Nociceptive Trigeminal Inhibition Device in the Management of Temporomandibular Disorder Secondary to Parafunctional habit: A Case Report

Abstract

Temporomandibular disorder (TMD) is a prevalent condition often associated with pain, functional limitations, and a significant impact on quality of life. Parafunctional habit is recognized as a contributing factor in the etiology and perpetuation of TMD symptoms. This case report presents the successful management of a patient with TMD resulting from parafunctional habit using a nociceptive trigeminal inhibition (NTI) device. The patient, presenting with chronic jaw pain, muscle tenderness, and restricted mandibular movement, showed marked improvement following the introduction of the NTI device as part of a comprehensive treatment plan. Within weeks, there was a notable reduction in pain intensity and muscle hyperactivity, as well as improved mandibular function. This case highlights the clinical utility of the NTI device in alleviating TMD symptoms linked to parafunctional habit, underscoring its potential role in non-invasive, conservative management strategies for TMD patients. Further studies are recommended to elucidate long-term outcomes and optimal patient selection criteria.
