Assessment of Low Level Laser Therapy Effect on Treatment Outcomes of Bony Supported Distal Jet for Correction of Angle Class II Malocclusion (Randomized Clinical Trial)

Study Overview
=================
Brief Summary
-----------------
The goal of this randomized clinical trial is to compare the effect of LLLT in adolescent patient with class II malocclusion. The main question it aims to answer is: • is there a difference in the amount of distalization between laser and control groups? Participants will received bony supported distal jet. Researchers will compare laser group with control group to see if there is a difference in amount of distalization between groups.

Detailed Description
-----------------
The aim of the present study is to assess the effect of low level laser therapy on treatment outcomes of bony supported distal jet for correction of 20 orthodontic patients with angle class II malocclusion. enrolled patient is randomly divided into 2 groups laser group and distal screw group. for result assessment dental casts and CBCT are taken before and after completion of distalization. both groups receives Distal Jet supported on 2 paramedian screw with laser therapy for laser group only.
