简要总结
EFFECT OF LOW LEVEL LASER THERAPY ON ORTHODONTIC MINISCREW DISPLACEMENT
详细描述
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.

结局指标
主要结局
effect of low level laser therapy on displacement of miniscrews
时间窗: 4 months
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
次要结局
- effect of LLL application on gingival condition around the miniscrew.(4 months)
