Hegab TMJ Splint (HTS)

Successful treatment of the TMJ internal derangement is based on understanding the biomechanical performance of the TMJ and subsequently to understand the biomechanical changes within the TMJ resulted from the occlusal splint to achieve harmonious relationships among teeth, joints, and muscles. As the disc displaced anteriorly, the elevator muscles continue to seat the condyle in the fossa resulting in decreasing the joint space and posterior-superiorly movement of the condyle. The aim of the splint is to move the condyle downward and foreword besides movement of the disk toward the normal position. These movements resulting in increasing the joint space, decreasing the joint pressure especially on the posterior attachment of the articular disk. Moreover; the vertical thickness of the occlusal splint return the normal physiologic function of the masticatory mechanism by relax the masticatory muscles by decreasing the electrical muscle activity and re-establish the disk condyle relationship (disc re-capture).4
