3D Characteristics, Functional Appliances and Sleep Related Breathing Disorders (FA PSQ HR)

December 5, 2024 updated by: Visnja Katic, University of Rijeka

Impact of Functional Appliances on 3D Craniodentofacial Characteristics and Reported Sleep Related Breathing Disorders in Children

Facial scans of the patients eligible for the functional appliance treatment (Twin Block appliance) will be taken prior to and after the end of treatment. Also, a facial scan of the predicted final outcome will be taken, and compared to the actual final outcome. Parents / caregivers will fill out the Pediatric Sleep Questionnaire (PSQ) prior to and upon the end of treatment to asses perceived influence on sleep related breathing problems in their children.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The harmonious growth of the upper and lower jaw enables further favorable development of the orofacial region and the functions of breathing, chewing, swallowing and speaking, as well as the general growth and development of the child. Translation into Croatian and administration of the questionnaire for early detection of sleep disorders related to breathing in children (PSQ) will enable triage and early recognition of children with sleep disorders, which also affect general psycho-physical development. The impact of functional appliance therapy (FA) on changes in craniodentofacial characteristics, dimensions of the upper airway and sleep problems in children will be determined. The non-invasive three-dimensional representation of the face surface provides information about the surface and volume of the observed object, which is used for better diagnostics and therapy planning. Class II is a frequent malocclusion, characterized by a discrepancy of sagittal interjaw relationships. The diagnostic method, which helps in deciding on a therapeutic approach, is the so-called Fränkel maneuver (FM). By comparing the observation of the soft tissue profile of the subjects at rest and after the application of FM, a decision is made on the therapeutic approach. Previous research indicates the validity of using FM in making a decision about FN therapy, with high reliability and consistency. The analysis of latero-lateral (LL) X-ray cephalograms in numerous studies has provided a series of data, which is used, among other things, to assess the remaining growth in order to apply FN therapy in a timely manner, but also to expect a desirable response. The evaluation of the success of therapy based on FM don't exist, because a reliable 2D analysis through LL cephalogram would require additional radiation of the subjects. Research indicates that the analysis of scan surfaces is more appropriate than the analysis of anatomical points for detection of the area and amount of changes.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • retrognathic mandible, increased overjet

Exclusion Criteria:

  • craniodentofacial deformities

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Functional appliance group
Upon diagnostics, functional appliance Twin block will be proposed to the participants for one year.
Device: functional appliance twin block
3D facial scans will be taken (prior to the treatment, at rest and at mandible moved forward to class I dental relation (Fraenkel manouver)) and at the end of treatment, one year later.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Facial scan
Time Frame: from enrollment and predicted outcome to the end of treatment at one year on average
Using stereophotographic camera, 3D facial scans will be taken, and superimposed to observe differences prior to and at the end of treatment. Also, predicted outcome (facial scan taken in Fraenkel manouver position (at start)) will be compared to the actual outcome after one year of treatment with functional appliance Twin Block.
from enrollment and predicted outcome to the end of treatment at one year on average
PSQ questionnaire
Time Frame: from enrollment to the end of treatment at one year on average
Parents / caregivers will fill out the PSQ questionnaire to assess influence of the functional appliance treatment on the sleep related breathing problems in their children.
from enrollment to the end of treatment at one year on average

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
