简要总结
The study is a single blind randomised control trial.The patients will be randomly assigned to have conventional brackets placed or self ligating brackets placed.
All patients will undergo full Orthodontic records. This will include an Orthodontic assesment, study models relevant xrays (orthopantogram and a cephalomgram) and clinical photos. 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.
These patients will be recalled at monthly intervals for the duration of treatment time which will be 3 years. A cephalogram will be taken at the end of treatment
