About this study

Official title: Evaluation of the Efficacy of Periodontally Accelerated Osteogenic Orthodontics in the Leveling and Alignment of Crowded Lower Anterior Teeth: A Two-Arm Randomized Controlled Clinical Trial

Patients at the Orthodontic Department of University of Damascus Dental School will be examined and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, 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 two groups of patients with moderate crowding of the lower anterior teeth First group (Experimental): the patients in this group will be treated with orthodontic fixed appliances + surgery to the alveolus of the lower anterior teeth in order to induce remodeling of the bony structures and enhance orthodontic movement.

Second group (Control): the patients in this group will be treated using fixed appliances with any acceleration method.

Being tested

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Duration of Alignment

    The time required in days will be calculated from the beginning of treatment till the end of the alignment stage

    Measured: The assessment is based on calculating days from the beginning of treatment till the end of the alignment stage which is expected to happen within 5 to 6 months

  2. Change in Little's Index of Irregularity

    The irregularity of the lower incisors is calculated by measuring the amount of deviations of the anatomic contact points between the six anterior teeth in the horizontal direction in mm, since the sum of these measurements represents the value of the index (Little, 1975). When the sum of these deviations is less than 3 mm, this indicates that the teeth are slightly crowded. When the sum is greater than 10 mm, this indicated very severe crowding.

    The ordinary orthodontic treatment aims to keep this Index less than 1 mm at the end of treatment.

    Measured: T0: one day before the beginning of treatment; T1: after 1 month; T2: after 2 months; T3: after 4 months; T4: after 5 months; T5: at the end of the alignment stage which is expected within 5 - 6 months

  3. Change in Alveolar Defect

    Using cone-beam computed tomography (CBCT), each tooth root will be evaluated in axial and cross-sectional slices at the buccal and lingual surfaces. When no cortical bone is observed around the root in at least three sequential views, this will be considered an alveolar defect. If the alveolar bone height is more than 2 mm from the cemento-enamel junction, it will be classified as dehiscence ,When the defect does not involve the alveolar crest, this case will be classified as fenestration.

    The status of the alveolar bone will be assessed twice.

    Measured: T1: One day before the beginning of treatment; T2: at the end of the alignment stage which is expected within 5-6 months

Secondary outcomes (6)
  1. Change in inter-canine width

    The distance between the cusp tips of the lower canines. This variable will be measured on plaster models.

    T1: One day before the beginning of treatment; T2: at the end of the alignment stage

    Measured: T1: One day before the beginning of treatment; T2: at the end of the alignment stage which is expected within 5-6 months

  2. Change in Alveolar Bone Thickness

    Will be measured for each of the lower anterior teeth in the cervical, middle, and apical regions. This will be achieved by using the ruler which will be positioned perpendicular to tooth long axis from the root surface (without measuring the periodontal ligament ) to the most external surface of the cortical bone.

    Measured: T1: One day before the beginning of treatment; T2: at the end of the alignment stage which is expected within 5-6 months

  3. Change in Lower Incisors' Inclination

    The angle between the long axis of the lower Incisors and the mandible plane (Go-Me) will be measured.

    Measured: T1: One day before the beginning of treatment; T2: at the end of the alignment stage which is expected within 5-6 months

  4. Change in the positioning of the upper lip

    It is going to be evaluated by Ricketts' analysis (E-Line). This is done by drawing a reference line between the tip of the nose and the most prominent point on the chin contour (Pogonion).

    The distance of the upper lip from this line is a measure of lip positioning.

    Measured: T1: One day before the beginning of treatment; T2: at the end of the alignment stage which is expected within 5-6 months

  5. Change in the positioning of the lower lip

    It is going to be evaluated by Ricketts' analysis (E-Line). This is done by drawing a reference line between the tip of the nose and the most prominent point on the chin contour (Pogonion).

    The distance of the lower lip from this line is a measure of lower lip positioning.

    Measured: T1: One day before the beginning of treatment; T2: at the end of the alignment stage which is expected within 5-6 months

  6. Change in the naso-labial angle

    It is the angle formed between the lower border of the nose and the upper lip.

    Measured: T1: One day before the beginning of treatment; T2: at the end of the alignment stage which is expected within 5-6 months

What does the primary outcome measure?

Duration of Alignment (time frame: The assessment is based on calculating days from the beginning of treatment till the end of the alignment stage which is expected to happen within 5 to 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03659097, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
