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

Summary

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

Detailed description

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

Conditions

• Mandibular Dental Crowding

Interventions

Type	Name	Description
DEVICE	clear aligners group	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
DEVICE	micro-osteoperforations group	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.
