摘要
目的探讨无托槽矫治与传统固定矫治的效果及牙周健康的比较。方法选取2016年1月~2017年6月我院牙科收治的40例正畸矫治患者作为研究对象,按照入组的先后顺序采用单双号数字法随机分为研究组与对照组,每组各20例。对照组患者采用天天直丝弓托槽矫治,研究组按照设计方案模拟临床矫治,将每个矫治阶段的牙颌模型经三维快速激光成形制作出透明的无托槽矫治器。比较两组患者的矫治效果、牙弓宽度及牙龈指数(GI)、菌斑指数(PLI)。结果研究组患者治疗后的U1-NA角、U1-SN角、牙弓前段长度均显著高于对照组,L1-NB角显著低于对照组,差异有统计学意义(P<0.05);研究组患者治疗后第16周的GI、PLI评分显著低于对照组,差异有统计学意义(P<0.05)。结论无托槽矫治与传统固定矫治比较,可更好地降低后牙高度,预防前牙唇倾,矫治效果优,口腔及牙龈卫生更良好。
Objective To investigate the effect of orthodontic treatment in bracketless appliance or traditional fixed appliance and comparison of periodontal health.Methods From January 2016 to June 2017,40 patients accepted orthodontic treatment in Department of Dentistry of our hospital were selected as the subject,and divided into research group and control group by odd or even number of their enrollment sequency,20 cases in each group.In the control group,patients were treated with straight wire bow bracket every day.In the research group,following the design protocol for clinical correction,the transparent bracket-free appliance for dental jaw model was created via a three-dimensional rapid laser in each stage of orthodontic treatment.The orthodontic treatment effect,dental arch width,gingival index（GI）,and plaque index（PLI） were compared between the two groups.Results After treatment,the U1-NA angle,L1-NB angle,and the length of anterior segment of the dental arch in the research group were all significantly higher than those in the control group,and L1-NB angle was lower than that in the control group,the difference was statistically significant（P〈0.05）.In the research group,the scores of GI and PLI scores at the 16 thweek were significantly lower than those in the control group,the difference was statistically significant（P〈0.05）.Conclusion Compared with the traditional fixed appliance,the orthodontic treatment in bracketless appliance can better reduce the height of the posterior teeth,prevent the tilting of the front teeth in an excellent curative effect,and have more healthy mouth and gums.
