PURPOSE: Few studies have evaluated the outcomes of @entity346 ( @entity346 ) for the correction of skeletal @entity3233 with an anterior open bite and the potential for postoperative relapse. Therefore, this study evaluated the stability of outcomes of @entity346 for mandibular prognathism with and without an anterior open bite. MATERIAL AND METHODS: This retrospective cohort study included consecutive @entity1 with skeletal @entity3233 with (AOB group) and without (NAOB group) an anterior open bite who underwent @entity346 at Yonsei Dental Hospital (Seoul, Korea). Lateral cephalograms were analyzed for predictor (open bite, yes or no) and outcome (horizontal and vertical relapse in the mandible) variables before and 7  days, 1  year, and 2  years after surgery. Other variables included the @entity1 ' demographic characteristics. Data were analyzed using independent t tests, repeated measures analysis of variance, Pearson correlation coefficients, and multiple linear regression analysis. RESULTS: The 2 groups (n  = 15 each) were matched for baseline demographic characteristics. During the 2-year postoperative period, anterior and superior mandibular movements were observed in the NAOB group, whereas posterior and superior movements were observed in the AOB group. However, there were no meaningful intergroup differences in horizontal and vertical relapses of the mandible at all time points, although the amount of postoperative inferior relapse increased with a decrease in the amount of initial overbite. CONCLUSIONS: @entity346 for the correction of skeletal @entity3233 resulted in good postoperative stability over time, regardless of the presence of a preoperative open bite, although the amount of postoperative inferior relapse showed a weak negative correlation with the initial overbite. Thus, @entity346 can be a clinically acceptable treatment for skeletal @entity3233 with an anterior open bite.
