in the study, investigators tried to evaluate two methods to accelerate tooth movement by comparing them with control group. the first method was to apply one-time micro-osteoperforation. the second method was to apply the micro-osteoperforation repeatedly till reaching the end of the phase one treatment.
the study aimed to evaluate the effect of different types of Micro-osteoperforation on the rate of distal movement of maxillary first molars as a primary out come. Besides, it was aimed to study secondary effect on the first molars by evaluating root resorption, bone density, and level of the pain during performing the procedures.
