安氏Ⅰ类错患者下颌Bonwill-Hawley弓形与基骨弓形态相关性的三维测量研究

目的研究安氏Ⅰ类错患者下颌Bonwill?Hawley弓形与基骨弓形态之间的相关性。方法利用CBCT和Mimics10.01软件对32例安氏Ⅰ类错患者的下颌基骨弓进行三维定位和测量，绘制其个体化Bonwill?Hawley弓形，分别测量弓形和基骨弓的长度和宽度，并使用SPSS16.0软件对数据进行比较和相关性分析。结果Bonwill?Hawley弓形与基骨弓在长度与宽度上均具有较高的相关性（r＞0.5）；弓形前段、中段长度和宽度与基骨弓的差异无统计学意义（P＞0.05）；弓形后段长度大于基骨弓后段长度，差异具有统计学意义（t＝2.21，P＝0.03）；弓形后段宽度小于基骨弓后段宽度（t＝2.4...

Summary:目的研究安氏Ⅰ类错患者下颌Bonwill?Hawley弓形与基骨弓形态之间的相关性。方法利用CBCT和Mimics10.01软件对32例安氏Ⅰ类错患者的下颌基骨弓进行三维定位和测量，绘制其个体化Bonwill?Hawley弓形，分别测量弓形和基骨弓的长度和宽度，并使用SPSS16.0软件对数据进行比较和相关性分析。结果Bonwill?Hawley弓形与基骨弓在长度与宽度上均具有较高的相关性（r＞0.5）；弓形前段、中段长度和宽度与基骨弓的差异无统计学意义（P＞0.05）；弓形后段长度大于基骨弓后段长度，差异具有统计学意义（t＝2.21，P＝0.03）；弓形后段宽度小于基骨弓后段宽度（t＝2.42，P＝0.02），差异具有统计学意义。结论安氏Ⅰ类错患者下颌Bonwill?Hawley弓形与基骨弓形态之间具有较高的相关性。

Objective To investigate the correlation between mandibular Bonwill-awley arch and base bone archshape.Methods CBCT and Mimics10.01software were used to locate and measure the mandibular arch of32patients with typeⅠmalocclusion.The individualized Bonwill?Hawley arch was drawn and the length and width of the arch and base arch were measured,and the data were compared and analyzed by SPSS16.0software.Results Pearson correlation analysis results showed significant correlation between Bonwill?Hawley arch and base bone arch in both length and width(r>0.5).Compared with base bone arch,anterior(t=0.81,P=0.25)and medium(t=0.69,P=0.50)Bonwill?Hawley arch showed no statistical difference in both length and width(P>0.05),while posterior BonwillHawley arch showed significant statistical difference in length(t=2.21,P=0.03)and width(t=2.42,P=0.02).
