Details and patient eligibility

About

The aim of the study was to determine the changes in Oral Health-Related Quality of Life (OHRQoL) in patients with juvenile idiopathic arthritis (JIA) and temporomandibular joint (TMJ) disorders who underwent functional therapy for 24 months to assess the age and sex group in which the functional therapy was most effective.

Full description

This prospective interventional study included 93 patients with JIA and TMJ disorders at the start of functional orthodontic therapy. Children were prospectively followed in the 24 months of treatment and completed the Oral Health Impact Profile (OHIP-14) before treatment (T0), and at 6 months (T1), 12 months (T2), and 24 months (T3) after the start of therapy.

Enrollment: 93 patients

Sex: All

Ages: 8 to 20 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

The inclusion criteria were:

• JIA with unilateral or bilateral TMJ arthritis treated with a functional appliance;
• Clear signs or symptoms of TMJ arthritis based on clinical and radiological examination.
• No administration of intra-articular TMJ steroid injections throughout the course of the orthopaedic functional treatment.

Exclusion criteria

• previous orthodontic treatment;
• history of maxillofacial surgery;
• genetic diseases, syndromes, other congenital deformities or any concurrent medical condition.

Andresen functional removable orthodontic appliance

Experimental group

Description:

All the enrolled patients was applied the Andresen Activator (a removable orthodontic appliance) 12-14 hours in a day in total. Functional appliances helped the movement of the teeth, with the achievement of good facial muscle function. All patients in the cohort were treated with the andresen actovator appliancev for deep bite and class II malocclusion correction. The appliances were individually manufactured of acrylic resin, with a central screw and a vestibular arch, fabricated through a wax bite registration; the patient was guided to close the mouth in mandibular protrusion with coincidence of the upper and lower midlines. The registration bite was very thin in order to obtain a minimum vertical dimension. The activator was modified every three months increasing its posterior vertical dimension in order to stimulate the mandibular ramus growth thanks to the dislocation of the mandibular condyle.
