What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Carriere Motion 3D Class III ApplianceDevice
The device made of stainless steel consists of a flexible bar with two pads at the end which are bonded bilaterally with composite resin to the lower second deciduous molar or the lower first permanent molar at the rear and the lower deciduous canine at the front. The base on the lower deciduous canine has a hook to which bilaterally elastic latex bands are connected with the vestibular tubes of the cemented bands on the upper deciduous second molars (Force 2 elastics ) or on the first permanent upper molars (Force 1 elastics), on whose palatine surface the a rapid maxillary expander is welded.
Facial maskDevice
The facial mask consists of a chin pad and frontal pad connected by a central steel bar. On the central bar there is a horizontal steel bar to which latex elastic bands are attached which develop 14 ounces of force. The elastics are connected to the rapid maxillary expander by means of two hooks welded on the bands of the second upper deciduous molars or the first upper permanent molars.
| Study group | Role | What they receive |
|---|---|---|
| Carriere Motion 3D Class III Appliance | Experimental | Not described Receives: Device: Carriere Motion 3D Class III Appliance |
| Facial mask | Active comparator | Not described Receives: Device: Facial mask |
What is being measured
The primary outcome is the main question the study is designed to answer.
Wits appraisal
Distance between the perpendiculars from points A and B on the maxilla and mandible, respectively, onto the occlusal plane
Measured: Change in Wits appraisal evaluated on the lateral cephalograms taken at the start and at the end of active treatment (6-10 months)

Questions about this trial
What is this clinical trial studying?
A study testing Carriere Motion 3D Class III Appliance and Facial mask in people with Class III Malocclusion and Dentofacial Anomalies, Including Malocclusion, run by Azienda Ospedaliero-Universitaria Careggi.
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 8 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 9 Nov 2020. 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.
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?
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?
Wits appraisal (time frame: Change in Wits appraisal evaluated on the lateral cephalograms taken at the start and at the end of active treatment (6-10 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 9 Nov 2020; AzTrials last refreshed its copy on 7 Nov 2026.
