| 目的 比较国产3B 自锁托槽、Damon Q 自锁托槽以及国产3B 直丝弓托槽的椅旁操作时间, 为国产3B 自锁托槽的临床应用提供参考依据。方法 选择正畸患者80 例, 其中20 人使用国产3B 自锁托槽(3B 自锁组), 20 人使用Damon Q 自锁托槽(Damon Q 自锁组), 20 人使用国产3B 直丝弓托槽+ 结扎丝结扎(结扎丝组), 20 人使用国产3B 直丝弓托槽+ 橡皮圈结扎(橡皮圈组)。待患者上下颌牙列基本排齐后, 使用0.018*0.025 英寸镍钛方丝入槽, 记录全口结扎和拆除时间。采用单因素方差分析, 比较4 组患者的结扎和拆除时间。结果 3B 自锁组的结扎、拆除和总时间均明显短于结扎丝组和橡皮圈组(P<0.01)。3B 自锁组和Damon Q 自锁组在结扎、拆除和总时间方面的差异均无统计学意义(P>0.05)。结论 无论是采用结扎丝结扎还是橡皮圈结扎, 国产3B 自锁托槽的椅旁操作时间明显短于直丝弓托槽, 且与进口的Damon Q 自锁托槽相比无明显统计学差异。 |

| Objective To compare the chairside time among domestic 3B, Damon Q self-ligating and 3B straight wire brackets. Methods 80 orthodontic patients were enrolled in the study. 20 patients were treated with domestic 3B self-ligating brackets, 20 patients with Damon Q self-ligating brackets, 20 patients with straight wire brackets ligated by ligature wires, and 20 patients straight wire brackets ligated by elastomeric rings. After aligning the maxillary and mandibular dentitions, a NiTi rectangular arch wire of 0.018*0.025 inch was inserted into the brackets, and the time of ligation and deligation was recorded. One-way ANOVA was used to compare the chairside time of archwire ligation and deligation for the four groups. Result The ligation, deligation and total time of 3B self-ligating bracket group was significantly less than that of ligature wire group and elastomeric ring group (P<0.01). However, there was no significant difference in the ligation, deligation and total time between domestic 3B and Damon Q self-ligating brackets (P>0.05). Conclusions The chairside time of 3B self-ligating bracket group was significantly less than that of ligature wire group and elastomeric ring group, but closed to the Damon Q self-ligating bracket group. |
