摘要
目的 探讨隐形矫治器治疗上颌牙弓狭窄对牙弓宽度及牙槽骨形态的影响。方法 选取2021年1月至2023年1月郑州小老虎口腔医院收治的82例上颌牙弓狭窄患者为研究对象,按随机数表法分为隐形矫治器组和金属托槽矫治器组,各41例。金属托槽矫治器组以金属托槽矫治器治疗,隐形矫治器组以隐形矫治器治疗。比较两组矫正24个月后临床疗效,矫正前、矫正24个月后牙弓宽度,矫正前、矫正12个月、矫正24个月后牙槽骨形态,矫正前、矫正24个月后牙齿美观度,矫正后3个月患者满意度及矫正期间并发症发生率。结果 两组一般资料经比较,差异无统计学意义(P>0.05)。隐形矫治器组治疗有效率高于金属托槽矫治器组,差异有统计学意义(P<0.05)。矫正24个月后,隐形矫治器组尖牙区、第一前磨牙区、第二前磨牙区及第一恒磨牙区牙弓宽度均高于金属托槽矫治器组,差异有统计学意义(P<0.05)。两组不同时间点牙槽骨远中、近中、颊侧及舌侧高度时间、组间、交互比较,差异有统计学意义(P<0.05),且隐形矫治器组各高度值均高于金属托槽矫治器组,差异有统计学意义(P<0.05)。矫正24个月后,隐形矫治器组红色美学指数(PES)评分高于金属托槽矫治器组,差异有统计学意义(P<0.05)。矫正后3个月,隐形矫治器组患者各项满意度评分均高于金属托槽矫治器组,差异有统计学意义(P<0.05)。两组并发症发生率比较,差异无统计学意义(P>0.05)。结论 隐形矫治器治疗上颌牙弓狭窄疗效确切,可有效改善患者牙弓宽度及牙槽骨形态,且安全性较好,值得临床应用。
Objective To investigate the effects of invisible orthodontic appliances in treating maxillary arch narrowing on dental arch width and alveolar bone morphology.Methods A total of 82 patients with maxillary arch narrowing treated at Zhengzhou Little Tiger Dental Hospital from January 2021 to January 2023 were selected as study subjects.They were randomly divided into an invisible orthodontic appliance group and a metal bracket orthodontic appliance group,with 41 cases in each group.The metal bracket group was treated with metal brackets,while the invisible appliance group was treated with invisible orthodontic appliances.Clinical efficacy after 24 months of correction,dental arch width before and after 24 months of correction,alveolar bone morphology before correction,after 12 months,and after 24 months of correction,dental aesthetics before and after 24 months of correction,patient satisfaction three months post-treatment,and complication rates during orthodontic treatment were compared.Results No significant differences were observed in general demographic characteristics between the two groups(P>0.05).The treatment efficacy rate was higher in the invisible orthodontic appliance group than in the metal bracket group,with statistically significant difference(P<0.05).After 24 months of correction,the dental arch widths in the cuspid,first premolar,second premolar,and first molar regions in the invisible appliance group were higher than those in the metal bracket group,with statistically significant differences(P<0.05).The heights of the alveolar bone in the distal,mesial,buccal,and lingual aspects at different time points,comparisons between groups,and interactions showed significant differences(P<0.05).All alveolar bone height values in the invisible appliance group were higher than those in the metal bracket group,with statistically significant differences(P<0.05).After 24 months of correction,the Pink esthetic score(PES)score was higher in the invisible appliance group than in the metal bracket group,with a significant difference(P<0.05).Three months post-treatment,patient satisfaction scores in the invisible appliance group were higher than in the metal bracket group,with significant differences(P<0.05).No significant difference was found between the two groups in complication rates(P>0.05).Conclusion Invisible orthodontic appliances are effective in treating maxillary arch narrowing,significantly improving dental arch width and alveolar bone morphology,with good safety,and are worthy of clinical application.
