Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The sample will be randomly divided into 2 equal groups according to the appliance will be used:

Group 1: Aesthetic Functional appliance Group 2: Twin block

Methods:

\*Radiographs (CBCT) will be taken before starting the treatment (T1) and after obtaining Class I occlusion and normal overjet (T2) by sequential appliances.

appliances.

* Lateral cephalograms -extracted from CBCT- will be used to evaluate the effect of the two appliances.
* CBCT will be used to evaluate root resorption and bony changes in the condyle .
