Abstract

Facial asymmetry is extremely visible, has a negative impact on one's quality of life, and is a common orthodontic patient complaint. In order to improve the occlusion and facial aesthetics of patients with extreme facial asymmetry, a combination of orthodontic and orthognathic surgical procedures is typically used.
In Angle's Class II subdivision malocclusion, on one side, there is a Class I molar relationship, and on the other, a Class II molar relationship. It could be tied to oral problems, skeletal problems, or a mixture of both. In these circumstances, to have symmetry on each side and in each dental arche is the goal. More over half of all Class II cases are subdivision cases.
