The aim of this study is to compare between the upper canine
retraction after corticotomy with laser and the upper canine
retraction using the standard treatment, and the patients'
acceptance to laser application.
Analysis of the rate of canine r
etraction between the laser
application and control sides shows significant differences during
the first and second months and no significant differences during
the third month. We also find that the patients' percentage that
accept laser application was bigger than the patients' percentage
that accept the extraction of first premolars.
