IRCT20210606051499N1 IRCT 2021-07-22 Mashhad University of Medical Sciences The uprighting of mandibular second molars in orthodontic patient A clinical trial to compare the effect of the miniscrew-supported technique with conventional techniques in mandibular second molar uprighting in patients under orthodontic treatment 2021-07-23 anticipated 10 Complete https://irct.ir/trial/56728 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, simple randomization will be used by random number table based on SAS (statistical analysis system), software. A list of sequentially number 1 to 10 will be created. This list will assign numbers randomly by computer. Patients are randomly assigned according to the numbers of this list. To conceal, we use Allocation concealment, using non-transparent envelopes sealed with random sequences (Sequentially numbered, sealed, opaque envelopes). They are placed in order. In order to maintain the random sequence, numbering is done on the outer surface of the envelopes in the same way. Finally, the lids of the envelopes are glued and placed inside a box, respectively. At the beginning of the registration of participants, based on the order of entry of eligible participants in the study, one of the envelopes will be opened in order and the assigned group of the participant will be revealed, Blinding description: The patients who refer to the Dental Clinic of Mashhad, Faculty of Dentistry, Mashhad, Iran, are selected as the participants of the study. In this single-blind study, sealed opaque envelopes will be used to conceal the sequencing. The person responsible for data collection is blind to the group allocation and the type of treatment. N/A Orthodontic. Intervention 1: Intervention group: The intervention group will receive miniscrew-supported approach for the uprighting of mandibular second molars. In this method, a mini-screw is placed in the distal second molar, and without the need for anterior teeth placement appliance, the molar operation is performed only with the help of the number one wire. Intervention 2: Control group: The control group will receive the conventional Melsen method for the uprighting of mandibular second molars. In this method, a mini-screw is placed between the seventh and fifth teeth, and the apparatus is performed with the help of one spring, and the extraction is prevented with the help of the second wire. Yes - There is a plan to make this available What will be shared: The information obtained from the main outcomes of the study can be shared When: 6 months after publishing the results To whom: The research data is exclusively accessible to the researchers working at universities and centers for scientific research Conditions: The research data is exclusively accessible to the researchers working at universities and centers for scientific research Where to obtain: Mostafa Entezari provides the data analysis to the applicants via email: mostafa.entezari91@gmail.com How to obtain: Applicants can send emails to him and receive a response within a week.
