# Efficacy of the CerveraTS Plate in an Integrated Approach to Juvenile Idiopathic Arthritis: A Long-Term Case Report

## TL;DR

A 10-year-old girl with juvenile idiopathic arthritis and TMJ issues showed long-term improvement using a CerveraTS plate and therapy.

## Contribution

Demonstrates the efficacy of the CerveraTS plate in managing TMJ-related JIA over a long-term follow-up.

## Key findings

- Pain remission and improved mandibular range of motion were observed after three months of treatment.
- Sustained therapeutic outcomes were reported after one and three years of follow-up.
- The CerveraTS plate proved effective in improving TMJ function and resolving pain in JIA patients.

## Abstract

Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of unknown etiology affecting children. Temporomandibular joint (TMJ) involvement has been reported in up to 96% of children with JIA. This paper presents a case of JIA with TMJ involvement, emphasizing the clinical features and therapeutic management of the disease. This is a case of a 10-year-old female who presented with pain localized at the left mandible angle during end-feel assessment. During examination, reduced range of motion (ROM) and limited right lateral excursion were observed. Afterwards, a comprehensive multidisciplinary evaluation led to diagnosing the patient with oligoarticular JIA involving the TMJ. Treatment modality included cognitive behavioral therapy, left-sided joint distraction exercises to reduce intra-articular pressure and relax affected masticatory muscles, and a modified CerveraTS plate. Three months of posttreatment follow-up showed pain remission, improved ROM, and enhanced right lateral excursion. Sustained therapeutic outcomes were reported after 1 and 3 years of follow-up visits. The case emphasizes the importance of early diagnosis of JIA with TMJ involvement and tailored management using functional appliances such as the CerveraTS plate which has proved its efficacy in improving mandibular function and pain resolution.
