Abstract：Objective To provide a clinical reference by comparing the effect of maxillary molars distalization in Angle’s Class Ⅱ malocclusion patients. Methods Forty patients with molar distalization in Angle’s Class Ⅱ malocclusion admitted to our hospital from December 2018 to December 2019 were selected and divided into mean-angle group and low-angle group according to the intersection angle between the mandibular plane and the orbital-ear plane （FH/MP）, with 20 cases in each group. In both groups, the implant-supported maxillary molar distalization were used. The X-ray cephalometric measurements before and after correction, the overall force time used to achieve a neutral relationship of the molar and the satisfaction of the patients after correction were compared between the two groups. Results After correction, there was no statistically significant difference in U1-NA, U1-SN, SNA and overall force time between the mean-angle and low-angle groups （t＝－0.170, －1.000,－0.630,－9.020, all P＞0.05); patient satisfaction was higher in the low-angle group than that in the mean-angle group, with a statistically significant difference between the two groups （χ2＝－3.717,P＜0.05）. Conclusion The method of maxillary molar distalization is recommended for the patients in Angle’s Class Ⅱ malocclusionwith low angle; while the pre-correction facial protuberance and chin morphology should be assessed for patients with mean-angle in order to select an orthodontic solution.
