Evaluation of the Rate of Maxillary En-masse Retraction Using 0.018-inch

Status Not yet recruiting

Clinical Trial Summary

The study compares the rate of en-masse retraction using 0.018-inch versus 0.022-inch slot orthodontic bracket systems in adult patients with maxillary dentoalveolar protrusion.

Clinical Trial Description

- Proper examination of the oral structures is needed to identify caries, fracture or missing teeth.

- Full set of records ( study models, lateral cephalometric radiographs, photos) will be taken for every patient as part of the routine procedure for treatment of patients in the outpatient clinic of the Orthodontic Department, Cairo University.

- In intervention group: Bonding of upper and lower arches including 2nd maxillary molars with bracket prescription Roth 0.018-inch (American Orthodontics).

- In comparator group: Bonding of upper and lower arches including 2nd maxillary molars with bracket prescription Roth 0.022-inch (American Orthodontics).

- Levelling and alignment in both groups with wire sequence: Ni-Ti (0.014,0.016, 0.016×0.022)

- Steel ligation of maxillary (2nd premolar, 1st molar and 2nd molar) for anchorage.

- Extraction of maxillary 1st premolars.

- Impression will be taken, poured in plaster from which digital models will be fabricated before beginning of en-masse retraction (the baseline model).

- Lateral cephalometric and periapical radiographs will be taken before starting retraction.

- En-masse retraction will be done using 0.017x0.025 TMA T-Loop10 in both groups, the loops will be reactivated monthly.

- Alginate impressions will be taken every month, that will be scanned to obtain digital models to assess the rate of retraction for 6 months.

- After 6 months, last obtained digital model will be evaluated for assessment of anchorage loss, and Lateral cephalometric and periapical radiographs will be taken to assess changes in the anterior teeth inclinations and apical root resorption respectively.

- The patients' treatment will be completed as indicated for them. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
