Not Applicable

Not yet recruiting

• Conditions: Skeletal Malocclusion
• Interventions: Other: orthopedic appliance; Other: aesthetic orthopedic appliance

• Registration Number: NCT06631235
• Lead Sponsor: Mansoura University

Brief Summary

The goal of this is to evaluate the skeletal, dental and soft tissue effects between aesthetic functional appliance and Twin block appliance in treatment of skeletal class II in ( growing male/female patients)

Detailed Description

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 .
