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 type Ⅰ malocclusion. 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.
