About

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.

Full 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.

Enrollment: 22 patients

Ages: 5 to 18 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Trial design

22 participants in 1 patient group

Distraction splint therapy

Description:

All 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.

Treatment:

Device: Distraction splint therapy
