ClinConnect Summary

This clinical trial is studying two different methods for moving teeth in post-pubertal girls who need orthodontic treatment. Specifically, it compares the effectiveness of using arch wire stoppers versus mini-screws to control how well the teeth stay in place while the canine teeth (the pointy teeth next to the front ones) are retracted or moved back. The goal is to find out which method works better for patients who have a certain type of bite problem that requires the removal of some teeth.

To participate in this study, candidates must be post-pubertal females with specific dental conditions, such as bimaxillary protrusion (where the upper and lower teeth stick out) or a Class II Division 1 malocclusion (a type of bite misalignment). They should have all their permanent teeth except for the third molars (wisdom teeth) and maintain good oral hygiene. Unfortunately, individuals with certain medical conditions, a history of orthodontic treatment, or harmful dental habits are not eligible. If you qualify, you can expect to be part of a study that aims to improve orthodontic treatment outcomes.

Eligibility criteria

• Inclusion Criteria:
• • Post-pubertal female patients.
• • Cases with bimaxillary protrusion or Class II Division 1 malocclusion that require maxillary first premolars extraction.
• • Full permanent dentition (not necessitating third molars).
• • Good oral hygiene.
• Exclusion Criteria:
• • Medically compromised patients.
• • Active periodontal disease or obvious bone loss in the maxillary arch.
• • Patients with habits that are detrimental to dental occlusion (thumb sucking, tongue thrusting).
• • Smoking or any systemic diseases.
• • Chronic use of any medications including antibiotics, phenytoin, cyclosporine, anti-inflammatory drugs, systemic corticosteroids, and calcium channel blockers. All the above factors affect the rate of tooth movement
• • Previous orthodontic treatment.
• • Missing teeth.
