| 目的 研究传动直丝弓矫治器和MBT直丝弓矫治器对安氏Ⅱ类错牙合患者头影测量项目水平的影响。方法选择接受治疗的安氏Ⅱ类1分类深覆牙合患者34例。分别用采用MBT直丝弓矫治器(MBT组)和传动直丝弓矫治器(传动组)进行治疗,每组各17例。比较两组患者的头影测量项目和软组织水平。结果两组在头影测量项目角度和线距,以及软组织变化方面,在治疗前后均存在不同程度差异,但传动组较MBT组更显著；两组治疗后平均咬合打开时间,传动直丝弓组(4.12±0.48)月小于MBT直丝弓组(7.18±0.57)月(P<0.05)。结论传动直丝弓矫治器可以快速打开安氏Ⅱ类错牙合患者的咬合,同时可以内收上颌切牙解决前倾、深覆盖问题,改善患者软组织侧貌,但转矩的表达仍有不足。 |

| Objective To study the effect of transmission straight wire appliance and MBT straight wire appliance on the level of patients with malocclusion cephalometric class Ⅱ of the project.Methods34 cases of patients were randomly and evenly divided into MBT straight wire group(MBT)and drive straight wire group(DSW)(n=17),the MBT group was treated with MBT straight wire appliance,the DSW group was treated with the transmission straight wire appliance.The first shadow measurement project and the level of soft tissue between the two groups were compared.ResultsThe first shadow measurement project and the level of soft tissue between the two groups were different after or before treatment,but the curative effects of DSW group was superior to MBT group.The average occlusion time of DSW was short to MBT (4.12+0.48 vs 7.18+0.57) months (P<0.05).ConclusionThe transmission straight wire appliance can quickly open class Ⅱ malocclusion patients with occlusion,and can solve the maxillary incisor retraction forward,deep coverage problem,improve the soft tissue profile of patients,but the torque expression is still insufficient. |
