Overview
Brief Summary
The aim of the current clinical trial was to evaluate the effects of premolar extractions compared with non-extraction orthodontic treatment on the skeletal vertical dimension of the face.
The null-hypothesis is that there is no difference in post-treatment skeletal vertical characteristics of normodivergent and hyperdivergent patients treated orthodontically with first premolar extractions compared with patients treated in non-extraction manner.
Detailed Description
The current protocol will be submitted for partial fulfillment of the PhD requirements in Faculty of Dentistry, Cairo University. The trial will be conducted in the outpatient clinic of the Orthodontic Department, Faculty of Dentistry, Cairo University. Primary examination and diagnosis of the patients seeking orthodontic treatment will be performed, to select a sample of the trial. then, final diagnosis and planing of each participant will be performed by a trained orthodontists to be sure that all patients fallen with the inclusion criteria. Interventions will be conducted with the same orthodontist, under supervision of orthodontic professors in the Orthodontic department, Cairo University.

Eligibility Criteria
Inclusion Criteria
- •Normodivergent and hyperdivergent patients
- •Cases with moderate crowding.
- •Borderline cases which could be treated with extraction or non-extraction strategies
Exclusion Criteria
- •Hypodivergent patients.
- •Cases with extremely sever crowding.
- •Patients with high caries index or periodontal problems.

Outcomes
Primary Outcomes
Changes in Vertical Dimension (VD)
Time Frame: after 1year. Changes will be measured before the start of trial and at the end of space closing stage, which anticipated to be within 12 months of intervention
Vertical dimension of the face will be assessed by measuring a distances in millimeters between vertical points as ANS-Me (lower facial height), also it will be measured form angles in a degrees as angle SN/MP
Secondary Outcomes
- Changes in Overbite(1 year . Changes will be measured before the start of trial and at the end of space closing stage, which anticipated to be within 12 months of intervention)
