Assessment of Coated Orthodontic Miniscrews With Chlorhexidine Hexametaphosphate Antimicrobial Nanoparticles

"insertion:~1. According to the random number generated, the corresponding envelop for left and right side by chosen.~2. The patient will be asked to brush his/her teeth.~3. The patient will rinse his/her mouth with chlorhexidine mouth rinse (0.12%) just before surgery being at least half an hour after brushing.~The miniscrews used conical shaped, self-drilling, 1.6 mm in diameter, 8mm in length made of Ti.~1. The site of insertion determined from the x-ray by using stent that will be fabricated for accurate site for OMS.~2. Infiltration LA will be administered. Approximately 0.45 mL ,injected into the alveolar mucosa above the OMS placement site, in order to provides an acceptable anesthesia, while still allowing the patient feedback in case the OMS contacting the periodontal ligament (PDL).~3. OMS will be placed manually by screw driver on buccally at an angle 90 degrees and then adjusted to the appropriate angle.~4. x-ray will be taken to confirm OMS position."
