It is now very widespread prosthesis with partial loss of teeth by metal bridges. At the same time, the accumulated clinical experience shows that this treatment is far from perfect, which is connected on one side to another frequently occurring errors in the technical performance of prostheses, and on the other - with clinical methods of prosthetics. This particularly applies to the planning design cermet prosthesis in various clinical conditions caused primarily of extended defects of the dentition, the size of the clinical crowns of natural teeth and their position in the alveolar bone, periodontal condition and toothless alveolar portion of remaining teeth, bite and views etc. An important role in solving practical problems prosthetic dentistry takes character study elastic stress distribution in periodontal tissues supporting the teeth under the influence of prostheses. This biomechanical study focuses on a comparative analysis of the impact of the construction of a bridge on the intensity of the stresses in the prosthesis and its components, including metal frame, ceramic tiles, cement retaining layer and tissue supporting the teeth and periodontal. The results of the study indicate the uneven intensity distribution of stresses in the supporting elements of the teeth prosthesis, and, depending on its design.
