The author report a case of 14 year 3 months old female who presented to the orthodontic clinic with moderate upper and lower anterior crowding, proclination of upper anterior and increased overjet and overbite. It was decided to treat the case with non extraction orthodontic therapy using self ligating bracket system. Following 28 months of treatment time, there was a favorable outcome in the profile of the patient.
