Rehabilitation of mastication function and oral aesthetics of the patient

What are dental prostheses?
Dental prostheses are prosthetic devices which substitute missing natural teeth. In order for the masticatory system to function adequately the teeth need to be in balance on the upper and lower dental arches. The loss of just one tooth unbalances this system of forces and the teeth move themselves to compensate for the loss. Gaps are created, unevenness occurs and both the aesthetic aspect and the ability to chew suffer. The teeth then need to be replaced.

How many types of prosthesis exist?
There are 4 types of prosthesis:
1. Partially fixed or fixed bridge;
2. Partially removable or movable bridge;
3. Completely movable or denture;
4. Fixed or movable over implants;
