The analysis of the intensity distribution of stresses in bridges with bilateral support in the construction of biomechanical system of the tooth root, periodontium, metal frame, ceramic coating of the bridge. The study found the largest concentration zones of stresses in bridges at different load directions (vertically-buccal and vertically-lingual) as the most common during functioning of the prosthesis. It was also studied the occurrence and distribution of compressive and tensile stresses in the root of the abutment teeth and their periodontium, framework and ceramic coating of metal-ceramic bridge. Such analysis allows us to more closely approach the planning process of the design bridges with bilateral support and also will help to reduce the risk of complications and improve the quality of prosthetic treatment with non-removable prostheses.
