Abstract

A therapy device is provided for trismus prevention and treatment, and includes a first arm hingedly connected to a second arm, and a spring device disposed therebetween to press the first and second arms apart. A pair of bite pads are provided at the ends of each of the first and second arms and are designed to be engaged by a user's teeth or gums in order to bite down on the device to exercise the user's jaw, and more specifically, the muscles of mastication.

Claims (46)

1. A therapy device for trismus prevention and treatment, comprising:

a first arm having a first end and a second end, said first arm including a first recess portion disposed between said first end and said second end of the first arm and closer to said first end than said second end of the first arm and a first bite pad disposed at said second end;
