3D Evaluation of Powerscope Appliance in Treatment of Skeletal Class 2 Malocclusion

Three-dimensional Evaluation of the Efficacy of Powerscope Appliance in Treatment of Skeletal Class 2 Malocclusion: A Prospective Clinical Study

The study is aiming to evaluate the efficacy of Powerscope appliance in treatment of skeletal Class 2 malocclusion by three-dimensional image. Powerscope appliance is a hybrid fixed functional appliance used for treatment of Class II malocclusion with a retruded mandible.

Inclusion Criteria:

1. Healthy post pubertal female patients of age range 14 to 16 years old, manifesting features of post pubertal cervical vertebrae maturational stages 4, 5 and 6 (deceleration, maturation, and completion).
2. Skeletal class 2 malocclusion of ANB angle greater than 4° with retrognathic mandible.
3. Class II division 1 malocclusion with at least an end-on Class II molar relationship.
4. Presence of all permanent dentition excluding third molars.
5. Good oral hygiene.

Exclusion Criteria:

1. History of previous orthodontic treatment.
2. Any systemic disease that could affect the orthodontic treatment.
3. Patients with periodontal diseases.
4. Patients with temporomandibular disorders.
