ABSTRACT
Abstract:

Aim: The Study Was Conducted To Provide A Three Dimensional Evaluation Of The Synergistic Effect Resulting From Combined Low Energy Laser Application And Micro-Osteoperforations On The Maxillary Canine Retraction In Orthodontic Patients. Patients And Methods: Three Parallel Groups (each Group Contained 10 Patients) Were Performed; Group A: Split Mouth Study Design In Which One Side Was Control Side And The Other Side Received Micro-osteoperforations (MOPs), Group B: Split Mouth Study Design In Which One Side Was Control Side And The Other Side Received Low Level Laser Therapy (LLLT), Group C: Split Mouth Study Design In Which One Side Was Control Side And The Other Side Received Both MOPs And LLLT. All Patients Were Radiographed By CBCT Images Before And After Canine Retraction And DDS-Pro Soft-ware Was Used For Evaluation Of The Maxillary Canine Retraction.

Results: Significant Statistical Differences Were Obvious In The Rate Of Canine Retraction Between Each Intervention And The Control Sides As Follow; The Mean Distance Travelled By The Canine Cusp Tip Point Relative To The Frontal Plane In Three Months In The Control Group Was 2.25 Mm�1.46 Mm, In The MOPs Group Was 3.86 Mm�1.56 Mm, In The LLLT Group Was 3.55 Mm�1.63 And In The Combined MOPs& LLLT Group Was 4.81 Mm�1.56 Mm. Conclusion: MOPs Technique Has The Ability To Accelerate The Rate Of Canine Retraction More Than The Application Of LLLT As Compared To The Standard Canine Retraction Technique. Moreover: Combination Of MOPs And LLLT Proved To Be More Efficient Regarding Increasing The Rate Of Canine Retraction Than The Application Of Each Technique Separately.
