(1.10 mm),但差异无统计学意义。髁突横向偏移量均值为0.54 mm,髁突在横向偏移量有统计学意义;53.3%(8/15)CR位髁突位于CO位的右方。结论:伴有TMD的安氏Ⅱ类错患者存在着CO-CR位髁突位置不一致,正畸治疗前应充分考虑患者的髁突位置以便制定科学的治疗方案。
[Abstract]:Objective: to analyze the condylar position of (TMD) patients with temporomandibular disorders (TMJ). Methods: (MCD) was used to record the condylar position of CO-CR in 15 patients with TMD. Results: the mean sagittal deviation of condylar CO-CR in 15 patients was 0.99 mm; and 1.22 mm, respectively. Sagittal upward 70.0% (21 / 30) of the CR condyle was located behind the CO position, with a left ratio of 66.7% (10 / 15). The mean vertical migration of the condyle was 1.09 mm, on the left side and 1.37 mm, on the right side. There was statistical significance in the vertical migration of the condyle. Vertical 63.3% (19 / 30) of the condyle of CR is located at the top of the CO position, with a left side ratio of 60.0% (9 / 15). The mean value of condylar vertical deviation (1. 23 mm) and condylar sagittal deviation (1. 10 mm),) had no statistical significance. The mean transverse migration of condyle is 0. 54 mm, condyle and 53.3% (8 / 15) of CR condyle is located on the right side of CO position. Conclusion: the condylar position of CO-CR is not consistent in the patients with TMD. The condylar position of the patients should be considered before orthodontic treatment in order to make a scientific treatment plan.
