Prosthesis, artificial substitute for a missing part of the body. The artificial parts that are most commonly thought of as prostheses are those that replace lost arms and legs, but bone, artery, and heart valve replacements are common (see artificial organ), and artificial eyes and teeth are also correctly termed prostheses. The term is sometimes extended to cover such things as eyeglasses and hearing aids, which improve the functioning of a part.

The procedure includes: (1) the establishment of a proper concept of prosthetic service in the mind of the patient and the development of a proper psychologic attitude toward this service, (2) thorough examination of the oral conditions and roentgenographs, (3) muscle therapy which includes an exercise prescription, (4) removing any prosthetic appliance from the mouth for a minimum of 14 hours before impressions are made, (5) tissue stimulation and cleansing, (6) removing and cleansing the existing dentures, (7) temporary relines, and (8) vitamin therapy, general diet, and proper consideration of general systemic conditions.

Orthotics:

Orthotics are special shoe or heel inserts a doctor prescribes that are custom-made specifically for you.

Orthotics can be part of a comprehensive treatment plan to address various symptoms, usually having to do with pain and discomfort of the feet and legs. Some of the goals a doctor may have for orthotic treatment include:

Correcting foot deformities

Helping the foot or ankle function better

Providing support to the ankle

Reducing the risks for further injuries
