DISCUSSION
RAP, tooth
Due to the lack of sufficient data on the long-term influence of L-PRF on the rate of
canine movement,Immediately after careful extraction of first premolars, L-PRF plugs were inserted
into the extraction socket to trigger regional acceleratory phenomenon (RAP). The
experimental side of the trial, where the L-PRF plugs were inserted, displayed a
higher rate of canine retraction than the control side, which was temporary only for
the first two months. The findings of the present study are in accordance with
previous studies.In the present study, all measurements were taken from the third palatal rugae, which
is considered as stable structure.During tooth movement, force application away from the center of resistance results
in unwanted tipping and rotation. There were no appreciable differences between
groups regarding canine rotation or inclination. These findings are consistent with
those from other studies.
