- Primary Outcome Measures
Name Time Method The level of the maximum bite-, and tongue force and the duration of endurance may show a statistically significant difference at measurement time 8 (after approx. 300 days) compared to the initial value on measurement day 1.
- Secondary Outcome Measures
Name Time Method On day 10 (2nd measurement) or day 63 (3rd measurement) a significant deviation of maximum bite force or endurance time compared to the initial value (day 1) represents a secondary endpoint.
