Intervention code:

组别:

改良组

样本量:

20

Group:

modified group

Sample size:

干预措施:

改良组在传统矫治器的基础上,在前牙段每侧各设计生产一个附件空泡,临床上填充玻璃离子,嘱患者佩戴矫治器后咬实,直至获得咬合平衡。每个患者均佩戴6副不加力的被动矫治器,每副戴2周,每天戴22h。

干预措施代码:

None

Intervention:

In the modified group, two additional attachment cavities are added on lowrer anterior segment on the basis of conventional aligners,one on each quadrant, and are filled with glass ionomer cement to get occlusion equlibrium when the patient is instructed to bite tightly with aligners. Each patient wil wear 6 passive aligners, 2 weeks per aligner and 22h per day.
