目的：比较口腔牙齿矫正中不同材料矫正器的应用效果。方法选择2014年7月至2015年7月采用牙齿矫正器行口腔牙齿矫正的180例患者，将其随机分为两组。观察组采用不锈钢结扎丝行固定治疗，对照组采用弹力结扎圈行固定治疗，比较两组疗效。结果观察组中总有效率显著高于对照组，差异有统计学意义（P <0.05）；观察组结扎时间为（294.2±4.2）s，拆除时间为（53.5±4.5）s；对照组结扎时间为（188.5±4.1）s，拆除时间为（39.6±5.0）s，两组比较差异有统计学意义（P <0.05）。结论采用不锈钢结扎丝矫正器进行口腔牙齿矫正，所需时间较长，疗效确切，在临床实际应用时需要综合考虑选择合适材料进行治疗。“,”Objective To investigate the application effect of different material dental braces on dental orthodontics. Methods A total of 180 patients whose teeth were corrected by dental braces from July 2014 to July 2015 were selected and were randomly divided into two groups. Patients in the observation group were treated by stainless steel ligature wire for fixation while patients in the control group were treated by elastic ligature ring for fixation,and then the clinical effects between the two groups were compared. Results The total efficiency in the observation group was significantly higher than that in the control group,there was significant difference(P < 0. 05). In the observation group,the ligation time was(294. 2 ± 4. 2)s and the re-moval time was(53. 5 ± 4. 5)s;while in the control group,the ligation time was(188. 5 ± 4. 1)s and the removal time was (39. 6 ± 5. 0)s. The clinical effect in the observation group was significantly higher than that in the control group(P < 0. 05). Conclusion The use of stainless steel ligature wire for orthodontic treatment needs a longer time,but the clinical effect is per-fect. So in clinical practice,it is necessary to consider the choice of suitable materials for treatment.
