An interventional study of clear aligner treatment for orthodontics patients in Malocclusion, Angle Class I, sponsored by Future University in Egypt. Completed at 1 site in Egypt. Per ClinicalTrials.gov, last updated 2024-02-12.
Sponsored by Future University in Egypt · Not applicable, Interventional, and Treatment
14 Patients with mild to moderate crowding and spacing will be selected according to inclusion criteria.
Treatment planning will be done on Maestro® software. An impression will be taken and scanned by an extra-oral scanner. The models will be 3D printed and aligner trays will be fabricated to be delivered on biweekly basis to be worn 16 hours per day for one group and 22 hours for the other group. Superimposition of the achieved clinical model over the predicted model will be done. Linear and angular measurements will be calculated for each tooth.
Clear removable retainers could be related to clear aligners. Wearing time of retainers has been suggested that it could be changed from full time to part-time during the night only. A similar approach could be done to determine the effect of wearing time of clear aligners on treatment outcome. The standard duration per day for wearing the appliance is 22 hours. However, is part-time wearing (16 hours) would have the same effect? Therefore, a randomized clinical trial is needed to compare the effect of partial wearing of the aligner versus full time. Moreover, studying the predictability and accuracy of treatment using Maestro software.
Exclusion Criteria:
Patients will be instructed to wear the aligner for 16 hours per day, then the aligner going to be changed to the next step according to its numerical order in the software
Device: clear aligner treatment for orthodontics patients
Patients will be instructed to wear the aligner for 22 hours per day, then the aligner going to be changed to the next step according to its numerical order in the software
Device: clear aligner treatment for orthodontics patients
patient are instructed to wear aligners
Linear Movement Discrepancies Between Digital Software Models and Clinical Models
Translation movements (mm) were compared for each tooth between predicted models on Software predicted models and actual clinical models for the study groups
Time frame: an average of 1 year
Angular Movement Discrepancies Between Digital Software Models and Clinical Models
Translation movements (Degrees) were compared for each tooth between predicted models on Software predicted models and actual clinical models for the study groups
Time frame: an average of 1 year
Plan to share: Yes — The trial results will be available to the participants, health care professionals and the public by publication of the study in high quality national and international journals. The principal investigator will present a copy of the thesis at the Faculty of Oral and Dental Medicine, Future University in Egypt library and will distribute additional copies among the main universities in Egypt.
