A New Intraoral Appliance for Trismus in Oral Submucous Fibrosis

Abstract EN

Trismus is the most common sequelae of various pathological processes leading to compromised nutritional state in addition to physical and psychological disabilities.

Therapeutic interventions are available to relieve trismus, which range from oral usage of pharmacological agents to intralesional steroid therapy.

Intraoral appliance therapy can be employed as an alternative or adjuvant treatment for radiotherapy-induced fibrosis and autoimmune disorders such as scleroderma, psychogenic trismus, and oral submucous fibrosis, decreasing the adverse effects associated with other pharmacological interventions.

A novel intraoral appliance—“Nallan C-H”—has been developed and tried for trismus producing better results.

A report on three such cases having trismus due to a premalignancy has been presented.

It is hypothesized that the same appliance can be used for treating inoperable trismus in palliative care setting additionally or as an adjuvant to pharmacological approach.
