Despite progress in the development of dentistry is still the most common way of substitution of small defects of dentition is a metal-ceramic prosthetic bridges. This type of fixed prosthesis meets aesthetic and functional requirements, however, depending on the selected design bridge load distribution function in different ways. The purpose of this study was to investigate the nature of the intensity distribution of stresses in the elements of a cemented bridge with medial support on two teeth and one artificial tooth console. For the analysis of mathematical model of the bridge. Evaluated Mises equivalent stress, the average hydrostatic stress and the maximum tensile stress. Data were obtained on the distribution of stresses in the components of a bridge abutment teeth and tissues, including periodontal and marginal gingiva.
