Abstract
It is intended to provide artificial teeth designed to easily enable bilateral balanced occlusion with less grinding adjustment. According to the present invention, angles formed by occlusal facets of the artificial teeth with an occlusal plane are suitably set. An artificial tooth for maxillary central incisor, for example, has a protrusive facet and a retrusive facet on an incisal edge thereof. Of angles formed by the protrusive facet with the occlusal plane, the angle in cross section along a sagittal plane is 22.0° to 25.5°, and the angle in cross section along a coronal plane is 1.5° to 6.5°. Of angles formed by the retrusive facet with the occlusal plane, the angle in cross section along the sagittal plane is 20.5° to 23.0°, and the angle in cross section along the coronal plane is 1.5° to 6.5°.
