Most mouthstick prostheses previously described in the literature have severely limited application or availability. They are either highly specific and sophisticated and difficult to fabricate or very crude and unifunctional. Most do not conform to basic functional and physiologic criteria as outlined, nor are they sufficiently flexible to meet the various needs and physical capabilities of of a wide spectrum of patients. The prosthesis described is adaptable, and with the basic bite-stick and the friction-grip lock, the patient can change the form and function of the device to perform various tasks independently. The prosthesis is simple, inexpensive, and easy to fabricate and repair, and it needs no specialized or sophisticated parts. It enables handicapped patients to attain a greater degree of self-sufficiency than was previously possible, which improves their mental outlook.
