Threaded Tapered Screw Appliance, a Cost Effective Gear for the Management of Trismus

Abstract

Trismus is a condition commonly encountered by the dentists, causing limited mouth opening, interferes with oral hygiene, restricts access for dental procedures, and may adversely affect speech and facial appearance. The overall success of treatment depends on prompt recognition of the cause and initiation of appropriate management. Ideally trismus appliances are used in conjunction with physical therapy effectively for the management of Trismus due to muscle fibrosis or scar tissue that has not yet matured. Currently several trismus appliances either externally activated or internally activated are available commercially. This case report presents a simple and cost-effective approach for the management of Trismus using a Threaded Tapered Screw appliance.
