Реферат: The study aims to assess the primary stability of the prosthetics on 8 implants for edentulous maxilla. Cases of individual implants failure and different bone mineralization are considered. The model of the maxilla was made in accordance with the three-dimensional tomographic image. Modeling of primary stability failure of implants under the influence of various loading cases were carried out. Bone materials were assumed to be isotropic, but normal and critical bone mineralization were considered. The problems were solved using the finite element method. The Coulomb-Mohr strength criterion was used to assess the primary stability. Critical prosthetics scenarios depending on the implants failure configuration and degree of bone mineralization are indicated on the basis of criterion. The most critical schemes of implant failure in the distal region for any type of mineralization with unilateral chewing load. The considered configuration of the prosthesis on 8 implants increases the risk of damage the cortical bone with age, even when all implants have survived.
