About this trial

Patients with skeletal class II malocclusion who have a retracted lower jaw will be treated in this study. The efficacy of clear Plates in the treatment of Skeletal Class II Malocclusion 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.

Trial outcomes

Primary outcomes

1

Change in the SNA angle[

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.

Time frame
: T0:1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 6-9 months in the exp. Group and control group)
2

change in the SNB angle [

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.

Time frame
: T0:1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 6-9 months in the exp. Group and control group)
3

change in the mandibular length

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.

Time frame
T0: 1day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 6-9 months in the exp. Group and control group)
4

change in overjet

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.

Time frame
T0: 1 day before the beginning of treatment . T1: when a normal overjet and canines class I relationships achieved (expected to be within 6-9 months in the exp. Group and control group)
