IRCT20171220037973N1 IRCT 2018-10-11 Mashhad University of Medical Sciences Effect of micro-osteoperforation on rate of tooth movement. The effect of micro-osteoperforation on the rate of orthodontic tooth movement. A randomized clinical trial 2018-09-18 anticipated 48 Complete https://irct.ir/trial/33846 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: A five digit number would be allocated to each patient and after simple randomization using a statical software, allocation concealment would be done using opaque white envelopes. N/A Orthodontic tooth movement. Intervention 1: Intervention group: Three micro-osteoperforations will be made on the distal of the left and right canines using a miniscrew (self-threading (1.2x6 mm Jeil, Korea)). The perforations will be 2 mm apart and will have at least a 5mm depth. The process will be done under local anesthesia (lidocaine with 1:100,000 epinephrine 2%). The location for MOP and their distance from each other will be measured using a periodontic probe. If there is any discomfort, the patient is advised to take acetaminophen for pain management. Then the canines will be retracted using a 150g Ni-Ti close spring between canine and first upper molars' hooks. The MOPs will be repeated at 4 and 8 weeks later and the tooth movement will be measured at every 2 weeks. Intervention 2: Control group: Canines of these patients will be retracted using a 150g Ni-Ti close spring which will be placed between canine's hook and the first molars' tube on a 19X25 stainless steel arch wire. Yes - There is a plan to make this available What will be shared: Only primary outcome measures will be shared. When: About 1 year after the data summary have been published. To whom: Everybody who makes an inquiry, regardless of academic or business employees. Conditions: The data for use in systematic reviews and meta-analyses, after assessment by Erfan Bardideh will be made available.

Canine tooth movement in relation to first molar. Timepoint: Right before retraction and 2, 4, 6, 8, 10 and 12 weeks after retraction. Method of measurement: Using a digital caliper with 0.2 mm accuracy the distance between the tip of canine and the mesiobuccal cusp of the first molar and also the distal of the canine bracket and mesial of the molar tube will be measured.
