In own FEM models, three types of non\-linearity were considered\: geometric, material and non\-linearity related to the change of terminal conditions. Calculations were performed on a PC computer with Intel Pentium IV 3 GHz processor and Strand 7 Software by G\+D Computing as the digital environment to generate the numerical model of prosthetic base with bilateral free\-ends, namely edentulous molar areas with preserved anterior\-lateral arch up to second premolars inclusive. Designing of the model with the finite elements method comprised the following stages\: 1\) use of numerical bar models as simplified mathematical models, 2\) performance of individual models of premolars obtained with tri\-dimensional analysis \(scanning\) of roots of premolars extracted for orthodontic reasons, 3\) generalization of mathematic models of the roots of abutment teeth in the form of double cut cones for the purpose of obtaining a 3D model of finite elements of the prosthetic base, 4\) performance of the analysis on the axially symmetrical 3D models of prostheses and the analysis on twodimensional models constituting their axial cross\-sections. The prosthesis comprised fixed restorations, namely crowns fixed to the patient's own abutment teeth, made of chromium\-cobalt alloy. Together with the crown, on the common metal frame,"]
