Measurement of mechanical strain on mandibular surface with mastication robot: influence of muscle loading direction and magnitude

Abstract

These results suggested that the muscle loading generated the mechanical strain on the mandibular bone surface and it was affected by the changes in loading direction and magnitude.

Development and validation of a mastication simulator

“…Many devices are designed to measure the flavour release from foods during chewing (Nassl et al, 1995;Van Ruth et al, 1995). Others oriented towards mechanical properties make no attempt to reproduce the conditions in which foods are prepared within a closed mouth (Hoebler et al, 2002;Usui et al, 2003;Conserva et al, 2008). Mathematical models have also been proposed (Kato et al, 1988;Peleg and Normand, 1982;Van der Bilt et al, 1992;Daumas et al, 2005;Pap et al, 2005).…”

Mechanical loading and how it affects bone cells: The role of the osteocyte cytoskeleton in maintaining our skeleton

“…During physical activity, mechanical forces are exerted on the bones through ground reaction forces and by the contractile activity of muscles (Lanyon et al, 1975;Usui et al, 2003). These physical forces result in a maintenance or gain of bone mass, but also drive adaptation of bone structure.…”

An update about artificial mastication

“…Development of a series of mastication robots was carried out for quantitative and dynamic assessment of mechanical stress applied to oral elements during oral activity. The 'Waseda Jaw (WJ)' systems were mostly developed to analyze the mechanical effects of mastication on jaw bones in terms of position, force, velocities and muscle controls [14,15]. A second example of a mechatronic chewing device is of particular relevance since it can reproduce the entire suite of complex functions and movements involved during mastication, encompassing most of oral applications [16,17].…”
