Application of strengthening elements in dental bridges for both fixed and removable prostheses essentially extends possibilities of lost teeth reconstruction as well as increases the range of transfered occlusal loadings. The paper presents comparative numerical analysis of the reinforced polymer-based fixed prosthesis used for a reconstruction of the total teeth lack in anterior mandibular part. The strengthening bars of various cross-sections were made of stainless steel, titanic alloy, ceramics and glass composite. The stress distributions in the elements of prostheses as well as the analysis of effort in the mandibular bone structures close to the supporting pillars have been done for the case of bite occlusal loadings.
