摘　　要：目的比较上海地区不同垂直骨面型成人各牙临床冠中心高度差异,得出临床冠中心高度平均值。方法选择符合纳入标准的高角、均角、低角上海地区成人各50例,测量3组人群各同名牙临床冠中心高度并对3组间差异进行统计学分析。结果高角组各同名牙临床冠中心高度大于均角组但无统计学差异(P>0.05),高角组及均角组各同名牙临床冠中心高度均大于低角组并有统计学差异(P<0.05)。结论直丝弓托槽应粘结在临床冠的中心位置,高角及均角患者粘结高度大于低角患者,正畸医师需根据患者的垂直骨面型对托槽粘结高度做适当调整。Objective To compare the center heights of clinical crowns of the adults with different vertical facial skeletal patterns in Shanghai and obtain the average value of the center heights of clinical crowns. Methods 50 high angle ,50 average angle and 50 low angle adults in Shanghai were selected according to the inclusion criteria. The center heights of clinical crowns of the same teeth in three groups were measured and the differences between them were statistically analyzed. Results The center heights of clinical crowns of the same teeth in high angle group were higher than those in the average angle group, but there was no significant difference （P 〉 0.05 ）. The center heights of clinical crowns of the same teeth in high angle group and average angle group were all higher than those in low angle group and there was significant statistical difference between them （ P 〈 0.05 ）. Conclusions The straight - wire brackets should be placed in the center of clinical crowns. The bending heights of the high and average angle patients should be greater than those of the low angle patients. The doctor should determine the bonding height of brackets according to the vertical facial skeletal pattern of each patient.
