Treatments
Experimental: silver-hydroxyapatite nanocoated titanium miniscrews
Patients will receive silver-hydroxyapatite nanocoated titanium miniscrews. These miniscrews will be placed in the maxillary bone for en masse retraction of the upper anterior teeth.
Active_comparator: uncoated titanium miniscrews
Patients will receive conventional uncoated titanium miniscrews of the same dimensions and design as Arm 1, but without nano-coating.
