Abstract:
Objective:To analyze the dental and mandibular asymmetry of adults with Class Ⅱ subdivision malocclusion.Methods:The jaw bones of 30 adults with Class Ⅱ subdivision malocclusion(case group)and 30 with normal-occlusion(control group)were scanned by CBCT.Linear and angular comparison was conducted between the two groups.Results:Dental midline deviation was ob-served in case group,mostly in mandibular arch (60%).The development of Class Ⅱ molar relationship correlated mainly to distally positioned mandibular molar on Class Ⅱ side.Conclusion:In the adults with Class Ⅱ subdvision malocclusion odontogenic asymme-try is the major factor,bony asymmetry is the miner.
