About this study

Official title: Evaluation of Two Approaches of Micro-osteoperforations During Orthodontic:A Prospective Clinical Study

The aim of this clinical prospective study will be directed to evaluate two approaches of micro-osteoperforations (MOPs) during orthodontic canine retraction.

Read the detailed description

The aim of the present clinical study was directed to evaluate the effectiveness of two approaches of micro-osteoperforations (MOPs) during orthodontic canine retraction.

This study was conducted on a total sample of 36 canines of 18 patients, 15-22 years old who required therapeutic extraction of maxillary 1st premolars and canine retraction. They were selected randomly from the Outpatient Clinic, Department of Orthodontics, Faculty of Dental Medicine (Boys), Al-Azhar University, Cairo, Egypt.

they were randamly dived into two groups:as follows: Group I: include 9 patients , MOPs were performed for one time only on one side before retraction.

Group II: include 9 patients , MOPs were performed on repeated basis on one side.

Both maxillary canines, in each patient, were randomly assigned to either an experimental side or the control side in a simple split-mouth design. In the experimental side, micro-osteoperforations was performed distal to the maxillary canine at equal distance between maxillary canine and 2nd premolar before starting retraction, while the canines in the contralateral control side were retracted without micro-osteoperforations.

Extraction was done at the start of the treatment, and before fitting of the orthodontic appliance. Then upper dental arches were leveled and aligned using conventional sequences of wires.

Three flapless micro-osteoperforations was performed by using orthodontic miniscrews distal to the maxillary canines in the experimental side before starting retraction. Each perforation was 1.6 mm in diameter and 3-4 mm depth into the bone. Canines were completely retracted on 0.016 × 0.022 ̋ stainless steel wires by using closed coil spring delivered 150 gm force.

Patients were followed up every 28 days for 4 months of canine retraction. Routine orthodontic records were obtained for each patient before treatment.

Additionally, a full skull CBCT images were taken before treatment and immediately after canine retraction.

The rate of canine retraction was assessed clinically; in addition, cone beam CT (CBCT) scans were used to assess the amount of canine retraction root length changes. Also anchorage loss of first permanent molars were assessed.

The treatment results were compared clinically and radiographically (CBCT).

What is being measured

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

  1. Rate of canine retraction

    clinically, patients were evaluated immediately before canine retraction and every 28days until for months.

    It was based on measuring the distance between the contact points on the distal surface of the canines and the contact points on mesial surface of the second premolars.

    Measured: change from start of canine retraction until 4 months .

Questions about this trial

What is this clinical trial studying?

A study testing micro-osteoperforations in people with Bimaxillary Protrusion and Angle Class II, Division 1, run by Al-Azhar University at 1 site in Egypt.

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 0 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 16 Jun 2022. 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 Egypt. 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?

Rate of canine retraction (time frame: change from start of canine retraction until 4 months .). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Jun 2022.
