Trial summary

Temporomandibular joint (TMJ) arthritis is known to alter the mandibular development in children diagnosed with juvenile idiopathic arthritis. In a number of cases a genuine breakdown of cartilage and bone is seen in the affected joint which leads to asymmetric mandibular growth in the affected side. Read more about this study

About this study

Official title: Effect of Functional Treatment on Mandibular Asymmetry Caused by Unilateral Temporomandibular Joint Involvement in Children With Juvenile Idiopathic Arthritis

Temporomandibular joint (TMJ) arthritis is known to alter the mandibular development in children diagnosed with juvenile idiopathic arthritis. In a number of cases a genuine breakdown of cartilage and bone is seen in the affected joint which leads to asymmetric mandibular growth in the affected side. In cases of unilateral TMJ involvements severe mandibular asymmetric mandibular growth deviations are seen. We hypothesize that these growth deviations can be minimized and controlled by the use functional orthodontic appliance therapy.

Read the detailed description

This is a retrospective study design with the aim to evaluate the clinical procedures we have used the last 15 years to treat JIA patients with unilateral TMJ arthritis. More specifically, the purpose is to evaluate the mandibular growth in all JIA patients with unilateral TMJ arthritis and an asymmetric mandibular growth pattern treated with non-surgical distraction splint therapy between 1994 and 2010 at the dep. of Orthodontics, Aarhus University, Denmark. The evaluation is based on radiological examinations at the beginning of their non-surgical distraction treatment as well as after the patients have finished their distraction-splint therapy.

What participants receive

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

  • Distraction splint therapyDevice

    Also called functional appliance

    After the diagnosis of unilateral TMJ arthritis with clinical asymmetric mandibular growth deviations the JIA patients are offered treatment with a distraction splint. The appliance consists of an acrylic splint (distraction splint) covering the occlusal surfaces of the teeth in the upper or lower dental arch. The height of the splint is thereafter gradually increased every 6th to 10th weeks in order to optimize the mandible growth in the affected side and thereby reduce the overall asymmetric mandibular growth pattern(non-surgical distraction of the TMJ and mandibular condyle).

Study groups in NCT01113177
Study groupRoleWhat they receive
Distraction splint therapyAll JIA patients with asymmetric mandibular growth due to unilateral TMJ arthritis are offered non-surgical functional orthodontic splint therapy with a distraction splint. Mandibular growth is thereafter evaluated in the affected side compared with the mandibular growth in the healthy side of the same individual.

What is being measured

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

  1. Mandibular growth in children with unilateral TMJ arthritis treated with an acrylic distraction splint

    The craniofacial dimensions are measured radiologically prior to the start of the treatment with the distraction splint. Second measurements of the craniofacial dimensions are evaluated after the patients have ended the treatment with the distraction splint. In that way we are able to evaluate the craniofacial growth in the affected side compared to the craniofacial growth in the "healthy" side in JIA patients with unilateral TMJ arthritis. The succces of the distraction splint treatment is decided based the splints ability to normalize the craniofacial growth in the affacted side.

    Measured: average treatment with splint is 6.4 years

Questions about this trial

What is this clinical trial studying?

An observational study of Temporomandibular Joint Disorder, run by University of Aarhus at 1 site in Denmark.

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 1 inclusion and 2 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 9 Nov 2010. 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 Denmark. 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?

Mandibular growth in children with unilateral TMJ arthritis treated with an acrylic distraction splint (time frame: average treatment with splint is 6.4 years). 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 2010.
