Evaluation of the Rate of Maxillary En-masse Retraction Using 0.018-inch Versus 0.022-inch Slot Brackets in Adults
July 10, 2020 updated by: Omar Abdelaziz, Cairo University
Evaluation of the Rate of Maxillary En-masse Retraction Using 0.018-inch Versus 0.022-inch Slot Brackets in Adult Patients With Maxillary Dentoalveolar Protrusion: A Randomized Clinical Trial
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.
Study Overview
Status
Unknown
Conditions
Detailed 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.
