About this study

Official title: Evaluation of Orthodontic Extrusion of Impacted Mandibular Third Molar in Close Proximity to Inferior Alveolar Nerve Prior to Extraction ( a Clinical Trial)

The goal of this clinical trial is to investigate the usage of maxillary miniscrew and cross-arch elastics for the orthodontic traction of the impacted mandibular third molar in close proximity to the inferior alveolar nerve to decrease the chance of nerve injury

Read the detailed description

To investigate the traction of the impacted mandibular third molar away from the inferior alveolar nerve by using the orthodontic miniscrew in the maxillary bone and cross-arch elastic power chain as a temporary anchorage device before extraction to avoid injury of the nerve and neurosensory complications.

Being tested

What is being measured

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

  1. Radiographically

    By measuring the amount of extrusion of the impacted tooth gained in millimetres Using CBCT

    Measured: 6months

Secondary outcomes (3)
  1. Clinical neurosensory assessment

    By using pinprick test in which ;A sharp dental probe was applied to the skin over chin region, lip and mucosa in a quick pricking movement and pain perception of the patient was assessed. Each area was tested three times bilaterally.the scale ranged from 0-2, where 0= no sensation, 1= decreased sensation and 2= normal sensation.

    Measured: 6months

  2. clinical brush stroke directional test

    using a micro brush tip which was moved in horizontal and/or vertical directions on the chin area ten times and asked the patient to reproduce the movements the scale ranged from 0-2, where 0= no sensation, 1= decreased sensation and 2= normal sensation.

    Measured: 6months

  3. Clinical Two-point discrimination test

    By using probes of caliper device which were drawn across the skin at constant pressure and patient was asked whether one or two points were felt, the minimum separation distance was felt by the patient was termed two point discrimination threshold.scoring from 0-2 in which; 0=>15mm, 1=8-15, 2= <8 .

    Measured: 6months

Questions about this trial

What is this clinical trial studying?

A study testing Orthodontic extrusion of the impacted mandibular third molar by using the maxillary miniscrew and cross arch elastic power chain as a temporary anchorage device before extraction in people with Inferior Alveolar Nerve Injuries, run by Alexandria University at 3 sites 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 3 inclusion and 3 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 27 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

Radiographically (time frame: 6months). 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 NCT06538688, which also lists 6 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 27 Aug 2024.
