摘要
目的:探讨正畸治疗青少年安氏Ⅱ类错畸形治疗前后错程度及美观效果变化。方法:选取笔者医院口腔科2014年1月-2016年1月收治的50例安氏Ⅱ类错畸形的青少年患者作为观察组,并选取30例门诊诊断为安氏Ⅱ类错畸形但未接受治疗的患者作为对照组。观察组患者均接受正畸治疗,并于治疗前、治疗后6个月、12个月、18个月进行指数评分量表(IOTN-AC)和美观期待值评价;对照组患者在治疗前(初次)和随访18个月时(末次)进行了这些美观效果评估。对观察组患者治疗前后的前牙覆盖、磨牙咬合关系、中线关系、前牙覆等牙颌畸形指标及软组织情况进行评价,比较患者治疗前后相关指标的差异。结果:观察组患者在治疗前、治疗后6个月、12个月、18个月四个时间点的IOTN-AC分值逐渐降低,美观期待值逐渐升高,每个评估时间点的IOTN-AC、美观期待值与前次的值比较均有显著性差异(P<0.05)。观察组与对照组患者在初次(治疗前)评估时的美观效果无显著性差异(P>0.05);而观察组在末次(治疗后18个月)的IOTN-AC分值明显低于对照组,其美观期待值明显高于对照组(P<0.05);对照组患者初次与末次的IOTN-AC与美观期待值比较无显著性差异(P>0.05)。观察组患者治疗后的前牙覆盖、磨牙咬合关系、中线关系、前牙覆等畸形程度评分均明显低于治疗前(P<0.001)。观察组患者治疗后的软组织面角、全面凸角、下唇基角、上下唇角、下唇倾角、Eangle角、Z角UL、Z角LL均明显低于治疗前,而面型角、面凸角、鼻唇角、唇基角、颏唇沟角、鼻唇角、上唇倾角、H角(软)、H角等指标均明显高于治疗前(P<0.05)。结论:正畸治疗青少年安氏Ⅱ类错畸形临床疗效显著,能有效提高患者牙列美观程度,显著降低患者错畸形严重程度,值得在临床推广应用。
Objective To investigate the aesthetic effects of orthodontic treatment for ClassⅡmalocclusion in adolescents and the severity of malocclusion before and after treatment.Methods Fifty adolescents with Class II malocclusion who underwent orthopedics from January 2014 to January 2016 in our hospital were recruited into this study as observation group,and thirty patients diagnosed as Class II malocclusion without ambulation were taken as control group.All patients in observation group were treated with orthodontic therapy.The scores of IOTN-AC and the values of aesthetic expectation were evaluated in the patients in observation group at four time points such as before treatment,6 months,12 months and 18 months after treatment,and the same indexes of aesthetic effects were evaluated in the patients in control group before treatment(the first valuation time)and at 18 months of follow-up(the last valuation time).The tooth and jaw deformity indicators including anterior coverage,molar occlusion,midline relationship and dental overbite denture and soft tissue conditions were assessed in the patients of observation group,and the differences of these indicators were compared before and after treatment.Results The scores of IOTN-AC gradually decreased and the values of aesthetic expectation gradually increased in the four time points in the patients of observation group.Moreover,the scores or values of each time point were significant different from those of the previous one(P<0.05).There was no significant difference in the aesthetic effects between the observation group and the control group at the first valuation time(before the treatment)(P>0.05).However,the score of IOTN-AC of the observation group was significantly lower than that of the control group the last valuation time(18 months after treatment/of follow-up),and the aesthetic expectation value of the observation group was significantly higher than that of the control group(P<0.05).In the control group,There was no significant difference in the aesthetic effect
