摘　　要：目的分析固定矫治器与斜面导板联合矫治安氏Ⅱ类1分类错[牙合]的疗效。方法选取2020年10月—2023年10月新沂市人民医院口腔科收治的99例安氏Ⅱ类1分类错[牙合]患者作为研究对象,根据不同矫治方法分为两组,对照组(n=45,固定矫治器)、观察组(n=54,固定矫治器结合斜面导板)。比较两组患者矫治情况(牙齿排列、后牙边缘嵴高度、牙根远近中倾斜度)、模型测量值(覆合、覆盖)、临床疗效。结果治疗前,两组矫治情况各项评分、模型测量值对比,差异无统计学意义(P均>0.05)。治疗后,两组牙齿排列、后牙边缘嵴高度、牙根远近中倾斜度评分及覆合、覆盖值均低于治疗前,且观察组牙齿排列、后牙边缘嵴高度及牙根远近中倾斜度评分均低于对照组,差异有统计学意义(P均<0.05)。治疗后,组间模型测量对比,观察组覆盖值低于对照组,差异有统计学意义(P<0.05)。观察组治疗有效率(98.15%)(53/54)高于对照组(86.67%)(39/45),差异有统计学意义(χ^(2)=4.924,P<0.05)。结论安氏Ⅱ类1分类错[牙合]患者矫治中选择固定矫治器联合斜面导板,矫治效果更佳,覆盖关系有所改善的同时,临床疗效更加显著。Objective To analyze the curative effect of fixed appliance and inclined guide combined with correction of ANSI Class Ⅱ 1 classification malocclusion.Methods Ninety-nine patients with ANSI Class Ⅱ 1classification malocclusion admitted to the stomatology department of Xinyi People's Hospital from October 2020 to October 2023 were selected as the study objects and divided into two groups by envelope method:control group(n=45,fixed appliance) and observation group(n=54,fixed appliance combined with inclined guide plate).The treatment(tooth arrangement,posterior marginal ridge height,root inclination),model measurement(overbite,overjet) of the two groups were compared.Results Before treatment,there was no significant difference in scores and model measurements between the two groups(all P>0.05).After treatment,the tooth arrangement,posterior edge ridge height,root slope score,overlay and covering values in both groups were lower than before treatment.The scores of tooth arrangement,the ridge height at the posterior edge of the teeth and the tooth slope in the observation group were lower than those in the control group,and the differences were statistically significant(all P<0.05).After treatment,the model measurement between groups showed that the coverage value of observation group was lower than that of control group,and the difference was statistically significant(P<0.05).The effective rate of the observation group(98.15%)(53/54) was higher than that of the control group,and the difference was statistically significant(86.67%)(39/45)(χ^(2)=4.924,P<0.05).Conclusion The combination of fixed appliance and inclined guide in the treatment of ANSI class Ⅱ 1 classificantion malocclusion malocclusion patients has better treatment effect,and the clinical effect is more significant while the coverage relationship is improved.
