In order to clarify jaw-movement mechanism, we have been developing an autonomous jaw-movement simulator with a life-like structure and control mechanism. The present simulator, JSN/2B, is capable of performing an open-close movement and a chewing-like movement autonomously. Before such motions, the intercuspal position, in which the opposing dental arches contact with each other as widely as possible, has to be established as an initial jaw position. In order to automatically accomplish such initialization, we developed a subsystem capable of obtaining the intercuspal position automatically, employing data of 3-D bite-force and tooth-contact sensors. Experiments where an open-close movement was optimized adaptively demonstrated that 1) the initial difference of bilateral bite-forces could be reduced by 36 %; and 2) the adaptation was completed faster than conventional cases. |
