Description	Complex reliability analyses of the bioimplants are very important today, because the failures of them cause traumatic consequences for the patients. We are interested in the calculations of the reliability of the ceramic heads of hip joint endoprosthesis. Reliability of the component made of the brittle material depends on the material parameters and on the tensile stress distribution in the component. Tensile stresses in the heads are very significantly influenced by the shape deviations of the cone contact areas of the head and the stem. The shape deviations may be modeled at the macro-level - deviation from the nominal degree of taper, and at the micro-level - when the stochastic distribution of unevenness on the contact areas is respected. The problem of stress in ceramic heads was solved using the finite element method under ISO 7206-5 loading. The simulations of the loading of the one head pressed on the 5 different stems cones is solved and analysed.
