【摘要】：目的比较自锁矫治器与传统结扎式矫治器用于拔牙矫治病例的矫治效率。方法从2006—2010年青岛大学医学院附属医院口腔正畸科就诊并完成治疗的错鉭畸形病例中选择使用Damon 3MX自锁矫治器(自锁组)与传统结扎式矫治器(结扎组)拔除4颗第一前磨牙病例各15例,分别记录其整平排齐时间、关闭拔牙间隙时间、总体治疗时间及有效复诊次数,并将数据进行统计学分析。结果整平排齐时间:自锁组为(5.8±2.10)个月,结扎组为(4.5±0.71)个月;关闭拔牙间隙时间:自锁组为(8.3±3.65)个月,结扎组为(6.6±2.99)个月;总体治疗时间:自锁组为(20.4±5.04)个月,结扎组为(16.8±2.66)个月;有效复诊次数:自锁组为(19.0±4.83)次,结扎组为(16.4±3.41)次。自锁组的整平排齐时间、关闭拔牙间隙时间、总体治疗时间及有效复诊次数均较结扎组多,但两组间差异均无统计学意义(P0.05)。结论在拔牙矫治中,Damon 3MX自锁矫治器并未表现出比传统结扎式矫治器更高的矫治效率。
[Abstract]:Objective to compare the efficiency of self-locking appliance and traditional ligation appliance in tooth extraction. Methods Damon 3MX self-locking appliance (self-locking group) and traditional ligation appliance (ligation group) were selected from orthodontic department of affiliated Hospital of Qingdao University Medical College from 2006 to 2010 to complete the treatment of tantalum malformation. Each of the 4 first premolars had 15 cases, The time of leveling, closing the extraction space, the total treatment time and the number of effective revisits were recorded, and the data were analyzed statistically. Results the time of alignment was (5.8 卤2.10) months in self-locking group, (4.5 卤0.71) months in ligation group, (8.3 卤3.65) months in self-locking group and (6.6 卤2.99) months in ligation group, and (20.4 卤5.04) months in self-locking group and (16.8 卤2.66) months in ligation group. The number of effective revisits was (19.0 卤4.83) times in the self-locking group and (16.4 卤3.41) times in the ligation group. In the self-locking group, the time of leveling, closing the extraction space, the total treatment time and the number of effective revisits were more than those in the ligation group, but there was no significant difference between the two groups (P0.05). Conclusion 3MX self-locking appliance is not more effective than the traditional ligation appliance in tooth extraction.
