用自锁托槽与传统MBT直丝弓对牙列拥挤患者进行正畸治疗的效果对比

Comparison of orthodontic treatment effect between self-locking socket and traditional MBT straight wire arch for crowded patients

目的 :比较用自锁托槽与传统MBT直丝弓对牙列拥挤患者进行正畸治疗的效果。方法 :选取2015年1月至2017年1月期间绵竹市人民医院收治的65例牙列拥挤患者作为研究对象。根据治疗方法的不同将这些患者分为观察组(n=33)和对照组(n=32)。为观察组患者使用自锁托槽进行正畸治疗,为对照组患者使用传统的MBT直丝弓进行正畸治疗。然后比较两组患者治疗的效果。结果 :治疗后,观察组患者复诊的次数少于对照组患者(P <0.05),其牙弓宽度的增加量及前磨牙间宽度、上前牙凸度均大于对照组患者(P <0.05),其总疗程、排齐牙列的时间、接受椅旁操作的时间均短于对照组患者(P <0.05)。两组患者的第一磨牙间宽度、尖牙间宽度相比,P>0.05。结论 :与用传统MBT直丝弓对牙列拥挤患者进行正畸治疗的效果相比,用自锁托槽对其进行正畸治疗的效果更为理想。

objective: to compare the orthodontic effects of self-locking socket and traditional MBT straight wire arch in the treatment of crowded patients with dentition. Methods: 65 patients with dental crowding admitted to mianzhu people’s hospital from January 2015 to January 2017 were selected as the research objects. These patients were divided into observation group (n=33) and control group (n=32) according to different treatment methods. In the observation group, self-locking socket was used for orthodontic treatment, while in the control group, traditional MBT straight wire arch was used for orthodontic treatment. And then compare the therapeutic effects between the two groups. Results: after treatment, the observation group of patients return the number of times less than the control group patients (P < 0.05), the increase of width of dental arch and premolars crown width, forward between teeth were greater than the control group patients (P < 0.05), the total treatment time, aligned teeth, accept the chair beside the operating time is shorter than the control group patients (P < 0.05). The intermolar width and intercanine width of the two groups were compared, P > 0.05. Conclusion: compared with the traditional MBT straight wire arch for orthodontic treatment of crowded patients, self-locking socket is more effective.
