Study hypothesis
Recently a ligature free orthodontic bracket system has been introduced. It has been suggested that reduced friction associated with this system can provide considerable benefits to the patient, principally because the teeth align more rapidly. We propose to investigate the alignment rate of two fixed orthodontic vracked systems; Ormco Damon-2 self -ligating and Ormco Synthesis conventional siamese.
