安氏Ⅰ类错(牙合)患者下颌Bonwill-Hawley弓形与基骨弓形态相关性的三维测量研究
Three dimensional measurement study of the correlation between the mandibular Bonwill-Hawley arch form and base bone arch shape in ClassⅠmalocclusion patients
摘要
Abstract
Objective To investigate the correlation between mandibular Bonwill-Hawley arch and base bone archshape. Methods CBCT and Mimics10.01 software were used to locate and measure the mandibular arch of 32 patients 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 SPSS 16.0 software. 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 Bonwill-Hawley arch showed significant statistical difference in length (t=2.21, P=0.03) and width (t=2.42, P=0.02). Conclusion There was significant correlation between Bonwill-Hawley arch and base bone arch in both length and width.关键词
