چکیده مقاله:
Background and aim: With the hypothesis that there is an interrelation between the cephalometric characteristics and difference in the arch widths, the aim of this study was to evaluate the relationship between the dental and skeletal features.Materials and methods: Lateral cephalograms and dental casts of ۴۲ untreated cl II div ۱ patients with excessive vertical growth were evaluated for arch widths and cephalometric parameters. Student t -test was used to evaluate the difference of variables with normal distributions and Mann-Whitney as the nonparametric equivalent of t-test.Results: Maxillary arch width in class II div۱ subjects is narrower than normal groups in both genders and mandibular arch width is the same as normal group in females and smaller in males. In females, a moderate to high relationship was seen between cephalometric parameters and arch widths.Conclusion: The existence of relationship between craniofacial dimensions and arch widths should be mentioned in treatment planning to prevent unwanted side effects and relapse.
