The current study was directed to evaluate rate of oseointegration surrounding nano-coated orthodontic titanium miniscrew.The current study will conduct on eighteen Egyptian males orthodontic patients for three months. Study Groups: A- Blank group: include six orthodontic patients, which have a surgical procedure to install two orthodontic titanium miniscrews in the two lateral parts of the maxilla , so this group will include 12 installed orthodontic titanium miniscrews. B- Silver hydroxyapatite group: include six orthodontic patients, which have a surgical procedure to install two silver hydroxyapatite nano-coated orthodontic titanium miniscrews in the two lateral parts of the maxilla, so this group will include 12 installed silver hydroxyapatite nano-coated orthodontic titanium miniscrews. C- Zinc oxide group: include six orthodontic patients, which have a surgical procedure to install two zinc oxide nano-coated orthodontic titanium miniscrews in the two lateral parts of the maxilla, so this group will include 12 installed zinc oxide nano-coated orthodontic titanium miniscrews.
