abstract = {ObjectiveLip soft tissue were measured and assessed before and after orthodontic treatment of Class Ⅱ division 1 adults in order to instruct the clinical work.MethodsA total of 30 post-treatment adult patients of Class Ⅱ division 1 were selected, whose post-treatment model and cephalometric data were within the normal range. The pre- and post-treatment front image and lateral cephalograms lip sagittal thickness and vertical thickness measurement.ResultsPost-treatment upper lip vertical become thinner and lower lip vertical thickness is bigger which has a statistically significant gap. Upper lip vermilion of the initial tissue thickness after treatment increased, lower lip vermilion of initial tissue thickness had a tendency to decrease after treatment, and there was statistical significance. The retraction of upper incisor cervical point (U1C) was positively correlated with upper lip retraction (TUL). The retraction of lower incisor cervical point (L1C) was positively correlated with lower lip retraction (TLL). And the retraction of upper incisor most anterior point was positively correlated with lower lip retraction.ConclusionUpper and lower lip retraction in Class Ⅱ division 1 Chinese adults could be effectively predicted by the retraction of incisors after extraction orthodontic treatment.}
