PURPOSE: To analyze the relationship between upper airway and mandible morphology in patients with skeletal Class Ⅱ malocclusion with cone-beam CT (CBCT).
METHODS: Thirty-three volunteers with individual normal occlusion and thirty-three patients with skeletal Class Ⅱ malocclusion were selected to undergo CBCT. All samples were outputted to Dicom and reconstructed using Mimics 19.0 medical software． SPSS 19.0 software package was used to analyze the differences between the two groups. Correlation between the two groups was evaluated using Pearson's coefficient analysis． RESULTS: Fifteen parameters showed significant difference between individual normal occlusion and the skeletal Class Ⅱ malocclusion(P<0.05). There were 10 significant correlational parameters between mandible length and upper airway of the skeletal Class Ⅱ malocclusion group． There were 13 significant correlational parameters between the arch width of the maxilla and upper airway of the skeletal Class Ⅱ malocclusion group． There were 3 significant correlational parameters between the arch width of the mandible and upper airway of the skeletal Class Ⅱ malocclusion group． CONCLUSIONS: The upper airway morphology of skeletal Class Ⅱ malocclusion is correlated with maxillary and mandibular parameters．.
