摘 要:目的:通过X线头影测量,分析SGTB矫治器对生长发育高峰期AngleⅡ类1分类骨性错畸形病人进行矫治的临床效果。方法:选取生长发育高峰期AngleⅡ类1分类错畸形伴骨性下颌后缩的病例40例,随机分成2组,S组采用Ⅰ期SGTB矫治器导下颌向前联合Ⅱ期固定矫治;F组采用Ⅰ期固定矫治联合Ⅱ期Forsus矫治器导下颌向前。在治疗前、后拍摄X线头颅侧位片,利用Pancherz测量分析法进行分析,比较2组治疗前后的相关指标情况。结果:治疗前2组间病人的各指标测量数据比较差异均无统计学意义(P>0.05)。治疗后,F组L1-MP高于S组(P<0.05)。与治疗前比较,2组病人治疗后SNB、B/OLP、Pg/OLP、Pg/OLP+Co/OLP、ii/OLP、mi/OLP均增大,ANB、is/OLP、U1-NSL、is/OLP-ii/OLP、ms/OLP-mi/OLP、is/OLP-A/OLP均减小,F组L1-MP增大,S组ii/OLP-Pg/OLP减少,差异均有统计学意义(P<0.05~P<0.01);其余各指标治疗前后差异均无统计学意义(P>0.05)。在前牙覆盖的纠正中,S组牙性和骨性因素所占比分别为43%、57%,F组分别为56%、44%;在磨牙关系的纠正中,S组牙性和骨性因素所占比分别为39%、61%,F组分别为49%、51%,构成比差异均无统计学意义(P>0.05)。结论:SGTB矫治器对AngleⅡ类1分类骨性错畸形具有良好的矫治效果,且在下切牙唇倾的控制方面优于Forsus矫治器。Objective:To analyze the clinical effects of SGTB appliance in the correction of growth peak Angle classⅡdivision 1 skeletal malocclusion using X-ray cephalometric measurement.Methods:Forty cases with Angle classⅡdivision 1 malocclusion deformity complicated with bone retraction of mandible were randomly divided into the group S and group F.The group S and group F were treated with stageⅠSGTB appliance combined with stageⅡfixed mandible and stageⅠfixed appliance combined with stageⅡForsus appliance,respectively.The lateral head X-ray was taken before and after treatment,the Pancherz measurement analysis was used for analysis,and the related indicators in two groups were compared between before and after treatment.Results:Before treatment,there was no statistical significance in the measurement data of each index between the two groups(P>0.05).After treatment,the L1-MP in group F was higher than that in group S(P<0.05).Compared with before treatment,the SNB,B/OLP,Pg/OLP,Pg/OLP+Co/OLP,ii/OLP and mi/OLP increased,and the ANB,is/OLP,U1-NSL,is/OLP-ii/OLP,ms/OLP-mi/OLP and is/OLP-A/OLP decreased in two groups after treatment(P<0.05 to P<0.01).Compared with before treatment,the L1-MP in group F increased,the ii/OLP-PG/OLP in group S decreased after treatment,and the differences of which were statistically significant(P<0.05 to P<0.01).There was no statistical significance in other indexes between before and after treatment(P>0.05).In the correction of anterior overlaying,the proportions of dental and osseous factors in group S was 43%and 57%,repectively.In group F,56%and 44%,repectively,respectively.In the correction of molar relations,the proportions of dental and osseous factors in group S was 39%and 61%,respectively.In group F,49%and 51%,respectively.There was no statistical significance in the constituent ratios of above indexes between the two groups(P>0.05).Conclusions:The SGTB appliance appliance has a good effect on the correction of Angle classⅡdivision 1 skeletal malocclusion,and is better than F
