Device for simulation of a jaw has upper and lower supports for top and bottom jaw bone models and bearing points for simulation of the jaw joints that can be displaced relative to each other to simulate jaw dislocations

摘要

Simulation device has supports (15,19) for upper and lower jaw models, the lower jaw support (19) being linked to the upper jaw support by a joint (23) with a common transverse axis that allows the lower joint to rotate about it, to move sideways along it and to rotate about two axes perpendicular to this axis. The position of the joint (23) relative to the upper jaw support (15) can be moved. An upper jaw joint (25) can be moved relative to the lower jaw joint (23) so that the two work in conjunction.
