A satisfactory finite element analysis model of the human mandibular and dentition system besides the detailed 3D geometry considers also static and time – dependent mechanical properties of different components of the jaw bone. The major role plays compact bone tissue. The aim of the work was to investigate the active creep of the compact part of human mandibular bone. Creep tests of 15 specimens were conducted at room temperature, with applied constant compressive stresses between 5 and 40.8 MPa. The obtained results were approximated with exponential function. Average values of the creep properties of human jaw compact bone tissue for 5 specimens group were achieved.
