14.4 Results and Discussions
The aim of the research is to study an influence of teeth role parameters (installation
line and tilt angle) on the stress distribution and structural integrity of prosthesis
basis under typical chewing loads. According to the medicine practice, the teeth
installation line can be shifted to the oral or external sides, see Fig. 14.4a, b. The
common practice is to adjust the position of individual teeth blocks to the individual
