Effects of Micro-osteoperforations on Lower Anterior Crowding Using Clear Aligners

patients with lower anterior crowding, after randomization and allocation, will receive intraoral scanning to create a digital model. using computer software, teeth segmentation, setup and stagging of tooth movement will be carried out. models for each stage of tooth movement will be three-dimentionally printed and the aligners will be thermoformed over each model. patients are instructed to wear each aligner for a week then continue to the next aligner till treatment is finished

patients having lower anteriro crowding, after randomization and allocation, aligners will be produced for them. patients in this group will receive micro-osteoperforation using mini-implants before wearing the first aligner and after one month from starting treatment.
