摘要
目的:探究钛金属微种植体支抗治疗成人骨性Ⅱ类错(牙合)的效果及对侧貌观的影响。方法:回顾2019年12月-2020年10月来本院接受治疗的90例成人骨性Ⅱ类错(牙合)的临床资料,按照治疗方法分为两组,对照组(n=45)行口外弓支抗治疗,观察组(n=45)行钛金属微种植体支抗治疗,对比两组治疗效果,评估治疗前及治疗后1个月咀嚼功能、牙齿咬合力、头影测量指标,统计矫正满意度。结果:观察组治疗总有效率较对照组高,差异有统计学意义(χ^(2)=4.939,P=0.026)。治疗后1个月,两组牙齿咬合力及咀嚼功能均较治疗前提高,而且观察组较对照组高(P<0.05)。观察组矫正满意度及外观美容效果、舒适程度、咀嚼功能、矫正效果评分均较对照组高(P<0.05)。治疗后1个月,两组U6-Ptm、U1-L1水平均较治疗前显著增加,ANB、L1-MP、U1-Ptm、U1-SN、OB、OJ较治疗前明显缩小,两组U1-L1、Ul-SN、OJ、U6-Ptm、U1-Ptm、L1-MP水平变化量对比,差异有统计学意义(P<0.05),观察组U1-L1、U1-SN、OJ、U6-Ptm、U1-Ptm、L1-MP水平变化量大于对照组,差异有统计学意义(P<0.05)。结论:钛金属微种植体支抗治疗能够改善临床特征,提高牙齿咬合力及咀嚼功能,提高矫正满意度,显著改善侧貌观,改善外观,值得推广。
Objective:To explore the effect of titanium microimplant anchorage in the treatment of adult patients with skeletal classⅡmalocclusion and its effect on lateral view.Method:The clinical data of 90 adult patients with skeletal classⅡmalocclusion in our hospital from December 2019 to October 2020 were reviewed and divided into two groups according to the treatment methods.Patients in the control group(n=45)were treated with extermal arch anchorage therapy,while patients in the observation group(n=45)were treated with titanium microimplant anchorage treatment.The therapeutic effects of the two groups were compared and the masticatory function,teeth bite force and cephalic shadow index of the two groups were evaluated before and one month after treatment,and the corrective satisfaction of the two groups was counted.Result:The total effective rate of the observation group was higher than that of the control group(χ^(2)=4.939,P=0.026).One month after treatment,the bite force and masticatory function in both groups were improved compared with those before treatment,and the observation group was higher than the control group(P<0.05).The correction satisfaction,aesthetic effect,comfort degree,masticatory function and correction effect scores of patients in the observation group were higher than those in the control group(P<0.05).One month after treatment,the levels of U6-PTM and U1-L1 in both groups increased significantly compared with before treatment,while the levels of ANB,L1-MP,U1-PTM,U1-SN,OB and OJ decreased significantly compared with before treatment.There were statistically significant differences in the changes of U1-L1,U1-SN,OJ,U6-PTM,U1-PTM and L1-MP between the two groups(P<0.05).The changes of U1-L1,U1-SN,OJ,U6-PTM,U1-PTM and L1-MP in the observation group were higher than those in the control group(P<0.05).Conclusion:Titanium microimplant anchorage therapy can imporve the clinical characteristics,improve the bite force and chewing function of teeth,improve the satisfaction of correction,significantly improve the profile view,and is worthy of promotion.
