- ItemStress and Fatigue analysis of cantilevered bridge during biting: A Computer Study(TAYLOR & FRANCIS LTD, 2017) Henyš Petr; Ackermann Michal; Čapek Lukáš; Drahorád Tomáš; Šimůnek Antonín; Exnerová MartinaCantilevered bridge is a common replacement for patients who have a toothless mandible. The bridge is a cantilever fixed by 4–6 dental implants into interforaminal bone region. The excessive forces during biting can cause bone damage and resorption and even the breakage of dental implants and the bridge. The magnitude of the force is of a large variation between 400 and 1300 N (Koc et al. 2010). The bite force strongly depends on a sex factor and age (Zha and Ye 1994). The bite force has a dynamic character with large amount of cycles during life. This force character directly leads to a hypothesis whether the bridge fracture can be caused by fatigue damage. Despite the fact there are a lot of studies dealing with static analysis of biting force effect on implants, bone and bridge, the dynamical examination of excessive biting force has never been investigated and presents a potential explanation of bridge fracture.
