Abstract:
0.05). Mean follow up periods were 10.77 months for BSSRO group and 11.28 months for DO group, respectively. After mandibular advancement, mean positional changes in the condyle were 0.56+/-1.43 mm horizontally and 0.72+/-1.61 mm vertically for BSSRO group and 0.53+/-1.56 mm horizontally and 0.56+/-1.75 mm vertically for DO group, respectively. Mean change of distance from B point to Y-axis was -1.76+/-0.83 mm for BSSRO group and -2.14+/-1.82 mm for DO group, respectively. According to the condylar position and B point, there were no significant differences in postoperative stability between the two groups (P>0.05).CONCLUSION: There was no significant difference in postoperative stability between DO and BSSRO group according to condylar position and B point. Based on the results of the present study, it is hypothesized that DO would be a good treatment choice for severe mandibular retrognathism because DO could achieve more mandibular advancement and concurrent soft tissue elongation.]]>
