Sažetak
The bridge as a fixed prosthetic means for substituting teeth should be of unlimited duration in technical sense. This claim has been confirmed by a number of cases in which bridge production is based on modern principles of fixed prosthetics and the application of materials available nowadays. However, as a bridge consists also of the parts belonging to the living organism i. e. bearer tooth and bony basis and it is placed in an extremely active functional and physiological environment subject to changes it is justifiable to introduce the term of permanent usability of the bridge which esentially depends on environmental factors unlike its technical duration determined by construction and material. In this paper the authors point at the incidence and importance of environmental factors on the ground of their more comprehensive studies. In conclusion the need for a constant control of produced bridges is emphasized as a doctrinal attitude with the purpose of an early detection of the effects of environmental factors on their permanent usability.
