EFFECT OF LOW LEVEL LASER THERAPY ON ORTHODONTIC MINISCREW DISPLACEMENT
Miniscrews can achieve good anchorage for different types of tooth movements, as intrusion, retraction, and protraction. However, obtaining primary stability is a challenge in their clinical application.Low Level Laser Therapy is suggested to prevent miniscrew displacement. Also previous studies concluded that Low Level Laser Therapy has an effect in stabilizing miniscrew after direct application. So the aim of this study is to assess the effect of Low Level Laser Therapy on displacement of miniscrews during canine retraction.

RECRUITINGeffect of low level laser therapy on displacement of miniscrews
Miniscrews displacement will be assessed after four months of canine retraction using CBCT scan. The head and tail of miniscrew will be measured in relation to anterior nasal spine as a fixed reference point before and after retraction
Time frame: 4 months
effect of LLL application on gingival condition around the miniscrew.
Gingival inflammation around miniscrew head will evaluated just after placement and at day 7 and 14 before application of retraction force and during days 21, 30, 60 which will be during the period of force application, based on modified gingival index with scores range from 0 to 3 as follows:Score 0 - no signs of inflammation (tissue around head is pink in color). Score 1 - mild inflammation (tissues are red in color, no bleeding sign). Score 2 - moderate inflammation (tissues are intense red in color, small bleeding signs). Score 3- severe inflammation (bleeding, evidence of swelling).
Time frame: 4 months
