ANN-models for jaw-research

ANN models for the opening jaw starting from the closed position are studied here. The models link final tension values in four active jaw muscles to final jaw positions and final tensions in the remaining muscles. The models assume the jaw opens in the midline: thus, right- and left-side muscles have equal tensions, and jaw motion is in two-dimensions. We have examined two ANN jaw models. One gives jaw motion and passive muscle tensions given active muscle tensions. The other, possibly of practical use, gives jaw motion given active muscle tensions; passive muscle tensions appear as signals inside the model.
