The present work is focused on the skeleton prosthesis with Ney clamps, which is a removable dentine and belongs to the group of partial prostheses. Skeleton prosthesis (denture) was made as a replacement for 5 teeth of the upper jaw, where there is a possibility of physiological engagement to carry loading by the remaining teeth in the oral cavity. In order to imitate most correctly the complex geometry, the prosthesis has been scanned using the computer tomography technique. Using the obtained set of points (cloud of points) the model of the denture structure has been created using CAD program which in turn has been later applied for numerical analysis applying ANSYS 8 program. The boundary conditions and loading of the denture structure has been modelled in this program in order to determine the stresses and strains. The results of calculation are presented in graphical form.
