Conditions
Summary
study will be directed to evaluate silver-hydroxyapatite nano-coated versus uncoated orthodontic miniscrews for en masse retraction of the upper anterior segment.
Eligibility
Inclusion Criteria5
- Class I orthodontic cases with bimaxillary protrusion of the anterior segment of the upper jaw that need at least extraction for orthodontic treatment.
- Age 14-20 years.
- Good oral hygiene with healthy periodontium.
- Need for an absolute skeletal anchorage.
- Systemically healthy patients.
Exclusion Criteria5
- Patient with craniofacial anomalies (e.g, cleft lip and palate)
- Presence of systemic diseases or syndromes affecting bone metabolism (e.g, osteoporosis, rickets)
- Poor oral hygiene or uncooperative patients.
- Extensive dental caries or untreated periodontal disease.
- History of trauma or surgery affecting the maxilla or mandible.

Interventions
Patients will receive silver-hydroxyapatite nanocoated titanium miniscrews.These miniscrews will be placed in the maxillary bone for en masse retractonof the upper anterior teeth.
Patients will receive conventional uncoated titanium miniscrews of the same dimensions and design as the intervention of the group1, but without nano-coating.
