this randomized controlled trial is designed to compare between clear aligner therapy in alleviating mandibular anterior crowding alone versus with micro-osteoperforations

This study is carried on in order to provide a method to enhance the predictability of clear aligner treatment. Loss of aligner tracking is one of the problems encountered during aligner treatment that results in increasing number of aligners required to complete treatment in addition to increasing the overall treatment time and cost. Micro-osteoperforation is a method for acceleration of orthodontic tooth movement and could be used to improve tooth movement and predictability of treatment with clear aligners. So this study is aimed to evaluate the efficiency of aligner treatment during alleviation of lower anterior crowding with and without micro-osteoperforations
