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.
- Conditions
- Malocclusion, Angle Class I, Crowded Teeth
- Being tested
- periodontally accelerated osteogenic orthodontics

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
periodontally accelerated osteogenic orthodonticsProcedure or surgery
Also called PAOO
Surgery will be performed to the lower anterior bony segment of the lower jaw in order to accelerate tooth movement
| Study group | Role | What they receive |
|---|---|---|
| Periodontally accelerated osteogenic orthodontics | Experimental | Patients in this group will undergo orthodontic treatment plus periodontally accelerated osteogenic orthodontics in order to induce tooth movement. Receives: Procedure: periodontally accelerated osteogenic orthodontics |
| Traditional orthodontics | No intervention | Patients in this group will undergo traditional orthodontics without any surgical interventions |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
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
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)
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
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
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
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
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
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

Questions about this trial
What is this clinical trial studying?
A study testing periodontally accelerated osteogenic orthodontics in people with Malocclusion, Angle Class I and Crowded Teeth, run by Damascus University at 1 site in Syria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Syria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2021.
