About this study

Official title: Skeletal and Dentoalveolar Effects of Palatal Crib Versus Bonded Spurs in Early Treatment of Anterior Open Bite Caused by Non-nutritive Sucking Habits: A Randomised Clinical Trial.

The study evaluates the effects of palatal crib versus bonded spurs in the early treatment of anterior open bite caused by non-nutritive sucking habits.

Read the detailed description

Habit is an unintentionally performed repeated activity. Development of habit is considered a part of the natural progression of maturation in children between infancy and three years of age, after this period, it is assumed to be unnatural. The most familiar and earliest noted habit is thumb sucking. It develops during infancy as a rooting reflex, after it ceases around three years of age .

Thumb sucking is defined as the placement of the thumb or one or more fingers in different depths into the mouth ). It emerges in two forms: nutritive and non-nutritive, where the first gives nourishment and the second implements a sense of security and amenity. It is common in children and is reported to be harmless for up to five years of age .

There is an association between the habit of thumb sucking and the development of skeletal open-bite among children. Anterior open bites (AOBs) are defined as an occlusion in which the lower incisors are not overlapped in the vertical plane by the upper incisors and do not occlude with them when the posterior teeth are in maximum intercuspation . Anterior open bite due to thumb sucking, and a secondary tongue thrust exaggerates the condition . If identified early, this can be avoided and appropriate treatment is delivered.

Approaches for habit intervention include counseling, positive reinforcement, a calendar with rewards, an adhesive bandage, bitter nail polish, long sleeves, and appliance therapy. It is recommended to start with the least invasive methods before using habit-breaking appliances. Habit-breaking appliances are either fixed or removable. Fixed appliance therapy may be considered after the age of 4 years. Appliances consisting of cribs in the anterior region are very efficient as reminders and physical restrainers . The palatal crib works as an obstacle in non-nutritive sucking and maintains the tongue in a more retruded position, halting its interposition between the incisors. Spur appliances change tongue action, close the open bite, and boost treatment stability, as it induces a permanent modification of the tongue's anterior rest posture by altering orofacial function, resulting in a change in form. Finally, the spur adjusts the sensory input to the brain. This proprioceptive change leads to an altered motor response, resulting in a new normal tongue rest posture (change in function) that allows the incisors to erupt.

Being tested
Palatal Crib, bonded spur

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Palatal CribDevice

    An intraoral appliance approach can be used as an adjunct method to stop the habit. Appliances consisting of cribs in the anterior region are very efficient as reminders and physical restrainers. The palatal crib works as an obstacle in non-nutritive sucking and maintains the tongue in a more retruded position, halting its interposition between the incisors.

  • bonded spurDevice

    Spur appliances change tongue action, close the open bite, and boost treatment stability, as it induces a permanent modification of the tongue's anterior rest posture by altering orofacial function, resulting in a change in form. Finally, the spur adjusts the sensory input to the brain. This proprioceptive change leads to an altered motor response, resulting in a new normal tongue rest posture (change in function) that allows the incisors to erupt

What is being measured

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

  1. Overbite distance correction in millimeter

    Digital dental model will be scanned using medit software to detect the changes that occur in the vertical distance ( in millimeter ) between incisal edges of the most erupted maxillary and mandibular central incisors in relation to the occlusal plane.

    Measured: 12 months

Secondary outcomes (2)
  1. Changes in maxillary mandibular plane angle

    standardised lateral cephalometric radiographs will be taken, and the variables will be digitally traced using Dolphin Imaging Software Version 11.5

    Measured: 12 months

  2. Patient acceptance

    1. The questionnaire is consisted of 5 questions and has space for additional patient comments.
    2. The variables in the first four questions will assess speaking, eating, esthetics, and pain.
    3. The rating scale that will be used to quantify the effect of the spurs and the palatal crib on these variables 1 (easy), 2 (neutral), and 3 (difficult).
    4. The 5th question on the survey will assess the time needed by the patients to adjust the presence of the two appliances. Possible answers are 2 days or less, 1 week, 2 weeks, and longer.

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Palatal Crib and bonded spur in people with Anterior Open Bite, run by Reem Hatem Shams.

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 4 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 6 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Reem H Shams, B.D.S (01099898731 ext. 002, reem.shamseldin@dentistry.cu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overbite distance correction in millimeter (time frame: 12 months). 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 NCT05313399, which also lists 1 linked publication.

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 6 Apr 2022.
