Detailed Description

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

What is the effect of the different treatment modalities (distalization versus upper premolar extraction) of class II malocclusion on the position, inclination and incidence of impaction of the upper third molars? Pico P: Adolescent patients with class II malocclusion having bilateral developing upper third molars.

I: bilateral upper first premolar extraction orthodontic treatment with moderate anchorage.

C: distalization orthodontic treatment. O: Primary: angulation of the maxillary third molars.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adolescent males and females (16 -18 years) with Bilaterally developing maxillary third molars. Not more than two thirds of the root development of the third molars had taken place.
* Class II malocclusion cases that were treated by 1) maxillary premolar extraction with a moderate anchorage requirement and achieved full unit class II molar relationship or 2) Distalization treatment plan and class I molar relationship was achieved.
* Patients with high-quality pre- and post-treatment radiographs.
* Normal or increased vertical dimension.

Exclusion Criteria

* Maxillary Premolar extraction cases requiring maximum anchorage preparation.
* Low vertical dimension.
* Patients without dentofacial deformities, severe facial asymmetries, microdontia or hypodontia.
