<p>PROBLEM TO BE SOLVED: To provide an occlusal utensil which can provide a motion closer to a biomedical jaw motion, is inexpensive, and has a favorable operability in a non-adjustable dental occlusal utensil. SOLUTION: This occlusal utensil comprises an upper jaw section 4 and a lower jaw section 5, and the rotating shaft 2 of the upper jaw section is pressed to the lower jaw section by a plate spring 3, and combined to the lower jaw section. The movable direction of the rotating shaft is set at back-upward 45 deg. to the occlusal surfaces as a special feature. In this case, the angle is not limited to 45 deg., and an equivalent result can be obtained as long as the angle is set in a range of 40-55 deg..</p> |
