简要总结
Patient with class ii division 1 malocclusion who have mild increased overjet will be treated in this study. The efficacy of clear aligners in the treatment of Class II division 1 Malocclusion Using Intermaxillary Elastics will be assessed. The skeletal, dental and soft tissues changes resulted by this intervention will be studied and compared with the results of Traditional treatment with fixed appliances.
There are two group:
- a group of patients in which participants will be undergo to the clear aligners with class ii elastics.
- a group of patients in which participants will be undergo to the traditional fixed appliances with class ii elastics.

结局指标
主要结局
change in ANB angle
时间窗: T0:1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group)
This angle the represents the spatial relationship between the upper and lower jaws in the cephalometric analysis in the anteroposterior direction. Lateral cephalograms will be taken and this angle is going to be measured in degrees.
change in the mandibular length [
时间窗: T0: 1day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group)
Amount of distance measured from the Co point to Gn point in the cephalometric analysis. Lateral cephalograms will be taken and this angle is going to be measured in degrees.
change in the SNB angle
时间窗: : T0:1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved(expected to be within 4-6 months in the exp. Group and 12 months in the control group)
This angle the represents the position of the lower jaw in the cephalometric analysis in the anteroposterior direction. Lateral cephalograms will be taken and this angle is going to be measured in degrees.
change in SN.PP angle [
时间窗: T0: 1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group)
This angle the represents the amount and direction of rotation of the upper jaw in the cephalometric analysis. Lateral cephalograms will be taken and this angle is going to be measured in degrees.
change in overbite
时间窗: T0: 1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group)
Amount of coverage the upper incisor to lower incisor in the vertical plane in the cephalometric analysis.
Change in the SNA angle
时间窗: : T0:1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group
This angle the represents the position of the upper jaw in the cephalometric analysis in the anteroposterior direction. Lateral cephalograms will be taken and this angle is going to be measured in degrees.
change in SN.POG angle
时间窗: : T0: 1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group)
This angle the represents the position of the chin bone in the cephalometric analysis in the anteroposterior direction. Lateral cephalograms will be taken and this angle is going to be measured in degrees.
change in MP.SN angle
时间窗: T0: 1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group)
This angle the represents the amount of backward rotation of the lower jaw in the cephalometric analysis. Lateral cephalograms will be taken and this angle is going to be measured in degrees.
change in overjet
时间窗: : T0: 1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 4-6 months in the exp. Group and 12 months in the control group)
Represents The distance between the most anterior point on the lower incisor to the most anterior point on the upper incisor in the cephalometric analysis.
