After records analysis, patients will be given a prophylaxis and oral hygiene instructions. Either 3m Victory Series™ Metal Braces or 3m SmartClip™ SL3 Self-Ligating Braces both bracket types will carry the MBT prescription 0.022 slot height, will be bonded using Transbond™ XT (3M Unitek, Monrovia, California, USA) composite resin according to the manufactuer's instruction.
