Evaluation of Self-ligating Brackets Plus Minor Surgery in Treating Crowded Cases of Malocclusion
Condition: Malocclusion of Anterior Teeth
MeSH terms: Malocclusion
Study type: Interventional

Summary: 
      Patients at the Orthodontic Department of University of Damascus Dental School will be
      examined and subjects who meet the inclusion criteria will be admitted then the initial
      diagnostic records (diagnostic gypsum samples - internal and external oral photographs as
      well as radiographic images) will be studied to ensure that the selection criteria are
      accurately matched.

      The aim of this study is to compare three groups of patients with severe crowding of the
      upper anterior teeth:

        -  Group 1 : Patients will be treated using self-ligating brackets

        -  Group 2 : Patients will be treated using self-ligating brackets associated with flapless
           corticotomy.

        -  Group 3 : Patients will be treated using traditional brackets (i.e. brackets positioned
           on the labial surface of the teeth)

      At the end of leveling and aligning phase, we will compare the self-ligating brackets and
      traditional brackets ( the acceleration of teeth movement, dental and alveolar changes and
      other variables ) Also, there is an intention to study the effectiveness of using flapless
      corticotomy with the self-ligating brackets.
    

Detailed description: 
      The sample of this study will be chosen according the following steps:

        -  The examination of patients referred to the Department of Orthodontics at the University
           of Damascus Dental School (clinical examination, diagnostic plaster models, radiographic
           photos , external and internal oral photographs) then subjects who meet the inclusion
           criteria will be included in this trial.

        -  A random sample of 100 patients from the sampling frame will be chosen.

        -  An information sheet ( including the research objective and treatment plan in detail )
           will be given to each candidate. Then consent forms will be collected from those who
           agree to participate.

        -  A random selection of 60 patients will be performed. Then a random distribution of these
           patients to 3 groups will be done.
    

Intervention name(s): Self-Ligating Brackets; Traditionally-Ligated Brackets; Corticotomy
Intervention type(s): Device; Device; Procedure
Intervention description(s): These brackets can be opened and closed through the use of a sliding cap embedded into the design of these brackets. There is no need to use elastic modules to ligate the arch.; These brackets are used in the conventional manner, where the orthodontist is obliged to use elastic modules to engage the arch into the slot of the bracket.; Corticotomy without flap elevations will be performed in order to induce acceleration in tooth movement during the orthodontic treatment in only one group.
Other intervention name(s): SLBs; Non-SLBs; Piezosurgery; Decortication
Allocation: Randomized
Intervention model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary purpose: Treatment
